Doctrine And ORM Designer
Edit: Shortly after positing this entry, Inventic contacted me with some responses. These are in italics.
I’ve been using Doctrine in conjunction with the Zend Framework for years. Although it is an excellent ORM, writing yaml by hand is a tedious and error-prone process. Furthermore, it can be difficult to visualize a large database from a series of text files, so I find myself maintaining a MySQL Workbench diagram in addition to the textual database representation.
