By now, you’ve translated your business requirements into an SSAS cube. The next task in implementing your BI project is to execute an ETL solution from your detailed data map. As discussed in Chapter 7, data maps are used as a basis for beginning ETL design. In our experience, a good deal of the initial work on a BI project consists of ETL process design, development, and debugging. We assume that you’ve completed your data map and created a simple package or two using the Import and Export Wizard or by using the SSIS package template in BIDS. In this chapter, we’ll cover the following topics:
Considering common ETL package-design practices
Understanding control flow tasks
Understanding data flow transformations
Using the Dynamic Configuration Wizard and property expressions
KeywordsControl Flow Data Flow Precedence Constraint Design Surface Sample Package
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
