  Re: what is meant by connection pooling and event pumbling in ado.net
Answer
# 1
Connection Pooling:-
Connection pooling reduces the number of times that new
connections need to be opened. The pooler maintains
ownership of the physical connection. It manages
connections by keeping alive a set of active connections
for each given connection configuration. Whenever a user
calls Open on a connection, the pooler looks to see if
there is an available connection in the pool. If a pooled
connection is available, it returns it to the caller
instead of opening a new connection. When the application
calls Close on the connection, the pooler returns it to the
pooled set of active connections instead of actually
closing it. Once the connection is returned to the pool, it
is ready to be reused on the next Open call.

connection pool is set of active connections object,so that
someone else can make use of it without waiting of creating
the new connection.The number of connections allowed to a
particular database may be limited due to server capacity
or database licensing restrictions.

when a connection opened first time the connection pooling
is created , and is based on the exact match connection
string given to the connection object.
It works only the connection string is same.otherwise it
will open a new connection. Hence connection pooling
maintains all these coneections to made the retreive of
data effectively and fastly.
