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!

Transforming CSV to XML

Working the other way around, we will now transform a simple CSV file into an XML format. Again, this is a common integration scenario, where, for example, data needs to move from a spreadsheet to a format suitable for loading into another application via its native API.

Start by creating a new job in the Chapter3 folder and call it CSV2XML. We're going to use the CSV output from our previous task as an input file this time, so take a copy of catalogue-out.csv from your DataOut folder and drop it into the DataIn folder. To avoid confusion, let's rename this to csv2xml-catalogue.csv.

As in the previous example, we'll start by declaring the metadata for the input file before completing the main configuration of the job. Perform the following steps:

  1. In the Metadata section of the Repository window, right-click on File delimited and select Create file delimited. The metadata wizard window will appear. Enter csv_catalogue into the Name field and click on Next:

  2. In step 2...
