 A while back I posted a blog entry about Microsoft's feature addition to Visual Studio - Entities (or ADO Entity Data Model). In that post, I complained that the "redefining" of the term Entity Data Model was going to lead to even more confusion on development projects.
Today I watched an online video of using Visual Studio to work with Entity Data Model functions . While it didn't help assuage my misgivings about calling this feature Entity Data Modeling, it did help me understand what Microsoft means by data modeling. For now, it appears to be database modeling via reverse engineering of databases.
One of the things I did note, though, was that I preferred some of the graphical presentation features of the actual entities. The gradient shading and the drop shadows gave the models more visual appeal than most tools I work with. I know that these sorts of features come with a performance price, but I still think they were more visually pleasing.
I'm thinking of giving Visual Studio a try to see how these graphical features come out in printing and other presentations.
What do you think of them?

Re: ADO Entity Data Model Video
I like those graphical features, but I'm not sure about some of the other features of the tool. The model was created from a database, but the relationship between Order and Product didn't appear to be supported by a FK column. I'm sure it must be there, but why hide it? The presenter also seemed to be filling in the gaps in the captured stored procedures (I've never written one, so perhaps my observation doesn't mean much :) ).
I wish Microsoft would desist from calling things 'Entities' when they are neither entities nor entity types; they're obviously tables (though I was confused when the presenter talked about 'mapping' database things to model things).
