Guys, I have an assignment question here... I'm not asking for code or anything, but rather some light shed on this very vague requirement...

We have been asked to setup a retrieval system, using ASP.NET or PHP to retrieve contents from "multiple" databases. The content should be of all different formats.

Any idea's/

In your queries, just put the database name in front of the table name. For example:

$query=mysql_query("SELECT * FROM DATABASE1.TABLE1");

What do you mean by that?

I need to access mutiple database, not multiple tables.

And multi-format including a text db, an image db and possibly an audio db. Eac DB storing and handling different media formats... You know.

4 part naming
server.database.schema.object

Or separate connection objects using different connection strings (see www.connectionstrings.com)
