Database management is the method for managing data that supports an organization’s business operations. It involves storing data, distributing it to users and applications, editing it as needed and monitoring changes to the data and preventing data corruption due to unexpected failure. It is a component of the overall informational infrastructure of a company that aids in decision-making, corporate growth, and newsite.inprodi.com.mx compliance with laws like the GDPR and the California Consumer Privacy Act.
In the 1960s, Charles Bachman and IBM among others developed the first database systems. They developed into information management systems (IMS) that enabled the storage and retrieve massive amounts of data for a broad range of uses, from calculating inventory to supporting complex financial accounting and human resources functions.
A database is a set of tables that organize data according to a particular pattern, for example, one-to-many relationships. It utilizes primary keys to identify records and permit cross-references between tables. Each table contains a set of attributes or fields that contain information about data entities. The most well-known type of database today is a relational model, developed by E. F. „Ted” Codd at IBM in the 1970s. This model is based on normalizing the data, making it simpler to use. It also makes it simpler to update data, avoiding the need to modify many sections of the database.
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, as well as other operational issues, including the physical layout of the database. The external level is the way the database appears in user interfaces and other applications. It could include a mix of various external views (based on the various data models) and may also include virtual tables which are generated from generic data in order to improve performance.
