Architectural Impact on Performanceof a Multilevel Database

چکیده
Since protection and assurance are the primary concerns in MLS databases, performance has often been sacriiced in some known MLS database approaches. Motivated by performance concerns, a replicated architecture approach which uses a physically distinct backend database management system for each security level is being investigated. This is a report on the behavior and performance issues for the replicated architecture approach. Especially , we compare the performance of the SINTRA 1 MLS database system to that of a typical conventional (non-secure, single-level) database system. After observing the performance bottlenecks for the SINTRA, we present solutions that can alleviate them.

متن کاملTowards the Design and Implementation of a Multilevel Secure Deductive Database Management System
In this paper we describe a preliminary design and implementation of a multilevel secure deductive database management system (MLSIDEDBMS). In particular, logic as a dara model for multilevel databases, reasoning across security levels, architectural issues for an MLSIDEDBMS, and a prototype implementation are discussed.

It is now evident in the literature that the information and communication technology (ICT) has a positive and significant impact on the productivity and economic growth. Most studies in this area, however, are limited to the developed countries. Given different regulations and economic conditions, and also an increasing trend in allocating resources to ICT in developing countries, it is import...
متن کاملImpact of architectural variables on evacuation time of a classroom in emergencies
Investigating the process of evacuating people from a space such as a stadium, theater, or classroom is very interesting not only for managers and relief organizations but also for designers and researchers in the field of architecture. In this study, the evacuation process of a classroom with 42 students in emergencies was investigated by computer-based simulation using the A* algorithm and th...
