An Introductory Course (Pt. 1) (DB2 for the Cobol Programmer) - Tapa blanda

Reseña del editor

The trouble with most DB2 books is that they treat application programming as an afterthought, presenting it in a chapter or two at the end. So you go through most of the book trying to figure out how the DB2 information you're learning can be applied to your programs.But DB2 for the COBOL Programmer, Part 1 makes it easy for you to master the essentials of DB2 programming. Written from the programmer's point of view, it focuses right from the start on what you need to know to access and process DB2 data in your application programs using embedded SQL.You'll learn: -- the basics of how DB2 works so you can program more easily and logically-- how to design and code DB2 programs-- how to use basic error handling and data integrity techniques to protect DB2 data-- how to work with tables defined with referential integrity support-- how to use joins and unions to combine data from two or more tables-- how to use column functions to extract summary data from a table-- how to work with variable-length data and nulls-- how to develop DB2 programs interactively (using DB2I, a TSO facility) or in batch-- and more!Eleven complete programs -- with source code, structure chart, and sample input and output -- let you see clearly how the DB2 code you're learning fits into an actual program. And the examples are all realistic enough that they'll make handy references for you to use on the job every day. In fact, if you use them as models for your own programs, you'll save yourself hours of coding, testing and debugging.So get your copy of DB2, Part 1 Today. I think you'll be delighted at how quickly its programmer-based approach will have you writing DB2programs."I originally used your DB2 books as training material for embedded SQL using Oracle. From the programmer's perspective, embedded SQL is embedded SQL...so long as you adhere to the ANSI standard, the programmer really doesn't care what flavor of RDBM he will be using". -- J.O., Data Base Administrator, Jackson, MS
