The role of propagation in database support for performance-modeling environments

The authors investigate the role of propagation in database support for performance-modeling environments (PMEs) and elaborate on the use of the active data model (ADAM) object-oriented design tool to design performance modeling applications that include propagation. ADAM was used to design a particular performance model including the complex interdependencies between the components of the model, thereby maintaining the consistency of data throughout the model. The analysis contains background on propagation and the performance models of interest, and a discussion of the benefits of propagation for PMEs is discussed by presenting a list of goals for the database support for PMEs and outlining two categories of propagations for performance-modeling data.<>
