In this data-dominated and data-driven world, accurately recording, storing, updating, and tracking data is vital to any company. Database management systems (DBMS) are important in the creation and management of businesses.
For companies and businesses, DBMS are important for handling multiple types of data in a highly effective manner. The recorded data managed by DBMS can include student information, payroll, employee records, accounting, project management, inventory, and etc. These database systems are created to be extremely versatile in handling information.
What is a Database Management System?
To put it simply, database management systems are collections of programs that manage and control stored data in the database. This means it manages the database structure and it also controls the access of the data in those stored files.
When the DBMS receives requests, converts them to the complex processes required to fulfil those requests within the system. However, these complex processes are not visible to the end-users.
Benefits of Database Management Systems
Data sharing
In the database, multiple users can share data among themselves. While there could be different levels of authorisation of access, it’s still advantageous when authorisation and access can be easily customisable and shared to even remote users.
Data redundancy reduction
A database avoids repeating data stored in diff locations in the system or across multiple systems. It reduces copying of the same file and helps save storage space to give way to other important data. Any change is reflected immediately after encoding since there’s a single database.
Data integrity
It’s advantageous so that the data stored is accurate and consistent. It’s crucial because there are multiple databases in a DBMS, and all of them contain data that is visible to all authorised users. So it’s important to keep them correct at all times.
Data Privacy and Security
Only authorised users of the database can access them according to its privacy restrictions. The database manager can give specific authorisations for each user to ensure security and integrity of the data stored across the DBMS. For example, your company system allows you to view your clock ins as well as attendance but you cannot change any detail from it, aside from your HR manager. So, you only have limited access to viewing and not changing.
Recovery and Backup
The DBMS also takes charge of backing up data and recovery. Users aren’t burdened with backing up their data so often since the system does the work. In case of crash and system failure, the system restores the database, too.
