Helical Insight for ETL Tester (QA)

Helical Insight for ETL Tester (QA)

Let’s take an example that your ETL developer has just wrote an ETL script, which loaded the data into the Data Warehouse, few millions of records got inserted into the Data Warehouse.

For QA, it is super difficult to test all (millions) of the data and also a time consuming process. Moreover, there are many other problems like

  • some might not be well versed with writing complex SQL queries
  • There might be multiple data sources involved in generating the Data Warehouse.
  • Writing multiple queries on multiple data sources and then combining it in one single result set would be a sweat breaking task.

Now think of Helical Insight as your friend which helps you to do most of your tasks, allowing you to focus on more critical thinking rather than just doing stare and test whole day. Wondering how Helical Insight can help you achieve the same?

Here is your answer,

  • Helical Insight is capable of communicating with any of your data source(s) like CSV, Excel, MySql, Oracle, SQL Server, Postgres etc.
  • Helical Insight has a drag and drop feature to make your test cases ready, without even having a prior knowledge of SQL queries. Helical Insight generates the SQL queries including the joins between multiple entities. Helical Insight understands your data structure, hence it generates the query even if you are working with different set of data source(s), DW or normalized database, Helical Insight understands all.
  • Using this (drag and drop) facility you can generate all your test cases in a form of report, which you can call it as your test cases. For example, your report does a count of records for a dimension. You can save this report and check the same with source system by creating a separate report. If its a migration project the count should definitely match otherwise we know something is wrong with the ETL Script.
  • Once you have saved these reports (test cases) you can re-executes them again an again to verify your data. In the above situation you have just identified that Helical Insight is really a very useful tool with some really cool features like generating the SQL query for any database or data source(s), ability to execute the queries on any databases or data source(s), ability to save the report / test cases / SQL queries for future usage.

Creating HTML Table with JSON Data dynamically in HDI(Helical Dashboard Insights)

This blog will teach you how to create HTML Table with JSON Data dynamically in HDI(HelicalDashboard Insights) :

To create html table with json data dynamically in hdi , we need two files

  1. Demo.EFW
  2. template.html

In “Demo.EFW” file , we have to call template.html file

Demo.EFW:-

<?xml version=”1.0″ encoding=”UTF-8″ ?>

<efw>

<title>HDI Demo</title>

<author>Rupam</author>

<description>Demo Dashboard</description>

<icon>images/image.ico</icon>

<template>template.html</template>

<visible>true</visible>

<style>clean</style>

</efw>

In “template.html” file ,

  1. we have to declare in which portion of the dashboard we want table to be shown
  2. JSON data
  3. Script that will automatically add the json data to table

 

Template.html : –

<div id = “myTable”></div>

<style type=”text/css”>

td, th {

padding: 1px 4px;

}

</style>

<script>

var data = [{“id”:”1″,”Name”:”Rupam”,”address”:”Hyderabad”}];

var peopleTable = tabulate(data, [“id”, “Name”,”address”]);

function tabulate(data, columns) {

var table = d3.select(“#myTable”).append(“table”)

.attr(“style”, “margin-left: 250px”),

thead = table.append(“thead”),

tbody = table.append(“tbody”);

 

// append the header row

thead.append(“tr”)

.selectAll(“th”)

.data(columns)

.enter()

.append(“th”)

.text(function(column) { return column; });

 

// create a row for each object in the data

var rows = tbody.selectAll(“tr”)

.data(data)

.enter()

.append(“tr”);

 

// create a cell in each row for each column

var cells = rows.selectAll(“td”)

.data(function(row) {

return columns.map(function(column) {

return {column: column, value: row[column]};

});

})

.enter()

.append(“td”)

.attr(“style”, “font-family: Courier”)

.html(function(d) { return d.value; });

return table;

}

</script>

Overcome Jasper Reports Complexities using PLPGSQL

This document is to help users to overcome jasper reports complexities using PLPGSQL (Postgres Stored Procedure function). Will look into the complexity with input controls of type multi-select query and how to cascade them.

