A Survey of Directory and Database Protocols for Data Extraction

Abstract

In today’s world for each and every one, the data is very important factor or data plays a very important role. The concept of computer data is coming from the eighteenth century, and in nineteenth, computer data is very important concept. In nineteenth most of the devices are having the data storage capability. So, this data storage capability leads the computer to invent various protocols. The protocol is the special set of rules that are used to access the data, to exchange the data and to communicate between various notes of computer. Mainly data is stored in databases or in directory servers in computer. The protocols are also used to compress the data, to notify the data sending device that data sending is over and to notify the receiving data device that data receiving is over. Depending upon the operation, protocols are classified into various types. Protocols are fallen under the Open Systems Interconnection (OSI) models. It consists of various layers and various protocols. Depending upon the use and application, protocols are used.
