The various cost and risk factors involved in implementing a database system are:
High cost: Installing a new database system may require investment in hardware and software. The DBMS requires more main memory and disk storage. Moreover, DBMS is quite expensive. Therefore, a company needs to consider the overhead cost of implementing a new database system.
Training new personnel: When an organization plans to adopt a database system, it may need to recruit or hire a specialized data administration group, which can coordinate with different user-groups for designing views, establishing recovery procedures and fine tuning the data structures to meet the requirements of the organization. Hiring such professionals is expensive.
Explicit backup and recovery: A shared corporate database must be accurate and available at all times. Therefore, a system using on-line updating requires explicit backup and recovery procedures.
System failure: When a computer system containing the database fails, all users have to wait until the system is functional again. Moreover, if DBMS or the application program fails, a permanent damage may occur to the database.
