We consider the problem of improving the efficiency of query processing on an XML interface of a relational database, for predefined query workloads. The main contribution of this ...
Predicting the performance of a system before it is built is a highly desirable goal, but one that is rarely achieved. This paper examines performance problems and issues within in...
This paper presents an analytical performance prediction model that can be used to predict the speedup and similar performance metrics of four approximate string searching implemen...
