Can fieldnames in a row duplicated in Pentaho? Does transformation allow filed duplication? The original field will have a duplicate name of the other field now.
How to use database connections from repository? Explain in brief the concept Pentaho Dashboard. Dashboards are the collection of various information objects on single page including diagrams, tables and textual information. The steps involved in Dashboard creation include Adding dashboard to the solution. Defining dashboard content.
Editing dashboards. Transformation logic can be shared using subtransformations, which provides seamless loading and transformation of variables enhancing efficiency and productivity of the system. Subtransformations can be called and reconfigured when required.
Explain the use of Pentaho reporting.
Pentaho reporting enables businesses to create structured and informative reports to easily access, format and deliver meaningful and important information to clients and customers. What is Pentaho Data Mining? Pentaho Data Mining refers to the Weka Project, which consists of a detailed tool set for machine learning and data mining. Weka is open source software for extracting large sers of information about users, clients and businesses.
It is built on Java programming. Take charge of your career by going through this professionally designed Pentaho Certifications.
Data Integration refers to passing of data from one type of systems to other within the same application. On the contrary, ETL is used to extract and access data from different sources. And transform it into other objects and tables.
Explain Hierarchy Flattening. It is just the construction of parent child relationships in a database. It is very nicely explained. At a minimum.
I would hope there is a significant uptake in use of such a technology. Google would love you.
This is really amazing information. I like to read this information. Thanks for sharing this wonderful information. Web designers in Bangalore Very Nice article Its found the best information about website design and development,..
Thank you for sharing the great information You provided very useful information in this article. I have read many articles in various sites but this article is giving in depth explanation about Pentaho Training. The first idea was to build it on top of KDE, the popular Unix desktop environment. Trolltech, the people behind Qt, the core UI library of KDE, had released database plans to create drivers for popular databases.
However, the lack of decent drivers for those databases drove Matt to change plans and use Java. He picked Java because he had some prior experience as he had written a Japanese Chess Shogi database program when Java 1.
After a year of development, the tool was capable of reading text files, reading from databases, writing to databases and it was very flexible. The code had grown unstructured, crashes occurred all too often, and it was hard to get something going with the Java graphic library used at that moment, the Abstract Window Toolkit AWT ; it looked bad and it was slow.
As for the library, Matt decided to start using the newly released Standard Widget Toolkit SWT , which helped solve part of the problem. As for the rest, Kettle was a complete mess.
It was time to ask for help. At various intervals over the next few years, Wim involved himself in the project, giving advices to Matt about good practices in Java programming. Listening to that advice meant performing massive amounts of code changes.
As a consequence, it was not unusual to spend weekends doing nothing but refactoring code and fixing thousands of errors because of that. But, bit by bit, things kept going in the right direction. At that same time, Matt also showed the results to his peers, colleagues, and other senior BI consultants to hear what they thought of Kettle.
That was how he got in touch with the Flemish Traffic Centre www. All of a sudden, he was being paid to deploy and improve Kettle to handle that job. The diversity of test cases at the traffic center helped to improve Kettle dramatically.
That was somewhere in and Kettle was by its version 1. While working at Flemish, Matt also posted messages on Javaforge www. He got a few reactions. Despite some of them being remarkably negative, most were positive. The most interesting response came from a nice guy called Jens Bleuel in Germany who asked if it was possible to integrate third-party software into Kettle.
Kettle didn't have a plugin architecture, so Jens' question made Matt think about a plugin system, and that was the main motivation for developing version 2. For various reasons including the birth of Matt's son Sam and a lot of consultancy work, it took around a year to release Kettle version 2.
It was a fairly complete release with advanced support for slowly changing dimensions and junk dimensions Chapter 9 explains those concepts , ability to connect to thirteen different databases, and the most important fact being support for plugins.
Matt contacted Jens to let him know the news and Jens was really interested. There was a lot of excitement, and they agreed to start promoting the sales of Kettle from the Kettle.
Those were days of improvements, requests, people interested in the project. However, it became too much to handle. Doing development and sales all by themselves was no fun after a while. As such, Matt thought about open sourcing Kettle early in and by late summer he made his decision. Jens and Proratio didn't mind and the decision was final. When they finally open sourced Kettle on December , the response was massive.
The downloadable package put up on Javaforge got downloaded around times during first week only. The news got spread all over the world pretty quickly. What followed was a flood of messages, both private and on the forum.
At its peak in March , Matt got over messages a day concerning Kettle. In no time, he was answering questions like crazy, allowing people to join the development team and working as a consultant at the same time. Added to this, the birth of his daughter Hannelore in February was too much to deal with.
Fortunately, good times came. They had selected Enhydra Octopus, a Java-based ETL software, but they didn't have a strong reliance on a specific tool. While Jens was evaluating all sorts of open source BI packages, he came across that thread. Matt replied immediately persuading people at Pentaho to consider including Kettle.
And he must be convincing because the answer came quickly and was positive. Later on, Matt came in touch with one of the other Pentaho founders, Richard Daley, who offered him a job.
That allowed Matt to focus full-time on Kettle. Four years later, he's still happily working for Pentaho as chief architect for data integration, doing the best effort to deliver Kettle 4.
