What is a Database Management System (DBMS)? | Definition from TechTarget
Summary
In environments where multiple users access and modify the database simultaneously, a DBMS guarantees controlled transaction execution to prevent data corruption or inconsistency. End users and software programs are free from having to understand where the data is physically located or on what type of storage medium it resides because the DBMS handles all requests. Popular database models and management systems include the following: Sometimes referred to as a SQL DBMS and adaptable to most use cases, an RDBMS presents data as rows in tables with a fixed schema and relationships defined by values in key columns. As opposed to traditional row-orientated storage, a wide-column store is optimal when querying data by columns, such as in recommendation engines, catalogs, fraud detection and event logging. • In educational settings, DBMSes are used to manage student records, grades and academic information, making it easier to compute averages and produce report cards.