Creating a stored procedure function in plpsql, as we are dealing with multi-select query we need to create a stored procedure function with Array , there is also function VARDIC available in plpgsql but using Array is much easier.

Complexity 1:

Example: How to create a stored procedure function for type multi-select query input control.

CREATE OR REPLACE FUNCTION multiple_m1(text[])

RETURNS TABLE(comp_id integer, comp_name text, comp_sort text) AS

$$

BEGIN

IF  ‘Khosla’ = ANY($1) THEN

    RETURN QUERY SELECT id::int as comp_id, ltrim(company.compname)::text as compname, ltrim(company.compname)::text as sort

    FROM company where deleteflag = ‘0’ and active = ‘1’

    and id in (270,394,376,396,403);

ELSEIF ” = ANY($1) THEN

    RETURN QUERY (SELECT id::int as comp_id,ltrim(company.compname)::text as compname, ltrim(company.compname)::text as sort

    FROM company where deleteflag = ‘0’ and active = ‘1’

    UNION SELECT -1::int AS id, ‘All’::text AS compname, ‘ ‘ as sort) order by sort;

ELSE

    RETURN QUERY SELECT id::int as comp_id,ltrim(company.compname)::text as compname, ltrim(company.compname)::text as sort

    FROM company where deleteflag = ‘0’ and active = ‘1’

    and (compname like ANY($1) or ” like ANY($1));

END IF;

RETURN;

END;

$$ LANGUAGE plpgsql

 

How to call function in Input Control?

Select * from company_multiple_m1 (‘{“”}’);

{“”} = NULL.

Create another Input Control of type Multi-Select Query. Here is another I/P control where comp_id column value of “multiple_m1” (Input control) is the input of my 2nd I/P Control. So My 2nd I/P control runs based on the comp_id value of 1st I/P control. This is nothing but cascading.

 

CREATE OR REPLACE FUNCTION mulitple_m2(integer, integer[])

 

RETURNS TABLE(id integer, reference integer, job_title text, status text) AS

 

$$

 

BEGIN

 

IF -1 = $1 THEN

 

RETURN QUERY select jobs.id::int, jobs.reference::int, jobs.job_title::text, ltrim(substring(jobs.status,3,char_length(jobs.status)))::text as status 

 

FROM jobs ,company c

 

where jobs.”DeleteFlag” = ‘0’

 

and c.id= jobs.id and c.DeleteFlag = ‘0’ and c.active = ‘1’

 

and (jobs.id = ANY($2) OR ‘-1’= ANY($2))

 

order by jobs.job_title;

 

               

 

ELSEIF 1 = $1 THEN

 

RETURN QUERY select jobs.id::int, jobs.reference::int, jobs.job_title::text, ltrim(substring(jobs.status,3,char_length(jobs.status)))::text as status

 

from jobs ,company c

 

where jobs.”DeleteFlag” = ‘0’ and jobs.status = ‘1: Open Req’

 

and c.id= jobs.id and c.DeleteFlag= ‘0’ and c.active = ‘1’

 

and (jobs.id = ANY($2) OR ‘-1’ = ANY($2))

 

order by jobs.job_title;

 

 

 

ELSE

 

RETURN QUERY select jobs.id::int, jobs.reference::int, jobs.job_title::text, ltrim(substring(jobs.status,3,char_length(jobs.status)))::text as status

 

from jobs ,company c

 

where jobs.”DeleteFlag” = ‘0’ and jobs.status = ‘0: Inactive’

 

and c.id= jobs.id and c.DeleteFlag= ‘0’ and c.active = ‘1’

 

and (jobs.id = ANY($2) OR ‘-1’= ANY($2))

 

order by jobs.job_title;

 

END IF;

 

RETURN;

 

END;

$$ LANGUAGE plpgsql

Cascading value of Parameter 1 into Parameter 2?

