Part III. DB2 In-Depth
On the surface, DB2 looks simple. Pump in SQL, and DB2 throws back data. But for all the external simplicity of DB2, at its heart is a complex network of intricate code and communicating address spaces. How does all this stuff work?
Most people do not bother to find out. This is a pity. When programmers, analysts, and DBAs have the additional knowledge of the inner workings of DB2, application development is smoother, the code is more efficient, and problem resolution is faster.
The chapters in this section—Chapters 18–23—will expose you to data sharing, locking, query optimization, the DB2 Catalog, and how to use DB2 with CICS, IMS, and TSO.
So venture on, brave soul, and explore DB2 in-depth.
