Complex real-time systems need databases to support concurrent data access and provide well-deened interfaces between software modules. However, conventional database systems and prior real-time database systems do not provide the performance or predictability needed by high-speed, hard real-time applications. To address this need, we have designed,(More)
Complex client-server configurations being designed today require a new and closely coordinated approach to analytic modeling and measurement. A closed queuing network model for a two-tiered PeopleSoft 6 client-server system with an Oracle database server is demonstrated using a new performance modeling tool that applies mean value analysis. The focus of(More)
Analytical and simulation models of interconnected local area networks, because of the large scale involved, are often constrained to represent only the most ideal of conditions for tractability sake. Consequently, many of the important causes of network delay are not accounted for. In this study, experimental evidence is presented to show how delay time in(More)
On Line Analytical Processing (OLAP) aims at gaining useful information quickly from large amounts of data residing in a data warehouse. To improve the quickness of response to queries, pre-aggregation is a useful strategy. However, it is usually impossible to pre-aggregate along all combinations of the dimensions. The multi-dimensional aspects of the data(More)
This paper describes the application of database technology to medical information with the goal of providing medical and clinical researchers with the tools necessary to plan bioinformatics projects. Commercial database management systems were utilized, standard database design practices were applied, a user interface was created, data entered, and the(More)
New soffware engineering techniques and the necessity to improve the user interface in increasingly interacfive software environments have i!ed to a change in traditional software development methods. Methodologies for improvement of the interface design, an overview of the human factors element, and cost/benefit aspects are explored. Traditional software(More)
The Center for Information Technology Integration has undertaken a study of the potential impact of PeopleSoft software on U-M production computing environments, focusing on the measurement and modeling of the Peoplesoft 6 architecture in order to provide results useful in sizing various components of the M-Pathways campus deployment. This report describes(More)
