Data Access Middleware & a Business User's view of data

Hello,

I need to increase my knowledge about "data access middleware" and my questions will probably reinforce that fact!

Can anyone recommend a solution that can be used to provide multiple software applications & users access to multiple data sources via a single common logical piece of software (i.e. data access middleware)?

With capabilities that may include:

• Presenting a common simplified view of our databases and data sources via a business user oriented metadata layer. Primarily for persons using reporting tools but possibly also our software developers.
• Connecting to and joining together multiple different databases via the one interface.
• Insulating applications from changes to those data sources.
• Providing an additional level of security within the middleware.

What might you expect to pay?

Thanks,
