With Entity Developer you don't need to limit yourself in choosing a design approach – Model-First, Database-First or mixed – Entity Developer supports any of them. With Update to Database and Update from Database wizards you can easily synchronize your model and database in any direction. For example, you may generate model from the database, then edit it, and apply these changes to the database with Update to Database Wizard. When updating a database, Entity Developer makes only necessary changes to the existing model database and retains the data if possible. The database does not need to be re-created.
