New DB2 for iSeries Redbooks
The first new redbook covers stored procedures, triggers, and user-defined functions, and it is called, appropriately enough, Stored Procedures, Triggers, and User-Defined Functions on DB2 Universal Database for iSeries. This redbook covers some of the announced features for stored procedures, triggers, and UDFs in V5R1, V5R2, V5R3, and V5R4. This redbook offers suggestions, guidelines, and practical examples on how to effectively develop DB2 for iSeries stored procedures, triggers, and UDFs.
The Ins and Outs of XML and DB2 for i5/OS is the second of the new DB2 for iSeries redbooks. As you might guess, this redbook focuses on XML. It covers the challenges of representing XML hierarchies in a relational DBMS, as well as provides an in-depth explanation of the most popular approaches to bridge the hierarchy / relational dilemma.
Also, if you are interested in XML and DB2 you might also want to check out the recently-published DB2 9 pureXML Guide, which covers pureXML in DB2 for LUW.
