Building PHP Applications with Symfony, CakePHP, and Zend Framework Pdf Launch was inspired by as well as based on a Java ORM. implementation: Torque. Solutions utilized in both Propel and Torque are simple and effective, leading to great performance, but also possess some drawbacks. One drawback is actually one-to-one mapping (each course is mapped to 1 database table). With this strategy, it is necessary to create additional sign up for tables and write a few code to reflect many-to-many relations in the database.
Among the requirements for ORM within Propel is to create a good XML file that explains both database schema and also object model of application along with their connections. This document can also be generated by Push from an existing database. Using the XML schema, Propel may generate PHP model courses. Propel can also generate fine visual schema diagrams.Using Propel in source program code is really straightforward. All you need to perform is create an object along with then use its save() method, as in the following computer code. The object is now created into a database. For more complicated operations, Propel uses Requirements objects to formulate SQL statements
