One of the main principles behind matching in OEDQ is that not every match and output decision can be made automatically. Often the fastest and most efficient way to determine if possible matches should be considered as the same, and what their merged output should be (where appropriate), is to look through the matching records manually, and make manual decisions.
OEDQ provides two different applications for reviewing match results: Match Review and the Case Management. The review application is chosen as part of the match processor configuration, and determines the way in which the results are generated. For any given processor, therefore, the two applications are mutually exclusive. The selection of the review application also changes some of the options available to the match processor.
It is possible to change the configuration of a match processor at any time, to switch between review applications, but the processor must be re-run before any results are available to the new application.
The review application to be used should be chosen based upon the requirements of the process downstream of the match processor and the strengths of each review application, which are detailed in the following sections:
The Match Review application is a lightweight review application which requires no configuration. It supports the manual review of match results and merge results, the persistence of manual match decisions between runs and the import and export of manual match decisions. If key information is changed between processor runs, any previously saved match decisions for that relationship are invalidated, and the relationship is raised for re-review.
The Match Review application is suitable for implementations where a small number of reviewers in the same business unit share the review work. It does not support group distribution or assignment of review work, and offers basic review management capabilities.
For more information on the Match Review system, please see the Using Match Review topic.
The Case Management application offers a customizable, workflow-oriented approach to match reviewing. Case Management groups related review tasks (alerts) together, to form cases. Cases and alerts can both exist in a number of states, with permitted transitions between them. Case Management also supports automatic escalation of alerts on a time-out basis, or based on other, configurable, attributes.
Case Management supports assignment of work to individual users or to a group of users, and more sophisticated review management capabilities than those offered by Match Review.
Case Management must be explicitly activated for each match processor that wishes to use it, and extra configuration is required to support the generation of cases and alerts.
Case Management does not support merge reviews.
