What are the components of a DDBMS?
Components of Distributed Database System
The different components of DDBS are as follows:
Computer workstations or remote devices (sites or nodes) form the network system. The distributed database system must be independent of the computer system hardware.
Network hardware and software components that reside in each workstation or device. The network components allow all sites to interact and exchange data. Because the components-computers, operating systems, network hardware, and so on are likely to be supplied by different vendors, it is best to ensure that distributed database functions can be run on multiple platforms.
Communications media carry the data from one node to another. The DDBMS must be communications media-independent; that is, it must be able to support several types of communications media.
The transaction processor (TP), is the software component found in each computer or device that requests data. The transaction processor receives and processes the application's data requests (remote and local). The TP is also known as the application processor (AP) or the transaction manager (TM).
