Database Switching includes execution of queries on same or different machines connected in LAN with different backend without rewriting any queries.Switching between the databases reduces the work of rewriting the queries for each of the database thus saving time.User just has to select the Source DBMS and Table from that DBMS and a switch file is created on a click of a button.Now this switch file can be used in any machine (can be a remote machine) to switch data in any of the DBMS.Database GUI helps a user to do all database operations through a GUI provided with minimal knowledge of the database.Here user can do all database activities like Creating Table, Inserting Data, Joining two tables etc with minimal knowledge of queries without having the knowledge of whole database can access through GUI.
