In the 1960s, Charles Bachman and IBM among others developed the first database systems. They developed into information management systems (IMS), which allowed large amounts data to be stored and retrieved for a variety of purposes. From calculating inventory to supporting complicated financial accounting functions, and human resource functions.
A database is a collection of tables that arrange data according to a certain scheme, like one-to-many relationships. It utilizes primary keys to identify records and allows cross-references between tables. Each table has a collection of attributes or fields which provide information about data entities. Relational models, invented by E. F. “TedCodd Codd in the 1970s at IBM as a database, are the most widely used type of database in the present. This design is based on normalizing data to make it easier to use. It is also easier to update data since it does not require changing certain sections of the database.
The majority of DBMSs support a variety of databases and offer different internal and external levels of organization. The internal level is concerned with costs, scalability, and other operational concerns like the layout of the physical storage. The external level is the way the database is displayed in user interfaces and other applications. It could comprise a mix of different external views based on different data models and can include virtual tables that are computed using generic data to improve the performance.
