Database which is a collection or well organized and structured information is found in almost all the organizations whether it is school, college, Business Company, government or private offices, etc. Database is very important for carrying any kind of business or activities.
The telephone directory of your city; the railway time table or library catalogues are large collections of information. The telephone directory gives information about names, addresses and telephone numbers of people, the railway time table gives information about routes and timings of trains, while a library catalogue has information regarding all the books available in the library- title, author, publisher, edition, or which shelf it is available on. Each of the above collections of information is called database. A system that manages data, i.e. organizes, processes, and retrieves data, is called a database management system. In early days when there were no computers, handling of database were all done manually, which faced many problems.
Advantages of a Computer Database
The shortcomings of a manual database management system can be overcome to an extent by maintaining the database management so it helps to store, organize process and retrieve information much more efficiently. Some of its advantages are listed below:
- Large amounts of information can be stored easily on computers.
- All data is in one place. The same database can be accessed by people located different places.
- The database can be regularly updated from a single place. Hence there is no confusion about someone having the latest information and others not having it.
- The same database can be used to access information in different ways. A telephone database maintained on a computer will make it possible for us to find out someone's telephone number from the first name or the address, or to find the name and address of a person whose telephone number is known.
- Any number of different reports can be generated quickly from one database.
