Disadvantages of Database

The following are some of the disadvantages of database:
1. Higher data processing costs
The database system causes higher data processing costs. This is due to the strict and elaborate procedure for data access, updating and processing.
2. Increased hardware and software costs
It requires more direct access memory capacity, greater communication capability (including communication software), and additional processing power. This increases the hardware and software costs.
3. Data insecurity and integrity
Most of the security and integrity problems are related to the fact that many users have access rights to the database. Elaborate security systems are implemented to protect the database and to prevent unauthorized access.
4. Insufficient database expertise
Database technology is complex. Most organizations do not have enough personnel with necessary expertise to implement and manage database systems.
