4 Must Know DBMS For Every DBA
A Database Management System, or DBMS, allows its users to create, read, delete and update data within a database. The management system works as an interface between users and/or application programs and the database to make sure that all data is well organized and easily accessible.
Within an organization, the DBMS manages three key aspects, the data, database schema and database engine and hence allows users to access modified and locked data. These three important aspects offer data security, concurrency, data integrity and all other uniform administrative procedures for remote DBA support.
Enjoy Logical and Physical Data Independence
A user can enjoy both logical and physical data independence through DBMS. It means the system can help users or applications by letting them know where all important data is stored. It provides application programming interface for the database. There is no need to modify programs by developers since all the changes will be made by the DBMS.
It has become popular in several industries and today more people are relying on these systems for their efficiency in improving data management within an organization. There are different types of it available in the market, but all can be broadly classified as:
Relational database management system – The product can be a bit expensive, but the system is adaptable for many cases.
In-memory database management system – This system is being largely used by corporate sectors for its tremendous work efficiency, fast response times and overall better performance compared to other DBMSs.
Columnar database management system – This system is well suited for all types of data warehouses comprised of a large number of the same kinds of data items.
Cloud-based data management system – Here, the operators of cloud services will be responsible for maintaining the DBMS.
