Publisher review:Propel is an Object-Relational Mapping (ORM) framework for PHP5. Propel is an Object-Relational Mapping (ORM) framework for PHP5.
It allows you to access your database using a set of objects, providing a simple API for storing and retrieving data. Propel allows you, the web application developer, to work with databases in the same way you work with other classes and objects in PHP.
Features:
- You don't have to worry about database connections or writing SQL -- unless you want to.
- You never have to worry about escaping data or type-casting results.
- You define your database in a simple XML format (or tell Propel to build it from an existing database) and Propel will create database initialization files for your database and will generate static classes and objects that provide an OO interface to your database. (It can generate other useful things based on the datamodel too!)
- Propel builds classes which are aware of the structure of your database so there's no performance lost to initialization or to on-the-fly database metadata queries.
- makes it possible to easily integrate with other components driven by your data model (e.g. a form generation tool could also use the same XML schema) or to extend the schema definition to include attributes for other components (e.g. more validation informat for that form tool).
Easily customizable. The generated object model is built to be customized. All internal calls are made to empty stub classes which extend the classes with generated logic. You can override behavior in the stub classes or provide your own custom business logic without sacrificing the ability to rebuild your object model at a later time.
Plays nice. This is a way of saying that Propel doesn't force you to use only Propel tools. For example, while you can use the Criteria objects to construct queries without writing SQL, we recognize that Criteria doesn't do everything and so we've also made it easy to use custom SQL to populate generated objects.
Truly independent. The use of a build process to create customized SQL and PHP classes means that your database interactions with Propel are truly database-independent -- taking advantage of the strengths of your RDBMS and providing emulation for things your RDBMS doesn't support (e.g. fkey cascading deletes in MySQL). Tools are also provided to easily move data from one RDBMS to another.
Intuitive, Predictable. Propel's data model definition is follows very closely the structure of the underlying database. This provides the advantage of making Propel easy to understand and also of behaving predictably with very complex data models.
Advanced. Propel makes the difficult relational problems easy and efficient. For example, Propel provides the ability to populate related (foreign key) objects from a single query. Propel also supports basic (table per class tree) inheritance and other advanced OO features.
