I (am a data warehouse architect with no web programming experience ) volunteer for an organization (with no budget) and need to create a website that will allow users to specify filter criteria, execute a query on a database based on the filter criteria, and allow the user to export the result into a spreadsheet. Since the data is sensitive, the security must be as good as possible.
I have been researching free Microsoft products, etc. It does not need to be pretty. I want to select the software to be used so that I know its capabilities before starting the design. I would appreciate any ideas.
