README for Tangram 2.10_01 ~~~~~~~~~~~~~~~~~~~~~~~~~~ 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 builds upon DBI, so you'll need to install DBI and at least one DBD driver if that is not done already. You will also need Set::Object, Scalar::Util, and Data::Lazy 0.6. These modules are available from CPAN, though currently Data::Lazy 0.6 has not been indexed, as the namespace hasn't been handed over - this will probably need to be installed manually. If you intend to run the regression tests (recommended), you will also need to prepare an empty database before starting the installation procedure, and have Test::More installed.
