The information stored in the catalog is called the Brother Cell Phone List metadata, it describes the primary database. Hence this approach will work on any type of database for example, insurance database, Airlines, banking database, Finance details, and Enterprise information database. But in traditional file processing system the application is Brother Cell Phone List developed for a specific purpose and they will access specific database only. The other main characteristic of the database is that it will allow multiple users to access the database at the Brother Cell Phone List same time and sharing of data is possible.
The database must include concurrency control software to Brother Cell Phone List ensure that several users trying to update the same data at the same time, it should maintain in a controlled manner. In file system approach many programmers will be creating files Brother Cell Phone List over a long period and various files have different format, in various application languages. Therefore there is possibility of information getting duplicated, this redundancy is storing Brother Cell Phone List same data multiple times leads to higher costs and wastage of space.
This may result in data inconsistency in the Brother Cell Phone List application, this is because update is done to some of the files only and not all the files. Moreover in database approach multiple views can be created. View is a tailored representation of Brother Cell Phone List information contained in one or more tables. View is also called as "Virtual table" because view does not contain physically stored records and will not occupy any space. A multi-user database Brother Cell Phone List whose users have variety of applications must provide facilities for defining multiple views.
