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!

Automating processes

The jobs we have described in this chapter so far are typical integration jobs, mapping, and transforming data to comply with an integration specification from standalone systems. However, we can also use the Studio to automate processes that would often be undertaken manually. Let's look at a couple of examples.

E-mailing daily sales

The management of Delightful Dresses wants to know the value of sales from the website on a daily basis. This might be done manually by an employee running a report, downloading it onto their computer, and then e-mailing it to an e-mail group. There are a specific set of steps to follow and they don't vary from day to day, an ideal process to automate.

This can be achieved directly in the Studio and the high-level job schematic is shown in the following screenshot:

As you can observe, the job is relatively simple. Perform the following steps:

  1. The Studio runs a SQL query against the website database.

  2. The data output is written to an Excel file...
