The T2 module is a base for the refactoring of the now quite stable
|
|
Tangram Object-Relational mapper.
|
|
|
|
In a nutshell, it lets you store objects - which have to be described to a
|
|
similar level that you would describe a database to store them - into any
|
|
SQL store. Currently, this is tested on PostgreSQL, MySQL, Oracle and
|
|
Sybase a lot, though in general database-specific extensions to SQL, such
|
|
as triggers, stored procedures, etc are avoided. So, if DBI installs and
|
|
tests successfully with your database, there is a good chance that T2 will
|
|
work with it too.
|
|
|
|
The only current requirement is that objects that have tables associated
|
|
with them are implemented via hashes. You also have to be able to describe
|
|
all of the fields for those root objects. Individual fields of stored
|
|
objects may be arbitrarily complex.
|
|
|
|
If you are familiar with DBI, it is somewhat similar to bless'ing the
|
|
structures returned by $dbh->fetchrow_hashref, except that references and
|
|
collections to other objects in the store are loaded `on demand' (aka
|
|
Lazy-loading).
