We started the chapter with the debugger, which helps you debug the errors in your mapping. Using the debugger, you can pinpoint the error in your mapping using which you can easily resolve issues. Next, we discussed the reusable transformation that allows you to reuse the transformation across mappings. Reusable transformations are very important, as they save the time and effort required to recreate the same transformations.

Moving on, we talked about mapplets, which allow you to reuse groups of transformations that make your mapping simpler by replacing multiple transformations with a single component. Also, mapplets save your time and effort by allowing you to reuse existing components. Next in the line was the target load plan using which you can set the priority of loading the target tables in a single mapping. This is useful while loading the data and maintaining the constraints. We also saw some details about the parameters and variables that we will discuss in more details...
