Next Steps


Now that we have created a well-structured data warehouse database, we need to look at techniques for loading data from the source systems (covered in Chapter 4) and providing the information to users in a meaningful way (Chapter 5, "Building an Analysis Services Database").

Extending the Manufacturing Solution

We have really only scratched the surface of a full manufacturing data warehouse in this chapter, but remember that our goal is to achieve business value by focusing on delivering solutions that work, not by trying to model the entire business in one project. Based on the business problem described at the beginning of the chapter, we can include some new and interesting subject areas in the next versions of the data warehouse. One valuable area is to include quota or budget numbers so that users can track their performance against their targets. Also, we can look at adding information and calculations to support business objectives such as improving on-time deliveries.

Using the BI Development Studio to Generate the Data Warehouse

We will be using the BI Development Studio extensively in the next couple of chapters to develop the ETL process and to build some Analysis Services cubes. Instead of starting by manually building the data warehouse database as we did in this chapter, we could have started by defining our dimensions and facts at a logical level in the BI Development Studio, and then have generated the corresponding database tables.

This is a useful technique that enables you to use the BI Development Studio as a rapid prototyping tool to develop cubes and dimensions without an underlying data source. However, if you have experience in building data warehouse schemas by hand, you might find this approach somewhat limited in that you don't have complete control over the table structures and data types generated. BI developers who are not comfortable with building databases directly might find it much more intuitive, however, and then an experienced database designer could adjust the tables after they are generated.

To use the BI Development Studio in this way, you can create a new Analysis Services project with no data source, and then when adding dimensions, select the "Build without using a data source" option. After you have added attributes and hierarchies to the dimensions, you can select Generate Relational Schema from the Database menu to create the database.
