Object Relational Mapping design
$500-5000 USD
Paid on delivery
We want to integrate an Object Relational Mapping (ORM) layer into an existing application. We prefer to use LLBL Gen Pro as the ORM tool, but it's templates will need to be extensively modified.
Our business entities cannot inherit from base classes in the ORM layer. Basically, this project consists of modifying the templates that LLBL uses to generate the persistence code to remove the inheritance requirement. It will require writing some new templates. Writing LLBL templates isn't very difficult (if you think it is difficult, this is the wrong project for you). Where we need some real expertise is at the design/architecture level.
The LLBL runtime support classes will also need to be modified, but our own team is capable of doing this work -- it just needs to be coordinated with the design of this project, so it is the coder's responsibility too although we may be able to help with the implementation.
The persistence code must fully support our existing business objects and all their advanced functionality. We will not modify our business layer nor will we consider any solution that compromises our advanced business object functionality. All persistence optimizations and security features of the shipping LLBL templates must be maintained in the new/modified templates.
If you are an ORM expert (even if you haven't used LLBL Gen Pro before), please consider this project. (However, if you can't show us previous enterprise-level ORM projects, don't bother bidding.)

b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request.
3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).