SELECT * FROM mulitple_m2($1,$2);

SELECT * FROM mulitple_m2($1,ARRAY[$P!{mulitple_m1}]::integer[]);

 

Complexity 2:

If let’s say your Input Control off type Multi-Select Query value is String and if this value is passed on your SQL Query. Your SQL Query does not works with $X{IN,}

$X{IN,column_name,parameter} does not works with plpgsql. It throws Error Message saying that Column “Column_name” does not exist.

Hence $X {} does not work in Jasper server when dealing with Stored Procedure.

Another work around is to pass $P{} in your SQL instead of $X{} and it throws an Error saying that “parameter type not supported in query : parameter_name class java.util.Collection”. Hence $P can be used.

Another work around is to pass $P{} with exclamation as $P!{parameter} in your SQL instead of $X{} and it throws an Error saying “org.postgresql.util.PSQLException:  syntax error at or near “[” ”

What is that Error? Where is that Syntax Error?

The reason behind this is your jasperserver passing String Values like [AJ, alexandra, Amanda, Amy, andrea, Angie, API]. Your SQL statement does not accept string values without single quotes. Thus in order to add single quotes to the parameter values, we need to perform at java end and then to pass those values on SQLquery.

How to perform it?

1. Add another parameter on the report.

Jasper Reports using PLPGSQL

    2. In expression field using Join function of Java, add single quotes along with Array and pass this parameter into SQL query.

EX:

“ARRAY[‘”+$P{parameter _m1}.join(‘\’,\”)+”‘]”

 

2)      3. Know your SQL query looks like

SELECT * FROM Nofsubmitted_report($P!{parameter _2});

Complexity 3:

If let’s say your Input Control off type Multi-Select Query value is Integer and How we pass this Integer array (collection) to call plpgsql function.

As we know $X{} and $P{} does not works in Jasper Server when dealing with stored procedure function, we have also seen what error throws when we use it.

The solution i found is to pass value with in Array like

SELECT * FROM function_name(ARRAY[$P!{parameter_m1}]);

Best Practices when designing & using iReport /Jaspersoft

This blog talks about the best practices which should be followed when creating reports using iReport or Jasper studio, deploying the same on Jaspersoft server, nomenclature to be used etc.

 

1) Report Margins:

When you develop reports for dashboards, it is advisable to keep all the margins with 0 pixels.

By default margins will be
Left margin         20
Right margin       20
Top margin         20
Bottom margin    20

Change the values to 0

Left margin         0
Right margin       0
Top margin         0
Bottom margin  0

Why?
Because, when set to 0 report panels are well fit when designing the dashboards.

 

2) Bands to keep the components

Do not keep table component, cross tab component in Detail band. Keep all the components either in Title band or in Summary Band as per the requirement. It is advisable to create custom bands to keep the different charts if you need to develop a report with multiple charts.

Why it is not recommended to keep the components in Detail band?

Details band falls into loop till the end of the row/data for fields hence if you keep any other component it will fall in a loop and will give you unexpected behaviour of iReport with bad output.

3) Parameter Naming conventions

It is advisable to give good naming conventions for parameters. For example parameter name could be param_paramName or p_paramName

Eg : 1)  p_startDate 2) p_endDate

Other Naming conventions
The same thing you can apply when you create input controls /Data source Names/Custom band names/Data Set names in iReport & Jasper Repository respectively.

Why ?

Easy to differentiate the variables, parameters and group names etc

4) Remove the other bands which you are not going to use in iReports

5) Variables and Parameter usage in iReport

Make use of internal parameters for the report and for the summation of columns recommended to use the variables.

