Geographical centralized e-commerce has a lot of defects. Based on the characteristics of P2P and Web Services technology, a decentralized e-commerce architecture is proposed in this paper, which can solve the problems such as the difficulties of resource reorganization, cross-platform, database maintenance and so on, which can hardly be settled in existing geographical centralized e-commerce. So...
The evolution of computer is started from human dependent to self-management. With the development of technology, people want to manage the complex systems in an efficient and reliable manner. Database Management Systems (DBMSs) started from the single user with limited operations; and with the passage of time more functionality is added to meet the need of the users. Maximum number of operations,...
This paper presents an architecture and a field implementation for a flexible and scalable distributed access control and management system, with application to the educational environment. The distributed control modules are developed based on embedded systems. Embedded systems are becoming increasingly common due to the fast deployment of advanced microcontrollers offering high processing speeds...
The project deal with architecture design, system development and testing of software framework for data management and scheduling of personal sources in home care agencies. Development is started from analyses, over proposal, implementation to resulting testing of application, thereby try cast over whole problems software engineering. System consists of the three main parts PC application, mobile...
As electronic patient record (EPR) is the basis of clinical information and the core of a hospital information system (HIS), the research on EPR is an important element of HIS and digital hospital construction. Based on B/S architecture, a three-layer EPR management system is presented. Its expandable, maintainable and secure B/S system architecture is cost-effective and is developed with Eclipse...
Systems biology research demands the availability of tools and technologies that span a comprehensive range of computational capabilities, including data management, transfer, processing, integration, and interpretation. To address these needs, we have created the bioinformatics resource manager (BRM), a scalable, flexible, and easy to use tool for biologists to undertake complex analyses. This paper...
This paper analyze the structure and network security strategy as well as expounding the key technologies and methods based on characteristics of small town's e-government system. Its discuss the main difficulties of database access and network security of small town's e-government system. After a case of e-government system is studied in Hengdian (a town in Zhejiang province), solutions are put forward...
Some burgeoning web applications, such as web search engines, need to track, store and analyze massive real-time users' access logs with high availability of 24*7. The traditional high availability approaches towards general-purpose transaction applications are usually not efficient or economical enough to store these high-rate insertion-only archived stream data. This paper proposes RAIDB5 (Redundant...
Crowd simulation can be considered as a special case of virtual environments where avatars are intelligent agents instead of user-driven entities. These applications require both rendering visually plausible images of the virtual world and managing the behavior of autonomous agents. Although several proposals have focused on the software architectures for these systems, the scalability of crowd simulation...
Data management in mobile computing environments poses great challenges to the database researchers. One of the important challenges is to provide a data replication solution that maintains the consistency and improves the availability of replicated data. This paper addresses this problem for large scale distributed information systems that operate in mobile environments. Our solution represents a...
In order to establish collaborations between different clinical research networks, a Web-accessible database was set up at the Hospital Clenico Universitario of Valencia (Spain), adapted to the analysis protocol and monitoring of patients who have undergone an acute myocardial infarction. Designed mainly with MySQL 5 and PHP, it offers several advantages when compared to either FileMaker or MS Access,...
