Before SQL programmers could begin working with OLTP (online transaction processing) systems, they had to unlearn procedural, record-oriented programming before moving on to SQLs declarative, set-oriented programming. This book covers the next step in your growth. OLAP (online analytical processing), data warehousing and analytics involve seeing data in the aggregate and over time, not as single transactions. Once more it is time to unlearn what you were previously taught.
This book is not an in-depth look at particular subjects, but an overview of many subjects that will give the working RDBMS programmers a map of the terra incognita they will faceif they want to grow.
