Object-relational databases offer immense power -- but many database professionals have failed to use it, because doing so required them to write their own DataBlade extensions. This book presents a breakthrough solution: bladelets. Created by a team of Informix' leading DataBlade experts, bladelets serve as building blocks, bringing Informix Dynamic Server 9.x ORDBMS power to bear on a wide range of business problems, while requiring far less original programming. The book covers ten bladelets in detail, with open source code for all of them provided on CD-ROM. These bladelets will help developers solve hierarchical problems; extend SQL to support temporal data management; access external files through SQL, use SQL as a data type, overcome database portability problems, work with vtables, streamline text manipulation, and address many other common challenges. Whether you use them "as is," or as the model for your own DataBlades, these bladelets can dramatically improve the performance, value, and time-to-market of your very next database application.
JACQUES ROY, one of Informix' leading evangelists on database extensibility, is author of Informix Dynamic Server.2000: Server-Side Programming in C (Prentice Hall PTR). WILLIAM W. WHITE, senior engineer at Informix, works with DataBlade Partners and internal engineers on projects related to database extensibility, and is a frequent contributor to the Informix Developers Network (IDN). JEAN ANDERSON is a Senior Engineer in Informix Datablade Partner Engineering specializing in helping developers implement server extensions. She has authored many technical notes and projects at IDN's DataBlade Corner. PAUL G. BROWN of Informix Labs is a prominent object-relational evangelist and author of Object-Relational Database Development, a Plumber's Guide (Prentice Hall PTR).
