In the 1960s, Charles Bachman and IBM along with other companies developed the first database systems. They developed into information management systems (IMS) which enabled the storage and retrieve massive amounts of information for a range of uses, from calculating inventory to supporting complicated human resources and financial accounting functions.
A database is a set of tables that arrange data according to a certain scheme, like one-to-many relationships. It uses the primary key to identify records and allows cross-references between tables. Each table is comprised of a variety of fields, called attributes, that provide information about the data entities. Relational models, invented by E. F. “TedCodd Codd in the 1970s at IBM and IBM, are among the most popular database type currently. This design is based on normalizing data to make it more user-friendly. It is also easier to update data because it doesn’t require changing various databases.
The majority of DBMSs are able to support multiple types of databases through different levels of external and internal organization. The internal level is concerned with cost, scalability, and other operational issues like the physical layout of the database. The external level is the representation of the minnmedstaging.wpengine.com database on user interfaces and applications. It could comprise a combination of different external views (based on different data models) and could also include virtual tables that are computed from data that is generic to enhance performance.
