Currently for data integration jobs and transformation,user uses Kettle client for performing ETL operations using Spoon GUI.
My question is whether there is a browser based functionality available for Kettle where user can design tranformations & do job integration in the browser itself instead of using desktop PDI application?
NO there is no such functionality available right now.

Based on Pentaho guideline (https://help.pentaho.com/Documentation/8.2/Setup/Installation/Archive/MySQL_Repository) I successfully converted pentaho File based repository to MySQL database repository.
Now does anyone have any idea how MySQL repository store the data in database? It means If create new folder, new dashboard or new connection then how pentaho store this data in mysql database. Also need to know which tables is used for which purpose of data store.
Default created attached schema and tables based on mysql pentaho repository.
Please Provide any inputs or any reference material for same?
Pentaho's repository comprises three third party technologies: Jackrabbit, Hibernate, and Quartz. Reports/Jobs/Transformations and any other artifacts stored inside the Pentaho Server are generally stored in Jackrabbit. Scheduling info and triggers are stored in Quartz. And diagnostic info is stored in Hibernate (such as who accessed what reports, how long a report took to run, etc.).
None of this info is designed to be human readable directly out of the database tables. These are sort of "black box" technologies. These are third party technologies that Pentaho simply leverages for its repository functions. If you have additional questions, I'd recommend checking out the technologies themselves on their project pages.
I've just downloaded Pentaho Data Integration Community (pdi-ce-6.1.0.1-196) a.k.a. Kettle, with the goal of designing an ETL routine to make nightly migrations from MongoDB scheme into PostgreSQL.
I couldn't achieve the very first task: create a MongoDB connection. MongoDB is not listed as a Connection Type in the New Connection dialog, so I chose Generic database. Then, I failed to find anything related to MongoDB in the Custom Driver Class Name field required for the generic connection.
Is it possible that the installation/configuration went wrong with Kettle? I remember that I had to kill the first startup because it hanged forever.
Or does PDI-CE lacks some component that I must get somewhere else?
PDI handles Mongodb differently than other databases.
If working on a transformation (vs a job), go to the "Big Data" group of steps and there are two steps - one for MongoDB Input and one for MongoDB Output.
Within those steps you specify the connection information to your database.
Hope that helps,
Mark
P.S. There is also a "MongoDB Delete" in the marketplace that comes in useful when deleting data from collections.
We are using Microsoft Azure USQL for database testing.
Can anyone please provide the ODBC/JDBC connection details for USQL?
U-SQL is currently only available in the Azure Data Lake in a batch job form factor. This means that there is currently no ODBC/JDBC connectivity available since it is not giving you the ability to pass results directly to the providers.
So the programmatic way to submit U-SQL jobs is to use any of the available SDKs (Java, C#, Powershell, node.js, Python once available) to submit the job and then download the generated files as results.
We are working on an interactive form factor for U-SQL as well, but that is still a bit out.
I have been working with Pentaho for the last few days. I have been able to setup the Pentaho Report Designer to generate a sample report by follow their documentation. Then I follow this article http://www.robertomarchetto.com/www/how_to_use_pentaho_report_designer_tutorial and managed to export the report to Pentaho BI server.
All I don't understand is Pentaho workflow. What should be the process I should follow which means what's the purpose of exporting the export to Pentaho BI server? Why there is a Data Integration tool? Why there is a BI sever when I can export the report from the Designer tool?
Requirement
All I want to do is retrieve the data from the MYSQL DB. Put them into a data-mart. Then from the data-mart generate a report.(According to what I have read, creating a data mart is the efficient way).
How can I get it done?
Pentaho Data Integration can be used to make this report generation automated.
In report designer you will be passing a parameter or set of parameters to generate a single report output.
With Data integration you can generate the reports for different set of parameters. for eg: if reports are generated on daily basis, we can make it automated for the whole month, so that there is no need of generating reports daily and manually.
And using the Pentaho Business Intelligence server we can make all these operations scheduled.
To generate Data/Table(Fact tables/dimension table) in MYSQL DB From difference source like files/different DB - Data Integration tool comes in to picture .
To create Schema on top of Fact tables - Mondrian tool
To handle user/roles on top of created cubes -Meta data editor
To create simple reports on top of small tables - Report Designer
For sequential Execution (at a go) usage of DI jobs/transformation , Reports, Java script - Design Studio

The Data Integration tool is mostly for ETL, it's a separate tool and you can ignore it unless you are doing complex analysis of data from multiple dissimilar data sources. You don't need to 'export' reports to the pentaho server, you can write them directly to a directory then refresh the repository from inside the Pentaho web application. Exporting them is just one workflow technique.
You're going to find that there are about a dozen ways to do any one thing with Pentaho. For instance I use the CDA datasources with my reports vice placing the sql code inside my report. Alternatively you can link up to a Data Integration server to execute the Data Integration scripts to view a result set.
Just to answer your datamart question. In general a datamart should probably be supported by either the Data Integration tool (depending on your situation I don't exactly recommend this) or database functions/replication streams (recommended).
Just to hazard a guess, it sounds like someone tossed you a project saying: We need a BI system, here's the database where the data is stored, here are the reports we're already getting. X looked at Pentaho and liked it. You should use that.
First thing you need to do is understand the shape of the data, volume, tables, interrelations. Figure out what the real questions they want to answer are. Determine whether they need real time reporting, etc..etc. Just getting the datamart together itself, if you even need one, can take quite awhile. I think you may have jumped the gun on Pentaho itself.

We have a couple of jobs and transformations in pentaho that I'd like to call remotely from a script. Is there a way to call a job remotely? Can I also pass it variables?
Pentaho Data Integration does support remote execution. You're looking for a component called Carte.
Here's the docs:
