Getting Started with Talend Open Studio for Data Integration

Overview of this book

Talend Open Studio for Data Integration (TOS) is an open source graphical development environment for creating custom integrations between systems. It comes with over 600 pre-built connectors that make it quick and easy to connect databases, transform files, load data, move, copy and rename files and connect individual components in order to define complex integration processes. "Getting Started with Talend Open Studio for Data Integration" illustrates common uses and scenarios in a simple, practical manner and, building on knowledge as the book progresses, works towards more complex integration solutions. TOS is a code generator and so does a lot of the "heavy lifting"ù for you. As such, it is a suitable tool for experienced developers and non-developers alike. You'll start by learning how to construct some common integrations tasks ñ transforming files and extracting data from a database, for example. These building blocks form a "toolkit"ù of techniques that you will learn how to apply in many different situations. By the end of the book, once complex integrations will appear easy and you will be your organization's integration expert! Best of all, TOS makes integrating systems fun!

Summary


In this chapter, we explored the Studio processing components and how we can use them to modify the data flows between files, databases, and other start and end points through the use of filters, data sorts, and aggregations. We saw how we could group and un-group data with the Studio normalize and denormalize components. The Studio's tReplace component is a simple, but hugely useful addition to your toolkit and will undoubtedly find a place in many of your integration jobs. Finally, the ability to extract specific rows from a data flow through the tSampleRow component was reviewed and we will see examples later in the book where, when combined with a sorting component, this has some powerful applications.

When building integration jobs, you will commonly use the processing components in combination. For example, you might take a data flow from a database, filter out the records you want, then pass the data to a find and replace component, where you will substitute some values with...
