There are two ways of creating ORM models -
Model-First approach and Database-First approach. Entity Developer supports
both approaches for designing Entity Framework, NHibernate, LinqConnect, and LINQ
to SQL models.
Database-First approach allows you to use legacy database in your ORM application.
It supposes that you already have existing database and build your entity model
based on this database.
In Visual Studio Entity Data Models, entities are generated from the database tables
with help of Entity Data Model Wizard. In LINQ to SQL models, entities are generated
by dragging database tables from Server Explorer to the diagram. Entity Developer
implements both ways of generating entities from database tables - with Create Model
Wizard and by dragging database tables from Database Explorer to the diagram. They
are available for all supported types of models.
Entity Developer allows flexible tweaking for the generated names of the entity
sets, classes, methods and their members. You may configure case and pluralization,
removing and adding of prefixes and suffixes, etc. Naming rules can be set up on
the corresponding Create New Model wizard page or in the Model Settings dialog box.
Entity Developer offers many additional visual tools to configure mapping aspects,
that cannot be automatically generated from database. Creating inheritance hierarchies
is very easy and can be performed completely without manual editing of XML code.
For Entity Framework you may map entities to one or more tables or split table to
two separate entities, create entities (Defining Query) and procedures (Command
Text) from SQL statements, use complex types, and edit the storage part of the model.
When developing a model using the Database-First approach you may need to make changes
to your database and then reflect these changes in your model. With Entity Developer,
you can use Update From Database Wizard that allows synchronizing your model with
the database for both LinqConnect and Entity Framework in a fast and convenient
In Visual Studio, the Update Wizard performs such updating for Entity Framework
models. However, when updating model, the wizard resets all manual changes to the
model. Unlike standard Visual Studio Update Wizard, Entity Developer Update From
Database Wizard tries to preserve manual changes to the model where possible. The
wizard detects all the database changes that can affect the model, e.g. created
and deleted tables and views, their columns and foreign keys, column datatype changes,
created and deleted stored procedures and functions, changes to their parameters
"I tried Entity Developer and it works much better than the built-in model generator."