6) Jasper Project Folder Structure

Project Name

archive (take a back up of jrxmls if you are going to update/modify them in this folder with a version number)

      Resources
     Input Controls ( All your parameter names for the project/various reports)
      Data sources(This folder is useful when you have multiple databases to use in your project)
      Files(Keep all your data source files here, for eg : Excel, CSV, XML and etc)
      JRXML’s (Whatever the JRXMLS you are creating you can keep all of them in this folder)
      Sub Reports(keep all you sub reports in this folder and refer from here where ever you want)
      Images(Keep all your images in this folder- for easy understanding)
      Reports(Keep all your reports in this folder)
      Dashboards(Save all your dashboards here)
      Temp (for temporary files)
      Test (Do experiment at the time of development of report in this folder)

Note that if your project is having lot many reports according to some sections/departments, it is advisable to sub divide the Reports folder with other folders.
For example:
Reports
    A.Department-1
         1.Report Name
         2.Report Name
    B.Department-2
        1.Report Name
         2.Report Name

 NOTE:

When you upload a report to JRXML it is recommended to write the description of the report. By seeing it every one can easily understand the purpose of the report/visualization.

7) Export / Import Utility

Command line utility to import/export/update folders/reports from the jasper server is given below.

Importing
js-import –input-zip(space) <Filename>
Ex: js-import –input-zip(space)”E:Work Space\Unified\Unified Reports\<file name>”

Updating
js-import –input-zip(space)”E:Work Space\Unified\Unified Reports\<file name>” –update

Exporting
js-export <location of the folder in jasper server> –output-zip <location of exporting folder>/<exporting_filename.zip>

8) Bands

Title band:

·         Every report must have some name, give the name of the report in this band.

·         Blue colour back ground with white colour font is preferable to give the titles.

·         Logos of the company are recommended to be placed left side of the band in title band under the title of the report.

Page Header:

·         Page header consists of the page numbers and date type of information. It is recommended to give page header information for long reports with heavy text involved in the reports.

Column Header:

·         This band is used for giving column headers for the fields. You can change the font style, size, give the borders, back ground colours and etc.

Detail band:

·         Detail band is used to display the output of the report using fields fetched by the query.

·         You need to drag and drop required fields to create the report to Detail band format them accordingly.

·         Detail band falls into for loop so we should keep only fields in this band rather than keeping any other component like table , cross tab, chart components.

Column footer:

 ·         This band is used to find the total, max, min of the columns from the details band.

·         You need to create variable for this and drag that variables under the column where you want see the sum, max or min

Page footer:

·         Page footer is used to place the page numbers, confidential type of text for the company etc.

Summary:

·         Summary of the report will be placed in the summary band.

·         Generally we keep the chart component, table component, cross tab component to summarize the report.

9)   9) Why should we keep input controls and data sources in resource folder?

  

Input controls in repository:

Create all your input controls in resource folder because every time for each report you need not to create the same input controls. You just need to link the existing input control from the repository folder.

Data sources in repository:
It is considered as a best practice to create data source connections in a folder called resources  and use this data source for the reports. It’ll reduce the report development time. You need to not create import database connections from iReport once you create this connection in the repository.

Embedding BI Reports (Jasper Reports/ Jasper Server/ Pentaho Reports/ Pentaho Server)

There are many methods of embedding BI reports, this blog tries to explain the meaning of Embedded BI, different approaches which can be used, their respective advantages and disadvantages

 

A)     What is embedded BI?

Lets say you have developed your entire BI solution which includes reports, dashboards, mashups, analysis etc, the platform which is used can be anything like Jaspersoft or Pentaho. The process of integration of this BI solution with your existing application/software/portal is called Embedded BI.

Embedded BI provides a lot of advantages like ability to add more reports over and above the existing canned reports which your application might provide, the look and feel and customization of all the reports can be changed as per the software/user preference, better visualization, unified application for everything. Biggest advantage can be your product value will increase much more, hence resulting in much more sales and revenue.

a) Embedding using iFrame Method :-

iFrame method of embedding BI reports can be used for embedding Jasper server, Jasper reports and Pentaho server, Pentaho reports. The report pulled in this case is using iframe as a tag. Even though the report is external, but to an end customer he will not be able to recognize the same.

