Description

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 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 the working RDBMS programmers a map of the terra incognita they will
face?if they want to grow.
