The first database systems were created in the 1960s by Charles Bachman, IBM and others. They evolved into the information management systems (IMS) which made it possible to store and retrieve massive amounts of data for a wide range of applications, from the calculation of inventory to supporting complex human resources and financial accounting functions.
A database is a collection of tables that store data according to an established pattern, such as one-to-many relationships. It uses primary keys to identify records and allows cross-references between tables. Each table is comprised of a set of fields called attributes that contain information about data entities. The most popular type of database that is currently in use is a relational model designed by E. F. “Ted” Codd at IBM in the 1970s. This model is based upon normalizing the data, making it simpler to use. It is also simpler to update data since it does not require the changing of several databases.
The majority of DBMSs are able to support different types of databases by offering different levels of external and internal organization. The internal level is concerned with cost, scalability and other operational issues, such as the layout of the physical storage. The external level is the representation of the database on user interfaces and applications. It can include a mixture of various external views based on different data models and could include virtual tables that are calculated using generic data in order to improve the performance.
