Getting Started with Talend Open Studio for Data Integration

By: Jonathan Bowen

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!

Sorting data

Our next data processing example will look at sorting data. Let's dive straight in:

  1. Create a new job and name it Sorting.

  2. We will use the currencies data file that we used previously in this example, so from the Repository Metadata drag the currencies delimited file onto the Job Designer. Select tFileInputDelimited from the pop-up window.

  3. From the Palette, search for delimited and drop a tFileOutputDelimited component onto the Job Designer. Now do a search for sort and drop a tSortRow component between the two delimited components.

  4. Right-click on the currencies delimited input and, using Row | Main, connect it to the sort component. Similarly, right-click on the sort component and use Row | Main to connect it to the delimited output component.

  5. In the Criteria box of the tSortRow component, click on + to add a row—some default values will be shown. The criteria we enter here will determine how the output is sorted. Let's leave the Schema column value as country, but change the sort...
