libsas is a Python library to take the pain out of using SaaS APIs. It provides an abstraction layer on top of various APIs, taking care of constructing the URLs, serializing parameters, and authentication. You just call Python methods and receive Python objects. It's like an ORM for SaaS.
SQL Construction Kit aims to provide a simple builder/factory pattern based approach to generating DML SQL for all popular RDBMS systems. Included builders are SelectBuilder, InsertBuilder, UpdateBuilder, and DeleteBuilder. It is much lighter weight than any of the ORM tools available, and is 100% Java. It is a complete re-factoring of code that has been in production use since 2001 (updated to use features of Java 6). Also included is a Facade patterned Database object that wraps a Datasource object. This provides an execution framework for the results of the Builder objects, which includes simplified transaction and batch management as well as the ability to transparently handle SQL exceptions in a default manner. The Database object also provides a simple object-oriented approach via wrappers around the database metadata.
Tephlon is an easy PHP persistence library. It has a highly modular OOP design and a no-SQL storage system. It stores any object or variable safely and tidily on disk for fast access. The API is meant to be easy and fast to learn. It features Java-style key-value maps, namespaces, easy Codeigniter integration, programmable lifetime of records, a multi-driver architecture, reliable and well-tested code, and easy incremental backup of data with SVN or GIT.
pg_greentrunk provides fundamental components of GreenTrunk, an interface protocol (API) for using a PostgreSQL database with Python. It provides an interface for implementations to use, and provides documentation in the form of Python modules to allow immediate access to object descriptions, even when inside a Python console.
StactiveRecord is a C++ library designed to make simple database use simple. It was inspired by Ruby on Rails' Active Record, however, no similar look, feel, or performance is guaranteed. It uses an object-relational mapping pattern to represent records as objects. It also provides persistent (basic) object relationships (one to many, many to many, one to one).
