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. these modules are available from cpan.

if you intend to run the regression tests (recommended), you will also need to prepare an empty database before starting the installation procedure.
