Earlier, we discussed the roles of data sets and data adapters—specifically, that a data set represents a cache of data that has a similar structure to that of a relational database, and that a data adapter acts as a bridge between a data source and a data set. In this section, we’ll examine in more detail how to work with and manage data sets, and the role the data adapter plays. Specifically, we’ll look at the following topics:
