In the 1960s, Charles Bachman and IBM along with other companies developed the first database systems. They evolved into information management systems (IMS), which allowed large amounts data to be stored and retrieved for a range of reasons. From calculating inventory to aiding complicated financial accounting functions, and human resource functions.
A database is tables that arrange data according to some scheme, such as one-to-many relationships. It uses primary keys to identify records and permit cross-references between tables. Each table has a variety of fields, referred to as attributes, that represent facts about the entities that comprise the data. Relational models, created by E. F. “TedCodd Codd in the 1970s at IBM, are the most widely used type of database currently. This design is based upon normalizing data to make it simpler to use. It is also simpler to update data since it does not require the changing of several databases.
Most DBMSs support different types of databases by offering different levels of internal and external organization. The internal level is focused on cost, scalability, as well as other operational issues like the physical layout of the database. The external level is the representation of the database in user interfaces and applications. It can include a mixture of different external views that are based on different data models. It may include virtual table that are computed using generic data to enhance the performance.
