Once received, the SQL statement is processed by the server, and the results are returned to the client application. Network traffic is kept to a minimum because only the requests and the results are shipped over the network. Net8 is the Oracle network interface that allows Oracle tools running on network workstations and servers to access, modify, share, and store data on other servers. Net8 is considered part of the program interface in network communications. A communication protocol is a set of standards, implemented in software, that govern the transmission of data across a network.
Communication protocols define the way that data is transmitted and received on a network.
In a networked environment, an Oracle server communicates with client workstations and other Oracle servers using Net8. Net8 supports communications on all major network protocols, ranging from those supported by PC LANs to those used by the largest mainframe computer systems. Without the use of Net8, an application developer must manually code all communications in an application that operates in a networked distributed processing environment. If the network hardware, topology, or protocol changes, the application has to be modified accordingly. However, by using Net8, the application developer does not have to be concerned with supporting network communications in a database application.
