The differences between Typed and untyped databases

As mentioned else where I am new to database programming.. and although I feel I am progressing rapidly I still can't figure out the difference between typed and untyped databases...  !!

At one point I came to think that typed databases are the ones you build by letting VB create the objects connecting your interface to the database (SQL connection, SQL data adapter and dataset) while untyped databases are the ones where you create the said objects through code..

Obviously I was wrong... so.... would some one offer the clearest explanation of the difference between the two....

    It appears that I can't  get the sample application to run connect to Northwind database on SQL server 2005 express which is the only SQL server I have... I tried running the script that comes with the file and also tried attaching the database, but the sample application failes to see the connection and keeps instructing me to have the database installed on SQL Server...

    I will settle for an explanation from you or a different sample to clarify the difference
