Projects

DBI

The DBI module enables your Perl applications to access multiple database types transparently. You can connect to a large number of databases, including MySQL, MSSQL, Oracle, Informix, Sybase, ODBC etc. without having to know the different underlying interfaces of each. The API defined by DBI will work on all these database types and many more.

Propel

Propel is an object persistence and query service -- which means that Propel provides a system for storing objects to a database and a system for searching for and restoring the objects from the database. Propel enables you to perform complex queries and database manipulations without writing a single SQL clause.

zeoslib

The ZeosLib is a set of database components for MySQL, PostgreSQL, Interbase, Firebird, MS SQL, Sybase, Oracle and SQLite for Delphi, FreePascal/Lazarus, Kylix and C++ Builder. It connects to the chosen database using its native API, so no database middleware (eg. BDE) is needed.

dibi

dibi is tiny 'n' smart database abstraction layer for PHP 5. It is designed with simplicity in mind. dibi is free (released under the terms of the dibi license). You can use it to develop either open source or commerical applications.

Adminer

Adminer (formerly phpMinAdmin) is a full-featured MySQL management tool written in PHP. Conversely to phpMyAdmin, it consist of a single file ready to deploy to the target server.

LiquiBase

LiquiBase is a DBMS-independent library for tracking, managing and applying database changes. It is built on a simple premise: All database changes (structure and data) are stored in an XML-based descriptive manner and checked into source control. LiquiBase aims to provide a solution that: * ... [More] Supports merging of changes from multiple developers * Works well with code branches * Allows you to manage production data as well as various test datasets * Works in an environment where multiple machines will be attempting to migrate the database concurrently * Supports automated change-applying or generation of SQL scripts that can be approved and applied by a DBA * Supports rolling back changes * Database "diff" tool [Less]

Flourish — PHP Unframework

Flourish is a PHP unframework — a general-purpose, object-oriented library. It's architecture is modular and thus not strictly MVC. It focuses on being secure, broadly compatible, portable, well documented and easy to use. You will find Flourish useful if you need to write code that is any ... [More] of the following: - Secure - Consistent and easy to understand - Needs to effortlessly model simple or complex databases, especially existing schemas - Works with international data - Can perform accurate math calculations - Easily manipulates images - Able to run on different databases (MySQL, PostgreSQL, SQLite, MSSQL, Oracle, DB2) - Can be used on closed-source projects - Works with PHP 5.1+ - Might need an architecture other than MVC - Plays nicely with other libraries and frameworks [Less]

Cayenne

claimed by Apache Software Foundation

Apache Cayenne is an open source persistence framework licensed under the Apache License, providing object-relational mapping (ORM) and remoting services. With a wealth of unique and powerful features, Cayenne can address a wide range of persistence needs. Cayenne seamlessly binds one or more ... [More] database schemas directly to Java objects, managing atomic commit and rollbacks, SQL generation, joins, sequences, and more. With Cayenne's Remote Object Persistence, those Java objects can even be persisted out to clients via Web Services. Or, with native XML serialization, objects can be even further persisted to non-Java clients - such as an Ajax-capable browser. [Less]

SchemaSpy

SchemaSpy analyzes database metadata to reverse engineer dynamic Entity Relationship (ER) diagrams. It works with just about any JDBC-compliant database (Oracle/MySQL/DB2/SQL Server/PostgreSQL/Sybase/etc.) and can identify Ruby on Rails as well as other implied relationships.

SOCI

The database access library for C++ programmers that provides the illusion of embedding SQL in regular C++ code, staying entirely within the C++ standard.
