BeanKeeper 2.6.0 (Default branch)
BeanKeeper (formerly Simple Persistence for Java) is a full featured, powerful object/relational persistence and query library. It has a unique philosophy of simpleness and ease of use: it does not require config files, annotations, code generation, code "enhancing", or any kind of tools to be used. It handles simple Java beans (or POJOs) and its query service returns lists. Despite its simpleness, under the hood the library takes care of all the necessary logic: transaction visibility, result list paging, keys and ids, table creation/modification, class relations, inheritance/polymorphism, case sensitiveness, and much more. It currently supports: Oracle, HSQLDB, MySQL, and PostgreSQL. License: GNU Lesser General Public License (LGPL) Changes:
Java-cup was replaced with JavaCC for parser generation. JUnit was replaced with TestNG. Ant was replaced by Maven2. One memory leak bug was fixed. The code was cleaned up to pass the checkstyle audit. Image

NAME

       Tangram::Driver::Pg - Orthogonal Object Persistence in PostgreSQL databases

SYNOPSIS

	  use Tangram;
	  use Tangram::Driver::Pg;

	  $schema = Tangram::Driver::Pg->schema( $hashref );

	  Tangram::Driver::Pg->deploy($schema, $dbh);

	  $storage = Tangram::Driver::Pg->connect( $schema,
	     $data_source, $username, $password );

	  $storage->disconnect();

	  Tangram::Driver::Pg->retreat($schema, $dbh);

DESCRIPTION

       This is the entry point in the Pg-specific object-relational persistence backend.

       This module performs the following:

METHODS

       This backend does not add any methods; for a description of available methods, see Tangram::Relational.

ERRATA

       Tangram::Type::Dump::Storable objects are first encoded with MIME::Base64, because Tangram does not currently have an easy mechanism for
       calling "DBI->bind_param()" at the appropriate time to flag the column as binary.

       Tangram::Type::Dump::Perl objects are stored as "BYTEA" columns, which as of DBD::Pg 1.31, also do not get correctly escaped by the DBD
       driver.	This also affects the (as-yet not fully functional) Tangram::Type::Dump::YAML back-end, which might put "" characters into a YAML
       document.

       It is recommended to use the "storable" type with Tangram::Type::Dump::Any for this reason.
