Database : A database is a collection of information that is organized in a specific order so that it can be accessed easily, managed and updated. It supports storage and manipulation of data. Data stored in a database are organized into rows, columns and tables. Each data is indexed which makes it easier to find the relevant information. Rows are also called as records are a group of fields within a table which are related to a specific entity. New information can be added, deleted or updated in the database. Database administrator: For multiuser database or inter-organizational database, the procedure becomes more important and difficult. For the large internet and intranet databases, the responsible for database administration is too time consuming and it’s difficult to handle even by the full-time person. So to handle these large applications, the person who has both technical and diplomatic skill is usually required to handle this situation, which can be tackled by an office of the database administration. The manager of the office is known as database administrator.