The advantages of using iFrame method is this method is fast and quick to implement. The disadvantages includes it will be difficult to manage user, also in this case there can be cross browser compatibility issues, security is a major issue here.

 

b) Embedding Using webservice:- Webservices can also be used to integrate reports, dashboard, interactive report or/and ad-hoc reports. We can use webservices to accept the information from the Jasper/Pentaho server, this Jasper server can be anywhere ( on Tomcat or any other server). Using webservices we will invoke the response from Jasper Server/Pentaho server. This response can be can be then embedded inside application/software. Jasper server/Pentaho server also supports RESTFUL service (JSON format responses). In this approach there are no or less security related issues.

The disadvantage of this approach is there are no interactive features available of the report which thus results in poor user experience. Also in order to handle and understand the responses from jasper server/Pentaho server, custom coding is required in the application. In case if we had put input controls in the report, the same functionality then needs to be implemented in the application via custom coding. Aside, having many webcalls at times can be resource intensive as well.

The advantage of this approach is webservices approach gives more seamless integration since there is no security issue and no thirdparty calls (like in the case of iframe). Also in this case there are no interbrowser compatibility issues (assuming it is handled by your developer team).

c) Embedding using Jasper/Pentaho Libraries:- In this method we create JRXML/Pentaho report (prpt) files using ireport/Pentaho report designer. Compile these reporting using Java API, and then use this compiled code to generate views using Jasper Server API calls

The advantage of this method is this gives the most seamless integration. Also since all the information is present as a part of the application/server, no third party calls are required.

Disadvantage of this approach is some interactivity is lost in this method. Also the input parameters are also required to be created in the own application via custom coding.

 

Please get in touch at [email protected] for much more details about the respective approach, how to embed the same using these approaches, which was is the best suited to your needs and much more.

Tech Tips in Penaho Server – publishing password setting for server – Disable the folder names in Browser panel in the Server

Hi guys..

The below tips are very useful in Pentaho Server for BI developers.
1) publishing password setting for server
You need to publish the reports or schema(s)[developed in PSW] once you done with developing. For this you need set the publishing password for Pentaho server.
Go to this location 
<location of Pentaho>biserver-ce-4.8.0-stablebiserver-cepentaho-solutionssystempublisher-config.xml and edit the “publisher-config.xml”  file.

Give your publish password b/w  these tags  <publisher-password> </publisher-password>

Example:
<publisher-password>password</publisher-password>    ( password can be any name that you wish to give)

Snapshot is a worth more than text. find the image below.

Save the file. stop the server and start the server.

2) Disable the folder names in Browser panel of Pentaho Server
* What ever the folder you create in Browser panel of pentaho server, it directly stores   under pentaho-soulutions
i.,e in this location
<Pentaho location>Pentahobiserver-ce-4.8.0-stablebiserver-cepentaho-solutions
* You can disable all of your folders that comes with installation & the later created ones  which you don’t want to appear in the browser panel.
*   Inside every folder(pentaho default or the folders created by you) you can find “index.xml” file. You need to edit this file. You need to change visable tag as “false”.
Find the sanpshot.

You need not restart the server. Just you need to refresh the browser panel in the server.
You can observer the invisibility of the folder.

Date Input Controls/ Components in Pentaho CDE with a working example

Hello guys…!!!

In this post you will learn about how to create date input controls in CDE.
The dashboard images which I am going to show below are having lots of .css code. I’m not covering all the things but concentrating only on Date input controls in CDE.

My Environment :
BI Server: Pentaho 4.5
CTools: Not found the version numbers of  C-Tools(Unable to check them)– perhaps..! lesser than 13
Database : hsqldb (Comes along with Pentaho installation — A java based small db for servers like pentaho)
NOTE: Images are taken in this post after creating the dashboard, please find the yellow rectangular boxes to understand.

