There is a tool that you can download free trial for.

it Captures metadata within a repository from Relational, SSRS, SSAS and SSIS and ties it all together to allow you

to perform impact analysis and search via a web portal.

You can also maintain and extend this metadata centrally via a collaboration feature in the portal.

There are also video demos on the website.

here's the link.
