NotORM is a PHP library, which greatly simplifies working with the data stored in the database. The library makes working with table relationships really easy. Attention is paid also on NotORM's overall performance and the library claims to actually run faster than a native driver. The simplified syntax of NotORM allows working databases in an intuitive and user-friendly way much alike SimpleXML for XML documents.
Unlike the other ORM solutions, NotORM does not need complicated setting up in order to work. NotORM is works directly with the already created database, which can itself be done with the existing GUI managers at hand.
The NotORM website provides great tutorials, presentations and examples of how to use the library. This greatly reduces the time the developers actually need to start working with the NotORM library.
