Advantages of database management system
Less redundancy: - Database redundancy can be worked by using DBMS. This means that if we have to change the database, then this change has to be done at one place.
Data independent: - The data whose value we want to store or retrive is data independent.
Efficient data accessing: - Data can be easily stored and retrive using DBMS techniques.
Reduce application development time: - DBMS supports many functions which are common for many applications.
Security: - DBMS can access the application database.
Integraity (integrity): - Integraity constants uniquely identify value in database. There are two constations.
Disadvantages of DBMS
*The cost of hardware and software can be high.
*Staffs like DBA, application programmer, operators are required and they need to be trained for this.
Sometimes it is a very complex system.
*DBMS is very large software, so it requires a lot of space and memory in the system to run efficiently.
*As we know that in DBMS, all files are stored in the same database, hence the possibility of database failure is greater. Sudden failure can lead to loss of valuable data.
