In the 1960s, Charles Bachman and IBM among others came up with the first database systems. They evolved into information management systems (IMS) which allowed huge amounts of data to be stored and retrieved for a range of purposes. From calculating inventory, to supporting complicated financial accounting functions, and human resource functions.
A database is tables that arrange data in accordance with a specific pattern, for example, one-to-many relationships. It uses the primary key to identify records and permits cross-references among tables. Each table is comprised of a set of attributes, or fields, which provide information about data entities. The most popular kind of database is a relational model developed by E. F. “Ted” Codd at IBM in the 1970s. The design is based on normalizing the data, making it more easy to use. It is also simpler to update data because it does not require the changing of certain sections of the database.
Most DBMSs support multiple database types by providing different levels of rakastunners.com internal and external organization. The internal level is concerned with cost, scalability, and other operational issues, such as the physical layout of the database. The external level is the representation of the database in user interfaces and applications. It could include a mix of external views based on different models of data and may include virtual table that are calculated using generic data to improve the performance.
