Tangram - Orthogonal Object Persistence in Relational Databases
Tangram is an object-relational mapper. It makes objects persist in relational databases, and provides powerful facilities for retrieving and filtering them. Tangram fully supports object-oriented programming, including polymorphism, multiple inheritance and collections. It does so in an orthogonal fashion, that is, it doesn't require your classes to implement support functions nor inherit from a utility class.
Tangram is known to run in the following environments, however, Tangram uses standard SQL and should be usable with any SQL-83 compliant database.
Note that some functions (e.g. transactions and subselects) may not be available in some environments. This is reported during the test suite.
Perl 5.00503
Set::Object 1.03
DBI 1.14
DBD::mysql 2.0402
DBD::Oracle 1.06
DBD::Sybase 0.21
DBD::Pg 0.93
