We are in the process of developing a project whose goal is to replicate an ASP classic application to ASP.Net 4.0. The system must be fully web. There are several new requirements for the new system that make this complex project:
The system must be database independent. It should support MS SQL Server, Oracle, MySQL, Postgres, and DB2 in version 1.0.
The system should be able to provide easy reporting from the database with third-party reporting packages.
The system should allow the administrative end user to create their own tables in the database through a web interface.
The system should allow the administrative end user to create / configure a user interface (based on the Internet), where they can select tables and fields in the system (either our system main tables, or their own user tables created in # 3)
The system should allow the administrative end user to create and maintain relationships between these custom tables, as well as between these tables and the tables of the main systems.
The system should allow the administrative end-user to create business rules that will check, show / hide user interface elements, block certain actions based on the identification of specific users, certain user groups or privileges.
