The application itself logs into the DBMS, and handles any user account issues internally. The number of users actually performing a request at any given time is usually a very small percentage of the total number of active users, and during request processing is the only time that a database connection is required. Opening a connection per user can be unfeasible in a publicly-hosted Internet application where the number of simultaneous users can be very large.Īccordingly, developers often wish to share a “pool” of open connections between all of the application’s current users. In Java Development Creating a new connection for each user can be time consuming (often requiring multiple seconds of clock time), in order to perform a database transaction that might take milliseconds.
