Advantages of Database Management Systems (DBMS)
A Database Management System is the most applicable and credible computerized record-keeping system and structure. It is a repository or a container for collection of various computerized data files. The comprehensive purpose of DBMS is to authorize the users to define, store, retrieve and update the information contained in the database on demand.
At present, data has become an essential aspect of any organization. The systematic management of a high volume of data is a challenging affair to deal with. Obviously, DBMS is an advantageous record-keeping system.
Data Safety and Reliability:
- DBMSs provide several security tools and mechanisms.
- To protect the data from unauthorized access, DBMS provides authentication and access control.
- It offers encryption options to secure sensitive data, such as credit card numbers or any kind of individual data.
- Forms complete authority and dominance over the operational data.
- The Database Administrator can define authorization checks to be carried out whenever access to sensitive data is attempted.
Data Integrity and Consistency:
- DBMS applies rules and restraints on the data, ensuring that all data is precise, constant and consistent.
- DBMS can be programmed only to allow unique values in a specific field, averting duplicate entries.
- DBMSs provide various tools for data validation, such as check constraints and triggers.
- Intensifies the integrity and wholeness of the data.
- Intensifies the accuracy and efficiency of the data.
- Consolidated data control helps to permit the administrator to define integrity constraints to the data.
Data Accessibility and Regulation:
- DBMS provides a key to effective data processing and conversion.
- It allows for upgraded data accessibility and control.
- Authorized users can easily retrieve and manipulate data while assuring that the data remains consistent and accurate.
- DBMSs provide tools for managing concurrent access to the data.
- Ensures that multiple users can access the data simultaneously without corrupting it.
- Uses methods and strategies such as locking and transactions.
- Ensures that the data in the database is accessed and modified in a compatible, measured and controlled manner.
Data Backup and Recovery
- DBMS provides a strong framework for data backup and data recovery.
- Data backup and recovery is automatically taken care by DBMS.
- In case of a server crash, system failure or inesurity, DBMS restores the Database to its previous condition.
- DBMSs offers various backup and recovery options, such as incremental backups and point-in-time recovery.
- It uses techniques such as backups, replication and journaling.
