Network DataBase protocol
NDB defines a protocol for use with relational database systems in a TCP/IP environment. It has the following objectives:
- To allow any workstation/mainframe users and applications to issue SQL statements interactively or imbedded within the application programs, to access any database on any operating system.
- To distribute the applications of a database host to a requester machine.
NDB is built on the Remote Procedure Call (any arbitrary implementation of RPC) using the client/server model. Please see Figure - Components in the Network Database (NDB) Protocol for an overview of the various NDB components.
