Now let’s put the pieces together by creating a data flow. The Data Flow organizes and encapsulates one data transformation and the source tables and columns used in the transformation to produce the target data. To create a data flow, click on the Data Lineage tab on the bottom of the Explorer pane (as shown in Figure 12.11).