You need to work out @ 3 places in “Components” section.
1. Generic
2. Selects
3. Charts
Explained from step 1 to step 3
You need to work out  @ 1 places in “Data Sources” section. i.e, all in “Properties”
I’m not concentrating on Layout part for this example. So wherever the HtmlObject you find in this example replace them with your working HtmlObjects.

Step 1: Creating parameters
* Design your dashboard as per your requirement ( In the images you can find the sample designs).
 In the “Components” section:
1. Click on components
2. Click on Generic
3. Click on Date parameter
4. Go to properties give the name
eg: param_start_date
5. Click + symbol  per another date parameter
6. Go to properties give the name
eg: param_end_date

Find the  image

Step 2: Creating Date input Components
In the “Components” section
1. Click on Components
2. Click on Selects
3. Click on “Date input Component”
4. Go to Properties give name. eg: start_date in  my example
5. In the properties give HtmlObject. eg: start_date_select
* HtmlObject is the name of the column where you are putting
your dateinput control.
6. Give  Parameter.[It will appear once you try to type]
eg: In step 1, created parameters. So here give “param_start_date”
7. Give Listeners[click on it, you will find the list of Listeners. Click OK]
8. Repeat 3-7 for “end_date” Date input
component.

Step 3:
Find the steps in image.

 
HtmlObject is the place where you are putting your chart.

Step 4: Applying parameters for Chart & Query
            In the “DataSources”
Find the steps in the image
Find the sub sequent image for  Parameters applying for chart & Query.

do same as shown in images.

Step 5:
Save the dashboard and then Click on “Preview” button.
See the images below for sample out put with date input controls.
Preview of the dashboard with out any input controls selection

Preview of the dashboard after selecting date input controls.. find the images below one by one.

Find the image for observing whether the chart becomes dynamic or not with different date input controls.

That’s it.. You are done with date input controls on dashboard.

Jaspersoft CE v/s EE / Having Jaspersoft EE functionality in Jaspersoft CE

Jaspersoft CE versus EE / Having Jaspersoft EE functionality in Jaspersoft CE

 

Jaspersoft is world’s leading Open source BI software with more than 1.75 million download and usage. It comes in two variants, one is the community edition which is free and the other is the enterprise edition. Via this blog, we would try to understand the differences between the CE and EE. Also, we will make an attempt to understand and have Jaspersoft Enterprise Edition functionality in Jaspersoft Community Edition. Many a times, customers (esp startups and SMEs) dont have the budget or requirement to go for a full license, but they want full functionality which are present in EE, for them we have also discussed possible way outs as well.

 

a) Report Designer: Jaspersoft is known for its pixel perfect reports. This is created by iReport designer (free and open source). This tool helps in creation of complex reports with charts, graphs, tabular data, cross tabs, images etc. These reports can further be downloaded in different formats.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

b) Adhoc Report designer: Very beneficial for Business user, it gives a pivot kind of functionality, thus an end user can himself drag and drop the fields and create his own report on the fly. He can see this report as either a tabular data, or visualize it in different formats, save this and download this.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: In order to use adhoc reporting feature in Jaspersoft Community edition (CE), we can use a best of breed kind of solution. We can use Pentaho SAIKU plugin (its free), using this plugin for adhoc reporting, we can call it inside liferay and have adhoc reporting functionality in Jaspersoft as well.

 

c) Reporting Engine: Jasper reporting engine which is java based is again free and open source. It can fetch data from any kind of data source and provide picture perfect reports which can be seen, download (in different formats), printed.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

d) Dashboards: A dashboard can be a mix and match of reports, data visualizations, web APIs data, interactive parameters etc. Dashboard functionality is present only in the Jaspersoft EE

 

Availability:  Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: For implementing dashboard inside Jaspersoft Community Edition (Jaspersoft CE), we will have to go ahead with a best of breed solution. What we can do is for dashboards, we can use Pentaho CDE and CDF components. For representation of that, we can either use liferay or Alfresco.

