Creating a Mapping with Fact and Dimension Tables

Creating a Mapping with Fact and Dimension Tables

In previous lessons, you used the Source Qualifier, Expression, Aggregator, and Lookup transformations in mappings. In this lesson, you learn how to use the following transformations:
  • Stored Procedure. Call a stored procedure and capture its return values.
  • Filter. Filter data that you do not need, such as discontinued items in the ITEMS table.
  • Sequence Generator. Generate unique IDs before inserting rows into the target.
You create a mapping that outputs data to a fact table and its dimension tables.
The following figure shows the mapping you create in this lesson:
The mapping contains several sources joined by one source qualifier and several targets. The source qualifier connects directly to two targets. It connects to a third target through a Filter transformation. It connects to a fourth target through a Stored Procedure transformation. An Update Strategy transformation also connects to the fourth target.
