Introduction


With transformations, you manipulate data in many ways: doing mathematical or logical operations, applying string functions, grouping by one or more columns, sorting, and much more. Besides transforming the data you already have, you may need to search and bring data from other sources. Let's look at some examples:

  • You have some product codes and you want to look for their descriptions in an Excel file

  • You have a value and want to get all products whose price is below that value from a database

  • You have some addresses and want to get the coordinates (latitude, longitude) for those locations from a web service

Searching for information in databases, text files, web services, and so on is a very common task and Kettle has several steps for doing it. In this chapter, you will learn about the different options.
