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. 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 applicationsthe primary interface for database programming in perl is dbi. The dbi is the standard 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. The data returned from this module is passed back into the dbi module and from there it is returned to the perl program all the information that passes between the dbi and its drivers is standard perl datatypes thereby preserving the isolation of the dbi module from any knowledge of databases.
