Replay the Execution History of Rule-Based Information

Software systems in health care, such as disease and medical-record management, or financial applications, such as customer relationship and portfolio management, have very often a temporal nature. Information is specified in form of rules as a pre-step for monitoring the changes of interest in the application. Managing such applications requires to provide replay support for managed information at any specified review period. This paper presents a replay support method for information formalized as rules. This method is based on an XML-based model and a replay query language for the rule-based information. We introduce the model and the language using a clinical case study, and evaluates the storage efficiency of the model and the performance of the query.
