Programming the Perl DBI: Database Programming with perlby Alligator Descartes and Tim Bunce
Synopses & Reviews
One of the greatest strengths of the Perl programming language is its ability to manipulate large amounts of data. Database programming is therefore a natural fit for Perl, not only for business applications but also for CGI-based web and intranet applications.
The primary interface for database programming in Perl is DBI. DBI is a database-independent package that provides a consistent set of routines regardless of what database product you use--Oracle, Sybase, Ingres, Informix, you name it. The design of DBI is to separate the actual database drivers (DBDs) from the programmer's API, so any DBI program can work with any database, or even with multiple databases by different vendors simultaneously.
Programming the Perl DBI is coauthored by Alligator Descartes, one of the most active members of the DBI community, and by Tim Bunce, the inventor of DBI. For the uninitiated, the book explains the architecture of DBI and shows you how to write DBI-based programs. For the experienced DBI dabbler, this book reveals DBI's nuances and the peculiarities of each individual DBD.
The book includes:
This is the definitive book for database programming in Perl.
Book News Annotation:
"The DBI is a database interface module for Perl. It defines a set of methods, variables and conventions that provide a consistent database interface independent of the actual database being used", explains Bunce, the architect and inventor of DBI. He and Descartes, one of the most active members of the DBI community, explain the architecture of DBI and show how to write DBI-based programs. For the DBI expert, they cover the nuances and peculiarities of each individual database driver. The basics of databases are well-covered, but some experience programming with Perl is assumed.
