LLBLGen Pro consists of two parts: the LLBLGen Pro designer and the LLBLGen Pro runtime framework (our own O/R mapping framework). You use the designer to create the entity/domain model, define the mappings and generate source-code for one of the four supported O/R mapping frameworks. You use the generated source-code combined with the O/R mapping framework of your choice to access your database and consume the data in that database.
