Multiple Date Versions in Database SystemsReport
A prototyping environment is a valuable tool for evaluating new techniques and design alternatives for database systems prior to the actual implementation of the system. Using such a prototyping tool, the characteristics and possible performance benefits of maintaining multiple data versions with time-stamp based scheduling are investigated. In addition, the characteristics of a database system employing a multiversion concurrency control mechanism in a real~time environment are explored. This research is focused on how the availability of multiple data versions may be used in order to better meet the timing constraints of the system. A scheduling algorithm which incorporates the consideration of the temporal requirements in its scheduling decisions is presented.
