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.

SQL for DB2 ISBN: 978-1-58304-123-9 This focused, comprehensive textbook provides start-to-finish coverage of SQL for DB2. Whether youre a college student studying SQL for DB2 for the first time or a professional developer who needs to learn SQL for DB2, this book covers all the basics necessary for success. The purpose of any database book is to learn how to develop databases effectively and precisely without the need for a lot of complicated jargon. This book delivers on that promise by focusing on the skill set necessary to develop well-designed DB2 databases. SQL for DB2 covers the core requirements of a traditional database course. Topics are presented in an accessible, easy-to-learn manner with numerous examples and tips. End-of-chapter materials include a chapter summary, list of key terms, and hands-on exercises that put the concepts to work. SQL for DB2 builds on the foundation of its widely acclaimed predecessor, SQL/400 Developers Guide, to provide an up-to-date introduction to SQL for DB2 for todays students and professionals. All chapters have been refreshed, with improved organization throughout. Examples have been updated, and new material has been added. This new edition includes: New chapters introducing DB2 and System i Navigator Expanded coverage of single- and multiple-table queries Expanded coverage of updating databases with SQL An expanded discussion of normalization Table of Contents Chapter 1 Introduction to DB2 Chapter 2 Introduction to SQL Chapter 3 Single-Table Queries Chapter 4 Introduction to Data Modeling and Database Design Chapter 5 Logical Data Modeling Chapter 6 Entity Relationship Diagram Chapter 7 Normalization Chapter 8 Physical Database Design Chapter 9 Database Constraints Chapter 10 Multiple Table Queries Chapter 11 Views and Indexes Chapter 12 Updating Tables Chapter 13 Static and Dynamic Embedded Statements Chapter 14 SQL Cursors and Result Sets Chapter 15 The Create SQL Program Command Chapter 16 Using SQL in RPG Programs Chapter 17 Triggers Chapter 18 Additional SQL Topics Chapter 19 Database Security and Grant and Revoke Statements

Improve the performance of relational databases with indexes designed for today's hardware Over the last few years, hardware and software have advanced beyond all recognition, so it's hardly surprising that relational database performance now receives much less attention. Unfortunately, the reality is that the improved hardware hasn't kept pace with the ever-increasing quantity of data processed today. Although disk packing densities have increased enormously, making storage costs extremely low and sequential read very fast, random reads are still painfully slow. Many of the old design recommendations are therefore no longer valid-the optimal point of indexing has come a long way. Consequently many of the old problems haven't actually gone away-they have simply changed their appearance. This book provides an easy but effective approach to the design of indexes and tables. Using lots of examples and case studies, the authors describe how the DB2, Oracle, and SQL Server optimizers determine how to access data, and how CPU and response times for the resulting access paths can be quickly estimated. This enables comparisons to be made of the various designs, and helps you choose available choices for the most appropriate design. This book is intended for anyone who wants to understand the issues of SQL performance or how to design tables and indexes effectively. With this title, readers with many years of experience of relational systems will be able to better grasp the implications that have been brought into play by the introduction of new hardware.

This is a guide designed to familiarize users with the DB2 standard while helping to optimize their use of the technology

Because databases often stay in production for decades, careful design is critical to making the database serve the needs of your users over years, and to avoid subtle errors or performance problems. In this book, C.J. Date, a leading exponent of relational databases, lays out the principles of good database design.
