The first database systems were invented in the 1960s by Charles Bachman, IBM and others volkschoice.com. They evolved into information management systems (IMS) which enabled the storage and retrieve large amounts of data for a variety of purposes, ranging from calculating inventory to supporting complicated financial accounting and human resources functions.
A database is a set of tables which organize data according to an established pattern, such as one-to many relationships. It uses primary keys to identify records, and allow cross-references between tables. Each table contains a number of fields, also known as attributes, that contain information about the data entities. The most popular type of database that is currently in use is a relational model, developed 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 doesn’t require changing certain sections of the database.
The majority of DBMSs support a variety of databases, offering internal and external levels of organization. The internal level is concerned with costs, scalability, and other operational issues such as the layout of the physical storage. The external level is the representation of the database in user interfaces and applications. It may include a mix of various external views based on different data models. It also may include virtual table that are calculated using generic data in order to improve the performance.
