Spurred by IBM's success with DB2, thousands of new users are working with DB2 on OS/390 mainframes for the first time. Now, direct from IBM, there's an authoritative introductory guide to running DB2 in OS/390 environments. This book offers a practical, hands-on overview of everything new users need to know, from relational database and SQL fundamentals to basic design, administration, and application development. Now, new DB2 for OS/390 users have a single source for detailed introductions to every aspect of working with IBM's flagship database on mainframe platforms. The book reviews basic relational database concepts, SQL, the fundamentals of database design, the key tasks associated with day-to-day database administration in mainframe environments, application development, and more. Next, it introduces new users to a wide range of DB2's most sophisticated capabilities, including data sharing, distributed data, and Web access. For readers ready to go beyond the fundamentals, it also includes extensive cross-references to other IBM books and information resources.
For all developers, administrators, managers, and end users new to DB2 for OS/390 -- including those familiar with DB2 or other databases on other platforms, as well as those new to enterprise databases.
