http://romiller.com/2010/09/29/ef-ctp4-tips-tricks-code-first-inheritance-mapping/ is an article about how codefirst handles inheritance during table generation. To sum up, default table generation strategy is
Table-per-Hierarchy (TPH)which keeps all data in one table created for the base type and automatically creates a
Discriminatorfield in order ro discriminate different types.
Table-per-Type (TPT)creates a table for the base type with shared columns and different tables for each derived type whereas
Table-per-Concrete Class(TPC)creates an entirely different table for each class.. However, when the table generation strategy is modified, previously working code may start to blow up.. Moreover, performance is best when the default strategy (TPH) is used: http://blogs.msdn.com/b/adonet/archive/2010/08/17/performance-considerations-when-using-tpt-table-per-type-inheritance-in-the-entity-framework.aspx
