PersistClass provides access to relational databases for PHP. It attempts to focus on simplicity and convenience by eliminating the need for boilerplate, meaningless code. It can establish database connections (MySQL, Oracle, etc.), execute SQL queries, parse query results, provide convenience methods (read a single row or value, etc.), escape data (against SQL injection, HTML escaping for outputs), handle transactions, and provide strict error handling and object persistence (storing and retrieving PHP objects in db tables).
Ujorm is an easy-to-use ORM framework based on key-value objects. The framework was designed for rapid Java development with great performance and a small footprint. The key features are type safe queries, relation mapping by Java code, no entity states, and a memory overloading protection cache.
DBIx-Class is an SQL to OO mapper with an object API inspired by Class::DBI (with a compatibility layer as a springboard for porting) and a resultset API that allows abstract encapsulation of database operations. It aims to make representing queries in your code as Perl-ish as possible while still providing access to as many of the capabilities of the database as possible, including retrieving related records from multiple tables in a single query.
pdoMap is a robust PHP ORM with many OOP features. The mapping structure, requests, and transactions are defined in XML files. The core directly generates PHP classes for high performance. It is very easy to use and configure. It features fully optimized code, caching data, a full lazy loading system, and an open system for extending all functionality.
KeyAccess is a light-weight object-relational mapping (ORM) tool for Java, using existing databases as the starting point to generate a domain model. Its main goal is to reduce and sometimes eliminate manual updating between your domain object model and the underlying databases, while still being able to use arbitrarily complex SQL queries. In addition, KeyAccess doesn’t mandate a special architecture or framework – it will work in any application using JDBC.
RedBeanPHP is a zero-config, easy-to-use object database for PHP and an ORM tool. It works very simply. Just create bean objects and throw them at RedBean. RedBean will analyze your objects and infer a readable, comfortable data scheme from it and create all required tables and columns on the fly. RedBean is not schemaless, it makes neat tables and columns for you, but on the fly without any configuration.
