pThe first database systems were invented 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 large amounts of data for a variety of applications, from the calculation of inventory to supporting complex human resources and financial accounting functions.

pA database is a set of tables that are organized according to a particular schema, such as one-to many relationships. It uses the primary key to identify records and allow cross-references among tables. Each table has a collection of fields, referred to as attributes, that contain information about data entities. Relational models, which were developed by E. F. “TedCodd Codd in the 1970s at IBM and IBM, are the most popular database type in the present. This model is based on normalizing data to make it simpler to use. It also makes it simpler to update data without the need to update different sections of the database.

pMost DBMSs support multiple database types by providing different levels of external and internal organization. The internal level is concerned with costs, scalability, and other operational issues including the layout of the databases physical storage. The external level is the way the database is represented in user interfaces and other applications. It could include a mix of different external views (based on different data models) and can also include virtual tables that are constructed from data that is generic to enhance performance.
