In the 1960s, Charles Bachman and IBM among others developed the first database systems. They developed into information management systems (IMS) that enabled the storage and retrieve large amounts information for a range of purposes, ranging from calculating inventory to supporting complex human resources and financial accounting functions.
A database is a set of tables that store data in accordance with the specific scheme, for example one-to many relationships. It uses primary key to identify records and allow cross-references between tables. Each table contains a number of fields, referred to as attributes, that represent facts about the entities that comprise the data. The most popular type of database currently is a relational model, created by E. F. “Ted” Codd at IBM in the 1970s. This design is based on normalizing data to make it easier to use. It also makes it easier to update data since it eliminates the necessity of changing many sections of the database.
Most DBMSs support multiple database types by providing different levels of external and internal organization. The internal level focuses on costs, scalability, and other operational issues like the layout of the database’s physical storage. The external level focuses on how the database appears in user interfaces and other applications. It can include a combination of various external views (based on the different data models) and could also include virtual tables that are constructed from generic data in order to improve performance.
