Hello, I am brainstorming something for a project I am working on:

Suppose I have created an API for a website that I would now like to use in a new module for DNN.  In the current model, there is a section to include the database execution.  Because I have this API that already connects to its own database, I feel that I do not need this layer.  I would however like to use the power of DNN to create my modules. 

My question to any developers down this path, what do you think the best practice is for this problem?  I could simply bypass the database layer, but I feel that it would be considered bad practice and I may be missing in some of the features that DNN has to offer.

I am willing to create a database adapter for my API to plug into the DNN model, but I do not want to recreate the API, because it defeats the purpose of rewriting the code.  Anyone else have any issues with something like this?  Any help or just ideas would be greatly appreciated.

Thanks,
M Doyle

Seems to me - it really comes down to what you want to do with the modules you are building.

What the DAL really does in DNN is provide a mechanism to abstract access to the database and provide object hydration tools.

If you have your own data access API then for your own purposes - you may as well continue to use it for accessing your own data structures.

I guess the only reason you would not - was if you were planning on delivering the module as a commercial product and you wanted to allow for future connect to DAL supported data providers in the future

If you use the DAL+ it will require less code than if you used your own DAL

One if the really cool things about the DAL+ concept is that you are only working with one file for all your data access routines ...

Under the DAL system you are fighting with multiple classes spread across multiple files - which greatly increase the debug - typo cycle.

In large multi module projects - these days I often put all the userinfo definitions in one .vb container and the controller code in a second .vb container - the result is a one stop shop for all data access needs.
