NAME

Tangram - Orthogonal Object Persistence in Relational Databases

DESCRIPTION

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.

COMPATIBILITY

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 1.02

  • DBI 1.14

  • DBD::mysql 2.0402

  • DBD::Oracle 1.06

  • DBD::Sybase 0.21

  • DBD::Pg 0.93
