- Getting Started: Model First
- ============================
- .. note:: *Development Workflows*
- When you :doc:`Code First <getting-started>`, you
- start with developing Objects and then map them onto your database. When
- you :doc:`Model First <getting-started-models>`, you are modelling your application using tools (for
- example UML) and generate database schema and PHP code from this model.
- When you have a :doc:`Database First <getting-started-database>`, then you already have a database schema
- and generate the corresponding PHP code from it.
- .. note::
- This getting started guide is in development.
- There are applications when you start with a high-level description of the
- model using modelling tools such as UML. Modelling tools could also be Excel,
- XML or CSV files that describe the model in some structured way. If your
- application is using a modelling tool, then the development workflow is said to
- be a *Model First* approach to Doctrine2.
- In this workflow you always change the model description and then regenerate
- both PHP code and database schema from this model.
