Database Management Basics

Database management is the process for managing information that aids the company’s business operations. It involves storing data, disseminating it to applications and users making edits as needed and monitoring changes to data and making sure that data integrity is not compromised due to unexpected failure. It is an element of an organization’s overall informational infrastructure that aids in decision-making and corporate growth, as well as compliance with laws such as the GDPR and the California Consumer Privacy Act.

The first database systems were invented in the 1960s by Charles Bachman, IBM and others. They developed into information management systems (IMS), which allowed large amounts data to be stored and retrieved for a variety of purposes. From calculating inventory to aiding complex financial accounting functions and human resource functions.

A database consists of a set of tables that organize data according to a certain pattern, for example, one-to-many relationships. It uses the primary key to identify records and permits cross-references between tables. Each table has a collection of attributes, or fields, that represent facts about data entities. The most popular type of database that is currently in use is a relational model designed by E. F. “Ted” Codd at IBM in the 1970s. This design is based on normalizing the data, making it more easy to use. It is also simpler to update data since it does not require changing certain sections of the database.

Most DBMSs can accommodate multiple types of databases through different levels of external and internal organization. The internal level is concerned with cost, scalability, as well as other operational issues, such as the physical layout of the database. The external level focuses on how the database is displayed in user interfaces and other applications. It can include a mixture of external views based on different data models. It may include virtual table that are computed using generic data in order to improve the performance.
