Application Servers (278)

An application server provides access to the data for the client. It serves as an
interface between the client and one or more database servers, which provides an
additional level of security. It can also perform some of the query processing for the
client, thus removing some of the load from the database server.

The application server assumes the identity of the client when it is performing
operations on the database server for that client. The application server’s privileges
are restricted to prevent it from performing unneeded and unwanted operations during a
client operation.
