disadvantages of a DBMS

  • Danger of a Overkill: For small and simple applications for single users a database system is often not advisable.
  • Complexity: A database system creates additional complexity and requirements. The supply and operation of a database management system with several users and databases is quite costly and demanding.
  • Qualified Personnel: The professional operation of a database system requires appropriately trained staff. Without a qualified database administrator nothing will work for long
  • Costs: Through the use of a database system new costs are generated for the system itselfs but also for additional hardware and the more complex handling of the system.
  • Lower Efficiency: A database system is a multi-use software which is often less efficient than specialised software which is produced and optimised exactly for one problem.
