At my company we have a database with one table being so big that it was splitted into 3 tables. They all share an ID and the info is NOT normalized so there is info for several entities in the tables, some entities actually have some fields in one table and some fields in the other tables.
There is a new project and they want to use nHibernate to map it, so that the code uses the ORM and we work on objects rather than query strings.
One of the problems we are having is that we are using nHibernates fluent “join” to map the 3 tables into one, but nHibernate won’t let you map components inside joins, also it seems liek you cant map components that are split several tables.
Is Entity Framework 4 capable of doing this?
Yes. So does EF 1. It’s called entity splitting.
