The following are the risk & expenditure of database-


(i) Organizational Conflicts- Pooling data in a very common database could not be politically feasible in some organizations. Certain user groups may possibly not be willing to relinquish control over their data to the extent needed to integrate data. Moreover, risk involved in data sharing, as in that one group may damage another group''s data and potential system problems that might limit a group''s access to its own data could be viewed as more troublesome than beneficial. Such people problems may perhaps prevent a effectual implementation of a database system.


(ii) Development Project Failure- For a range of reasons, project to develop a database system could fail. Sometimes management was not fully convinced of value of database system in first place. A database project to seem to be taking too long may be terminated.


A project large in scope may be approximately impossible to complete in a reasonable time. Again, management and users become dissatisfied and project fails. Throughout course of a project, key personnel might unexpectedly leave a company. If replacement personnel cannot be found, then project might not be successfully completed.
