Where to find a database plugin?

Hi,
I need to create different database (MySQL) where I can put a lot of fields for example memberinfo where the user can edit THEIR OWN record but have the ability to search/see ALL members and sort them. Admin should be able to edit all user and export to Excel or as csv. Put up different pages with extract from the databases and so on.

Where can I find like that? Have only so far found one that is nearly like that from wordpress.org (Custom Tables) the Premium Version. But there must someone in the world that have som similar need? One MySQL that was nearly perfect (But expensive) is SQL Maestro but then I have problem with secure the page/database and also to not need to login extra time for connection to the right user from logged in to wordpress.

Someone with ideas?

Take care / Lars
