20130253954 | SYSTEM AND METHOD FOR MANAGING CASE DATABASE - There is provided a system and method for managing a case database that can enhance the quality of information to be registered. Once a user performs an operation to request registration of a case, it is first searched whether or not a case that can be determined to be similar to the case has already been registered in a case database. A result of the search is then reported, while executable processing options determined based on the result of the search are also reported. If the case that can be determined to be similar has already been registered, the executable processing options include processing of registering as a new case, processing of registering by adding into an existing case, and processing of cancelling registration. If the case that can be determined to be similar has not been registered, the executable processing options include processing of registering as a new case and processing of cancelling registration.
