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!

Writing data to a database


Having extracted data from a database, the obvious next step is to put it back in. In the real world, we might come across this scenario when we need to exchange data between one application and another. A common way of facilitating this exchange is to extract some data out of an application database A, write it to a file, then take the same file, and import it into an application database B. As different applications (often from different vendors) are unlikely to be integrated at the application or at the database level, this intermediate step provides a bridge between one application and another.

Tip

A word of caution before we proceed. In real-life scenarios, we should be cautious about writing data directly to a database. There is something quite final and irreversible about this sort of process and that is one of the reasons why so many applications have data import Application Programming Interfaces (APIs). APIs provide a measure of protection for the underlying...
