Database Management Systems

DBMS or Data Management Systems can grant an access for multiple users to an specific database. DBMS can be very reliable nowadays because of many stuff like data security, storing and organizing data, protecting data integrity, backing up data and recovering it quickly and many many more capabilities that are very useful. what's more is about the consistency, database management systems can perform consistently without causing problems because it is achieved by establishing rules. Lots of businesses can increase their access to data, they can use it to track their records from the past and think of a best solution for their success and also to prevent them from their past mistakes.

C. Disadvantages of DBMS

While we have advantages of DBMS, we also have its disadvantages. Database Management Systems main disadvantage is the cost, DBMS cost increased because of the processing requirement to manage all the data we have, while we have lots of data, we need more capacity on our storage to store all the data, and more capacity of storage costs us more. And I'll also include the DBMS failures. DBMS can fail anytime, what we need is a lot of maintenance and constant power, if the database fails then the whole system will fail and our data or any organization will be affected, their data may not be saved, it may be deleted, and etc. I may also include the complexity, it requires a lot of staff and software to do so, they all need the knowledge of the DBMS, failure to do so can be led to data loss or wrong management of data which could affect any organizations data.
