Db2

This book covers everything a reader needs to know to take and pass the DB2 10.5 Fundamentals for LUW certification exam.

Understand the DDL and DML operations on DB2.

Paul Conte, a leading DB2/400 authority with extensive application development experience, provides easy-to-follow instruction in the proper way to create efficient, flexible databases on the AS/400. His explanations and advice assure that you'll handle your design and coding challenges with confidence and professional-level techniques. This book provides complete coverage of both DDS, the traditional approach to defining DB2/400 files, and of SQL/400, the industry-standard database language that is IBM's strategic language for the future of DB2/400. With this text, you can be sure of handling not only existing application databases, but also developing new SQL/400 databases.

DB2® 10 can reduce the total DB2 CPU demand from 5-20% when you take advantage of all the enhancements. Many CPU reductions are built in directly to DB2, requiring no application changes. Some enhancements are implemented through normal DB2 activities through rebinding, restructuring database definitions, improving applications, and utility processing. The CPU demand reduction features have the potential to provide significant total cost of ownership savings based on the application mix and transaction types.

IBM® DB2® 10 for z/OS® provided a strong performance improvement that drove great value for IBM clients. DB2 11 for z/OS continues the trend by focusing on further CPU savings and performance improvement through innovations within DB2 and the synergy with IBM System z® hardware and software. Most of CPU reductions are built in directly to DB2, requiring no application changes. Enhancements often take effect after the REBIND in the case of static applications, while some enhancements require user actions such as Data Definition Language (DDL) updates.
