Database Management Basics

Database management is the method for managing information that aids the company’s business operations. It involves storing data, distributing it to application programs and users and modifying it as needed and monitoring the changes in the data and preventing the data from becoming damaged by unexpected failure. It is an integral part of the entire informational infrastructure of a business that supports decision making and corporate growth as well as compliance with laws such as the GDPR and the California Consumer Privacy Act.

In the 1960s, Charles Bachman and IBM among others developed the first database systems. They evolved into information management systems (IMS) that made it possible to store and retrieve large amounts data for a variety of applications, from the calculation of inventory to supporting complex human resources and financial accounting functions.

A database is a collection of tables which organize data according to the specific scheme, 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 which provide information about data entities. Relational models, which were developed by E. F. “Ted” Codd in the 1970s at IBM and IBM, are among the most popular database type today. This model is based upon normalizing the data, making it more easy to use. It is also easier to update data because it doesn’t require changing various databases.

The majority of DBMSs are able to support multiple database types by providing 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 focuses on how the database is represented in user interfaces and other applications. It can include a combination of various external views (based on the various data models) and may include virtual tables that are computed from generic data to improve performance.
