A computer implemented system is provided in order to manage the exchange of information through three databases. The system is particularly useful for an appraisal management environment or other environments, which require an exchange between individuals in two or more categories such as consumers and appraisers. According to the preferred configuration, the system manages a database of real estate appraisals job postings. Each posting is stored in a job record, and the system is capable of searching on a plurality of keys in the consumer record to identify a real estate appraiser job record suitable to a particular appraiser. The system then facilitates creation of an appraisal record and designation of the appraisal record for an accessible appraisal base or a selected job record. The system permits query of a job base in order to identify real estate appraisals jobs for appraisers. Finally, this system prevents collusion between the consumer (mortgage company) and the appraiser by creating a mutually exclusive event.
