A database management system is used to let employees and owners access a large variety of information from a specific location like a computer. It allows access to specific information based on the user's credentials.
A database management system is important in industries that require a large amount of information to be stored and accessed by a variety of users. The users can access all of the information from nearly any location without having to physically go to where the data is stored at. The database management system enables a large amount of users to access the data and makes it ideal for accessibility. It is also able to protect the integrity of the data by storing it and organizing it in specific ways using codes that are predetermined by the administrator of the program. It may be able to block changes to data based on the nature of the business and the person accessing the data. In order for users to be able to view, change or replicate certain parts of database systems, they must have the proper credentials that are determined by the administrator of the program. Administrators can have complete control on who is able to see what information on the database management system.
A DBMS controls the database schema, which is directly responsible for defining logical structure, the database engine, which facilitates the access and modification of data, and the data itself. The three main components ensure data integrity, security and concurrency. Examples of DBMS include: banking systems, inventory systems and automated library systems.
