Data is raw and unorganized facts that are useless without proper processing and organising them to retrieve some information for future use . Data is a set of facts and statistics that can be operated, referred or analyzed. It can simply be a piece of information, a list of grocery items, or observations, a story or a description of a certain scenario. 2. METADATA : Metadata is a data about data. Metadata shows basic information about data, which can make finding and working with specific instances of data easier. Metadata increases the accuracy of searching and operating of data from large amount of data. It helps in fetching piece of some data that is required from the bundle of data vastly, Metadata provides the information regarding organization of raw data. It may be created manually or by automatic information processing. Manual processed metadata is more accurate than automatic information processed one because automatic information processed metadata only contains file name, size, extension, time of creation and information about who created the file.
