The Data Encryption Standard DES is a cipher (a method for encrypting information) selected as an official Federal Information Processing Standard (FIPS) for the Data warehouseA data warehouse comprises a computing system used to store information regarding an organization's activities in a database. The database design favours reporting on and analysing the data in order to gain strategic information and to facilitate decision Data compressionIn computer science, data compression is the process of encoding information using fewer bits, or information units, thanks to specific encoding schemes. For example, this article could be encoded with fewer bits if we accept the convention that the word DatabaseA database is an information set with a regular structure. Any set of information may be called a database. Nevertheless, the term was invented to refer to computerised data, and is used almost exclusively in computing. Sometimes it is used to refer to no Data setIn statistics, a data set is a set of data consisting of: #a list of research subjects and #the data vector associated with each.