Another alternative is we can call multiple instances of ireports inside liferay, thus creating a dashboard. For this a portlet has to be developed in liferay.

 

e) Interactive report viewing: This lets user to see the columns and perform functions like filter, arrange, sort etc.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

f) In-memory analysis: In memory basically helps in analyzing, seeing reports dashboards analysis etc on real-time and at a very high speed because it directly dumps all the information in its in-memory and doesn’t access db again and again for any requirement. This results in very high speed and throughput.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: Again, to implement In-memory analytics in Jaspersoft Community edition, we will have to use a best of breed solution. We can go with the Pentaho SAIKU plugin (which is free of cost) and liferay usage for representation

 

g) Server Repository: Place to store reports, dashboards, views, mashups, analytics, user profiles etc.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

h) Report Scheduling / Report Bursting: Email scheduling of the reports (could be time or trigger based).

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

i) Support: Jaspersoft is having multiple level of supports like standard support, premium support but it is only available to enterprise edition customers.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: Jaspersoft CE customer, can either will entirely depend on community support or they can come to companies like us (Helical IT Solutions), which have expertise on Jaspersoft and can help out on all the issues.

 

 

j) Mobile Business Intelligence: – Native app supporting iOS and Android platform. Touch-based browser support for iPad. iOS and Android SDK for embedding BI in native mobile app.

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

k) Metadata Layer: Metadata basically means data about data content. Via metadata layer, we create another layer containing information about the database, hence thus implementing data level security.

 

Availability:    Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: For implementing metadata layer in Jaspersoft CE, what we can do is we can use OLAP server (which is present in CE – community edition) to design metadata layer along with implementing role and user based security.

 

l) User access to reports/dashboards and other things: This facility is again present in both the versions of Jaspersoft.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

m) Data Virtualization: This basically means integrating multiple data sources into a metadata view, and then doing BI work on it. This step reduces the work this involved in ETL.

 

Availability:  Jaspersoft CE: No

Jaspersoft EE: Yes

 

 Alternatives: The entire work of data virtualization can be done by writing ETL jobs and stored procedures. For ETL, Talend or Kettle either of the tool can be used.

n) Data Integration (ETL): ETL stands for extract transform and load. Extract means extracting data from different dbs (big data, columnary databases, graphical databases etc), web APIs etc. After extracting, transform the same according to the business rules and finally load it into the target system which could be a database, data warehouse, data mart etc. Jaspersoft has ETL tool by the name of Talend (also known as Jasper ETL).

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

o) Interactive Visualizations: This basically means very interactive HTML5 charts with animations, hover information, interactivity in terms of selection, zoom in zoom out, interactive legends etc.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: These kind of interactive visualizations are not present in Jaspersoft community edition. For enabling that, what can be done is we can design plugin designed like jcharts and openflash (for openflash plugins are already available). One of the very famous example is Pentaho Community edition having interactive charts by CCC components (community chart components). We can also use CCC and thus have best of breed solution.

 

p) OLAP Server: OLAP (online analytical processing) helps in analyzing large amount of data using querying, visualizations, multi lever analysis, slice and dice, filtering etc. OLAP helps users to understand multi-dimensional data from multiple-view point. It consists of mainly three functions – consolidation, drill down, slicing & dicing.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

q) Multi-tenancy: This allows single instance support multiple customers, with each customer having his own userid password.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: Multi-tenancy can be implemented in Jaspersoft Community Edition (CE) using Liferay portlet.

 

r) License: Jaspersoft CE has General public license whereas the license is having commercial license. Hence, if a client is Jaspersoft EE client, he does not need to open up his source code to the public, which is not the case with Jaspersoft CE clients.
