Propel is an open-source Object-Relational Mapping (ORM) for PHP5. It allows you to access your database using a set of objects, providing a simple API for storing and retrieving data. Propel uses PDO as an abstraction layer, and code generation to remove the burden of runtime introspection. Therefore Propel is fast. Propel implements all the key concepts of mature ORM layers: the ActiveRecord pattern, validators, behaviors, table inheritance, reverse engineering an existing database, nested sets, nested transactions, lazy loading, LOB, etc. Propel supports MySQL, PostgreSQL, SQLite, MSSQL, and Oracle.

The Qcodo Development Framework is an open-source PHP web application framework which builds an Object Relational Model (ORM), CRUD (Create, Retrieve, Update, Delete) UI pages, and AJAX hooks from an existing data model. It additionally includes a tightly-integrated HTML and JavaScript form toolkit which interfaces directly with the generated entities. It is a robust, comprehensive framework which can be utilized by small and large Web applications alike. The framework consists of three main components: the Code Generator, QForms (OOP generated stateful Ajax- or server-processed webform), QQuery (OOP based SQL Query builder) -- all of which can be used independently of each other. The Code Generator parses an existing Relational Database structure, and builds an ORM, as well as several remote interfaces (SOAP, AJAX) to the ORM. The ORM in Qcodo can be extended to provide user-maintained functionality (via object subclassing). QForms is a ASP.NET-inspired templating engine in which each form element is an object exposing its functionality and state via methods and attributes.

The main strength of Vici CoolStorage is the ease of use. Most ORM tools still require a lot of unneeded code to accomplish basic data persistence tasks, but Vici CoolStorage is designed to relieve the programmer from these tedious and error-prone tasks, making it very intuitive to use.
<ul>
	<li>Supports SQL Server 2000/2005, MySQL, SQLite, MS Access and VistaDB. Other custom providers can be added.</li>
	<li>Full support for MonoTouch (using SQLite)</li>
	<li>Session-less and context-free database access</li>
	<li>Any existing relational data model can be mapped to CoolStorage objects with minimal effort</li>
	<li>No code generator required. Mapping is done by creating simple classes.</li>
	<li>All relation types are supported: One-To-Many, Many-To-One and Many-To-Many</li>
	<li>Completely typed object model (no type casts required)</li>
	<li>Dirty tracking on the column level. Only changed fields are persisted to the database</li>
	<li>Full support for transactions, including ##TransactionScope##</li>
	<li>Nullable columns can be mapped to nullable fields or to a default value</li>
	<li>Delayed (lazy) loading of data to minimize database access. Configurable per field.</li>
	<li>Selective or automatic prefetching of all relation types for improved query performance</li>
	<li>Powerful and intuitive database-independent object query language</li>
	<li>Flexible event mechanism to intercept any event</li>
	<li>Identity (auto-increment) keys or sequences are supported for all database types</li>
	<li>Support for server and client generated Guid keys</li>
	<li>Objects can be mapped to different databases, even across object relations</li>
	<li>Paging of object collections (at server level)</li>
	<li>Extensive support for retrieving aggregate values on collections (count, sum, average, ...)</li>
	<li>Collections implement IBindingList so they can be used by controls (grids) as a data source</li>
	<li>Underlying database engine uses optimized and parameterized SQL queries. SQL injection is impossible</li>
	<li>Built specifically for .NET 2.0 and up, taking full advantage of generics and nullable types</li>
	<li>Raw SQL and/or stored procedures can be called on the underlying database without the need for a separate database connection</li>
	<li>Small footprint (less than 250 KB, including Vici Core)</li>
</ul>
