LLBLGen is a framework that works well with most existing ORMs such as Entity Framework, NHibernate, Linq To SQL or even your custom ORMs, you can simply design the database modeling layer and then map it to your database. From now on you only need to write queries. LLBLGen maps objects easily in the relational model. It is widely used in many commercial projects around the world.
This product enables database modeling in either database-first or model-first approaches for developers, and switching between these two models is possible at each stage of the project. As it is more comprehensible to visual elements, this product, like other ORMs, uses graphical designers to map objects to the database, increasing flexibility, reducing errors, easier configuration and faster deployment. In the design of this product you can easily model thousands of different entities together.
