Introduction:
A client is any application that connects to Oracle Database to send or retrieve data.
Oracle Net establishes and maintains the connection between the client application and the database over a network, and exchanges messages between them using industry standard protocols.
For a client application and a database to communicate, the client application must be able to identify the database it wants to connect to, and the database must provide an identification.

You can use a service name to connect to a database. A service name is a logical representation of a database, which is the way a database is presented to clients. A single database can be presented as multiple services.
Service names can provide location transparency so that the client application does not have to know the server’s location. If the database is moved to another location, then you must reconfigure only Oracle Net. No changes are necessary to client applications.
