=head1 NAME ObjStore - Perl Extension For C OODBMS =head1 SYNOPSIS Like perl? Sick of SQL? Ready to try something new? This extension implements databases that look exactly like normal perl. The same can also be extended with arbitrary C++ objects (!). =head1 PREREQUISITES - ObjectStore 5.1 (see http://www.odi.com; evaluations are available!) - Perl 5.005 (5.004_04 might still work too) - Tree::Fat perl extension - ExtUtils::ExCxx (only needed on Digital UNIX, HP (5.x), OS/2 (3.x), or MS Windows NT/95; send email) See http://www.perl.com/CPAN/authors/id/JPRIT/ ! =head1 IS THIS PERL ONLY?

This is an advantage for applications that require the highest level of performance. However, there is nothing that I do with databases that needs such extreme degrees of optimization. Rather, I value ease of use and ease of change slightly above raw performance. When I designed the perl interface, I was always trying to optimize for these priorities. For example, I decided to start with a generic schema. This gained some big advantages: All perl databases are compatible. All perl databases will never I schema evolution. All perl databases can be edited with a standard perl shell. Even so, ObjectStore's recent support of DLL schemas allows the seemless integration of application specific C++ objects. For example, a code generator is available (L) that creates optimized records (ordered, typed list of fields like a C structure). Recently, I also got PDL properly integrated (L). PDL is a perl extension for matrix mathematics. I believe the uncommon ability to integrate with everything at the lowest level (C) while still remaining maximally generic is unique among database architectures. =head1 R!CENT CHANGES ** 11-05-98 RELEASE 1.50 - Fixed order of PUTBACK/POPSTACK. ** 11-04-98 RELEASE 1.49 - Stargate reengineering for ObjStore::Lib::PDL. - MIN_PERL_DEFINE clean up for 5.005_53. - Various API improvements.
