Maping of Component collections

Post by gr8user » Tue 04 Oct 2016 00:19

Hi,
Could you please check the result for Oracle DB script for "Component Collections Support":
====
Classic mapping of component collections is pretty much alike mapping of a one-to-many association between two entities of a model. The major difference is that the model does not have an entity corresponding to a details table, and instead of it the model contains a complex type consisting of a set of properties similar to a part of the details table field set. Whereas an association is built between an entity corresponding to a master table, and a complex type corresponding to a part of the details table field set. The master entity contains a navigation property which is a reference to a collection of complex type details.

When I did all steps I got script contained only Dept table and nothing about Emp table. Is that right?

That is correct, because you remove the Emp table from the model when walking through tutorial, and the model stores only some properties of Emp.
