We started the chapter with the basic components of the PowerCenter Designer screen, that is, Source Analyzer, Target Designer, Transformation Developer, Mapplet Designer, and Mapping Designer. You then learned to work on different types of sources, which included flat files (delimited files and fixed-width files) and relational databases. Similarly, we worked on different types of targets. We also worked on the import and create functionalities of sources and targets. Later in the chapter, you saw how to preview the data. The last and most important aspect that you learned in this chapter was how to create mappings using sources and targets.

The Informatica PowerCenter Designer screen, of course, cannot be that simple. Moving ahead, in the next chapter, we will see the advanced concepts of the designer screen. There are a lot of high-level functionalities that are added in the designer window to help better and faster processing.

In the next chapter, you will see how to process the data by managing the constraints in the database. You will also see the utility to debug the mapping, which will help in finding any errors, and will study the concept of the reusable functionality of transformations and mapping.
