This was more of an intro to show that you don't need to do much coding to create a web service to access relational data.

I have just started using this technology mostly because I want to move toward web services. I played with web services in the past trying to serialize data for client side Javascript (JSON), which was difficult at best (it was easier to code it by hand). This seems useful in that you can create a diagram (edmx ADO.NET Entity Data Model) to represent your tables and relations, point this web service to it (svc ADO.NET Data Service), and bingo, instant serialized access to all the data.

Then, you can use Atlas (Microsoft Ajax) to do CRUD (create retrieve update and delete) operations within Javascript at the client browser without knowing a lot of what you are doing. Of course, if you get to this point, you probably know how to do these things anyway. This means you can create a Javascript variable, point it to the database "context" (or in this video, the "service:"), and have array access to records and object access to fields.

It's pretty cool stuff when you don't want all the details of coding, but isn't that the point of abstracting these technologies anyway?

1. Not sure, where in this DEMO you mentioned about Entity Framework, I have no-idea what you were trying to Demo

2. When you do a Demo like this, it would be great if you cna do a White Board with a small diagram about what you are going to Demo (Bth, this is something your team can suggest to all presenters). Picture speaks 1000 words :)

3. Saaid Kahn - I personally believe you could have slowed down a little with your Demo Speech, I could barely catch some of the words what you said (sorry, no offense we all are learning ;))

4. My 2 cents - Write down in a small piece of paper (or 3x4 Index cards) in what exactly you are going to Demo & go step-by-step, that will make things easy to understand.

I have watched all your videos on data, and this one seems the most "unfinished" IMHO. I still don't see EF as anywhere near finished, and being something one could decide to use on a million dollar project, especially if you know WCF.

This just seems to me an abstraction layer on top of WCF for people that don't or cannot learn WCF, that want all the "magic" to happen in the designer.

I will have a look again at EF in Visual Studio 10.
