51. What are Disconnected Recordsets? Advantages?
The ADO has the ability to work offline with recordsets.
The ADO Maintains the informations such as Database name,Server in which the database reside,username and password etc…After loacting a recordset it disconnects and work with them and finally send it back to the database by re-establishing the connection by making use of the already stored informations about the connetion and the database.
Advantage: Minimizes the Load on the SErver
