Spider Schema – a Bridge Between OLTP and OLAP?

Introduction As I mentioned in my article “OLAP for OLTP practitioners”, I am working on a project that needs to create an analytical database for on-line analytical processing (OLAP).

In OLAP, the main focus of the database itself is simply to store data for analysis; there is limited maintenance of data.
