Book Description
If you are looking for a practical DB2 book that focuses on application programming, this is the book for you. Written from the programmer's point of view, it will quickly teach you what you need to know to access and process DB2 data in your COBOL programs using embedded SQL. This second edition has been thoroughly updated and expanded to make it even more valuable to the programmer who is slugging it out on the job. You will learn: the critical DB2 concepts that let you understand how DB2 works; the basic DB2 coding features you will use in every program you write; how to use version 4 enhancements like outer joins and explicit syntax for inner joins; how to work with column functions, scalar functions, and subqueries to manipulate data; how to use error handling techniques and ROLLBACK to protect DB2 data; why program efficiency is vital under DB2... and more.

Book Description
This is the latest edition of our classic COBOL book that has set the standard for structured design and coding since the mid-1970s. So if you want to learn how to write COBOL programs the way they're written in the best enterprise COBOL shops, this is the book for you. And when you're done learning from this book, it becomes the best reference you'll ever find for use on the job. Throughout the book, you will learn how to use COBOL on IBM mainframes because that's where 90% or more of all COBOL is running. But to work on a mainframe, you need to know more than just the COBOL language. That's why this book also shows you: how to use the ISPF editor for entering programs; how to use TSO/E and JCL to compile and test programs; how to use the AMS utility to work with VSAM files; how to use CICS for developing interactive COBOL programs; how to use DB2 for developing COBOL programs that handle database data; how to maintain legacy programs. If you want to learn COBOL for other platforms, this book will get you off to a good start because COBOL is a standard language. In fact, all of the COBOL that's presented in this book will also run on any other platform that has a COBOL compiler. Remember, though, that billions of lines of mainframe COBOL are currently in use, and those programs will keep programmers busy for many years to come.

Book Description
Database Design and Programming for DB2/400 is a comprehensive introduction to the design and implementation of application databases on IBM's AS/400. This clear and authoritative text teaches you the following essential skills: Coding Data Description Specifications (DDS) for physical and logical files, entering CL commands to create DB2/400 files from DDS, using field reference files, accessing database files from RPG IV, RPG/400, COBOL/400, and other AS/400 high-level languages, the Relational Database Model as a foundation for DB2/400 and database design, practical database design and data modeling, using SQL/400 to define and access database files, advanced DB2/400 features (including commitment control, the Open Query File command, database constraints, triggers, distributed database access, and others), database security, and data backup and recovery. 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. These skills will put you in the forefront of AS/400 application developers. Database Design and Programming for DB2/400 also provides an excellentintroduction to practical database design techniques. You get a solid introduction to the relational database model, which underlies the whole DB2/400 architecture and the SQL language. On that foundation, the book explains a step-by-step method of modeling an organization's database requirements and developing a design for the necessary database files. The text is designed for college-level courses and for independent study. Each chapter has numerous examples and exercises. The material is organized into four parts - DDS, database design, SQL, and advanced DB2/400 features - so you can focus on particular topics as needed. Appendices provide extensive reference material. You can use the book as your single DB2/400 resource, eliminating the need for many IBM manuals. You will find Database Design and Programming for DB2/400 immediately useful, whether you're just beginning to learn DB2/400 or you are an experienced developer. You will turn to this book time and time again for advice on the best way to design and program DB2/400 databases.

Book Description
The second part of IMS for the COBOL Programmer is for MVS programmers only. It teaches you how to handle online programs that access IMS databases and run under the data communications (DC) component of IMS. This book also covers Message Format Service (MFS). MFS acts as an interface between the format of messages at a terminal and the I/O formats in your programs. So you'll learn how to use MFS to create formatted screens that are easy for operators to use. And you'll learn what tasks you can handle through MFS instead of having to code for them in your DC programs.

Book Description
IMS database processing hasn't changed much since this book was published in 1986. So if you have to maintain an old program that uses DL/I, you won't find a better book than this one. In it, you'll learn: the DL/I database structure; COBOL for using DL/I; how to work with secondary indexing, logical databases, and databases with logical relationships; how to use recovery and restart features; and the basic considerations for coding DL/I programs with CICS or IMS DC.

Book Description
Once you know the basics of writing DB2 programs, there's still plenty to learn. So Part 2 of DB2 for the COBOL Programmer takes up where Part 1 leaves off, teaching you the advanced features you're going to want to know about as you continue working in DB2. Section 1 covers advanced DB2 features that you'll use from time to time in one program or another: -- how to handle data manipulation applications, especially those that involve time and date data -- how to use advanced error handling techniques -- how to handle dynamic SQL statements -- how to use the distributed data management capabilities of DB2 -- what you should know about concurrency and locking considerations to maintain the integrity of the data your programs are operating on (although DBAs control this, some of the options you specify in your programs can affect concurrency and locking efficiency) Section 2 shows you how to process DB2 tables in CICS programs. This section does not teach CICS itself (if you need CICS training, see our CICS books on pages 10 and 11). If you already know CICS, however, this section will teach you all you need to know to handle DB2 data in your CICS programs. Section 3 introduces you to the concepts and practices of DB2 data base administration, to enable you to define and create your own test tables. That's a skill that comes in handy both when you're testing programs and when you want to experiment interactively with SQL statements before you code the statements in a program. In short, knowing about these features will make you a more productive and professional programmer...even if you're not aspiring to be a DBA. Section 4 covers IBM's Query Management Facility(QMF), an interactive software product that lets users access data stored in DB2 tables. QMF is targeted to a wide range of users, from those with no data processing experience to experts. This section focuses on the basic QMF concepts and skills you can use as you develop your application programs. So don't wait to expand your DB2 skills. Get a copy of this book Today. I think you'll be delighted at how quickly you'll master the advanced features of DB2.
