Design and Implementation of System Architecture in a Huge and Secured Online Transactional System

Abstract

Today's Web applications nced a platform that is fast, maintainable, stable and secure. This project work presents and implements an online transactional system architecture for handling massive and load conditioning demands, and concurrency of busy Internet secure services. The bottleneck of Web content delivery is not serving static content but dynamic content which requires data processing. For such web applications scalability can be provided by a third party solution that caches application data and can maintain high concurrency when the concurrent user quantities are unpredictable. We propose to use a database cache for offloading the demand on a database-driven Web service. This project work presents the design of a database cache. In this project work we also study the security-scalability tradeoff, both formally and experimentally. We begin by providing a method for statically identifying segments of the database that can be encrypted without impacting scalability. The system is designed and tested based on the present course registration system and grade submission system of BUET as a model university.
