MDX from a SQL Viewpoint; 18.1 MDX SELECT Statement18.2 Hierarchical NavigationBefore SQL programmers could begin working with OLTP (On-Line Transaction Processing) systems, they had to unlearn procedural, record-oriented programming before moving on to SQL's 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 theMorgan Kaufmann series in data management systems.Joe Celko's Analytics & OLAP in SQLAnalytics and OLAP in SQLOLAP technologySQL (Computer program language)OLAP technology.SQL (Computer program language)005.7585Celko Joe627493MiAaPQMiAaPQMiAaPQBOOK9910784650703321Joe Celko's analytics and OLAP in SQL1212754UNINA
