Web-based programming environment for replacing an old Delphi-based system

The client system based on Delphi 5, thousands of lines of code, begins to collapse. Problems with new drivers and operating systems are major problems.

We assume a complete rewrite, the module at a time, and want to look at the browser-based interface. The database is Oracle 10, which we could replace if that makes sense.

Primary requirements:

  • Acquired by a company or user community that is stable enough to be in the next 5-7 years (we are realistic on this).

  • The ability to quickly interact using stored procedures from Oracle and web services created in ASP.NET and ColdFusion as data sources.

  • Deployed on virtualized clients, as well as on thick Windows and Apple client computers.

  • Extra points, if there is a way to reuse the old Delphi code (but again, we are realistic, so we do not expect this to happen).

We see Silverlight, Flex, and Ruby as possible development environments. Does anyone have any other recommendations or comments on the above?

Thank you for your help.

There are many factors associated with a choice. First of all, I would ask, what do you know? If the answer is only to “preserve an outdated system”, then you, in fact, start from scratch in terms of knowledge about new technologies.
