Joe Celko's Analytics and OLAP in SQL
Before SQL programmers could begin working with OLTP (On-Line Transaction Processing) systems, they had to unlearn procedural, record-oriented programming before moving on to SQLâs declarative, set-oriented programming. This book covers the next step in your growth. OLAP (On-Line 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 faceâif they want to grow.
Virtually everyone who has bought and liked a book by Joe Celko (and there are over 75,000 of those people) and the many tens of thousands more who have been helped by his advice in magazine columns or on newsgroups are part of the market for this book. Mostly the market includes experienced SQL programmers who have worked with OLTP systems who need to learn techniques--and even some tricks--that they can use in an OLAP situation.
