Disadvantage of DBMS

Although there are many advantages of DBMS, the DBMS may also have some minor disadvantages. These are:
  • Cost of Hardware and Software
A processor with high speed of data processing and memory of large size is required to run the DBMS software. It means that you have to up grade the hardware used for file-based system. Similarly, DBMS software is also very costly,.
  • Cost of Data Conversion
When a computer file-based system is replaced with database system, the data stored into data file must be converted to database file. It is very difficult and costly method to convert data of data file into database. You have to hire database system designers along with application programmers. Alternatively, you have to take the services of some software house. So a lot of money has to be paid for developing software.
  • Cost of Staff Training
Most database management system are often complex systems so the training for users to use the DBMS is required. Training is required at all levels, including programming, application development, and database administration. The organization has to be paid a lot of amount for the training of staff to run the DBMS.
  • Appointing Technical Staff
The trained technical persons such as database administrator, application programmers, data entry operations etc. are required to handle the DBMS. You have to pay handsome salaries to these persons. Therefore, the system cost increases.
  • Database Damage
In most of the organization, all data is integrated into a single database. If database is damaged due to electric failure or database is corrupted on the storage media, the your valuable data may be lost forever.
