Performance evaluation of DBMS is a major issue since it is generally difficult to model experimental and performance analysis results. In this paper, we propose an application framework that provides a model, a methodology and a common platform to implement database evaluation analysis tools. Inspired on a conceptual UML model [14], this application framework provides a much more detailed model that allows capturing the complex structure of DBMS modern software. We use a recent work [1] about the implementation of a new data page layout to illustrate the instantiation of our framework.
