The Data page, as shown in
Figure 3‑1, is divided into three areas: Databases, Files, and Options. Databases and Files are places where you define the connections to the data sources. Options is the place where you define a load process. A load process consists of options that determine the way the load process runs, and transactions. A load transaction describes the data mappings between the input data and the tables in the target database. A load process may contain multiple transactions.
