[dba-VB] Dynamic Data Entities Web Applications

Hi Shamil and Charlotte

I watched that video - some challenge due to the awful soundtrack - and my impression is that this dynamic data entities web is useful only for creating an interface to the complete table schema - which you hardly never use (I haven't) except for the example Shamil describes where you wish to present the full schema as well as the data content and even offer to edit this at close to zero efforts. I could imagine some kind of monitoring or admin/techie interface built this way.

For any other purpose a lot of customizing is needed which - though quite powerful, so it seems - for a decent app will take longer than building the app from scratch I guess. 

So - as I see it - this technique has its uses but app development is not on of these.

Hi Charlotte --

Thank you for your information.

As I noted I currently do not plan to use dynamic data entities web
applications in production but only to verify the data model design, to give
to customers/users "working model" of some of their business areas, to
prepare lookup/sample/test data: I found it very useful -  I have just
developed rather complicated data model for my customer project, clicked
several times my mouse, made a few selections, typed a few chars - and
voila' I can enter data, navigate all tables etc.

Would that be possible to get known from your project manager what are the
causes of their warnings about dynamic data entities? - I think that would
be very useful for everybody here to know about their experience to not
"step on rakes" as we say here.

BTW, customization features provided by dynamic data entities web
applications are also rather useful to implement something like "working,
real life environment simulating specification": I have got only glanced
those customization features and I have found they can be used at least to:

- develop/simulate/test some kinds of (simple) business rules/checks used during data entry/edit;
- develop almost ready to use in ASP.NET production environment ASP.NET custom controls.

There should be more useful features I'm quite sure.

And once again what is very important is that you can give "working model"
for your customers/users almost immediately after/during the talks with
them, they can play with it, they can get "instant fixes" for it etc. I have
checked and AFAIS ADO.NET Entity Data Model can be quickly regenerated
within VS2008 when source DB changes, and such regeneration preserves custom
edits of ADO.NET Entity Data Model objects. Good stuff. Only positive
experience so far.

Thank you.

Our project manager warned us about dynamic data entities and the MS entity model.  No personal experience and he isn't a developer, so he's talking about his previous job.

Hi Gustav,

VS2008 SP1: 

1. Solution: Add: New Project -> Dynamic Data Entities Web Application...
2. Project: Add: New Item -> ADO.NET Entity Data Model

The next steps are rather obvious, and Global.asax's comments give the clue how to make the application to work.

But I can't get some more information on this type of projects. Yes, I can investigate them but I'd prefer to have some ready to use descriptions. 

Can't find them online on MSDN....

I have just got this link, which looks interesting:

It's a 1+ hour video...

Thank you.

Hi Shamil

Hi All,

I'm currently working on a project where I use Dynamic Data Entities Web Applications - DDEWA-(VS2008 SP1).

I have tried to search Google and Bing to find some information on DDEWA but failed.

Do you have any useful links on DDEWA?

Thank you.
