Information technology for e-governance system could yield great benefits and modernization of the different government sectors. The experience of e-governance system in a number of developed and developing countries has shown that information technology can provide greater service delivery with great quality. The purpose of this paper is to better understand how agile principles, specifically eXtreme...
The development and application of the traditional GIS, as a platform, have long been heavyweight, expensive and non-public. Nowadays, with the explosion of Web2.0, they are facing challenge. An agile, lightweight, reusable GIS is now in need. This paper promotes a solution to meet this need. Based on SOA, the solution fulfills the concept of Web2.0 and software2.0 and designs an open architecture...
This paper presents some lessons learned from complex field experimentation with SOA initiatives over the past 5 years. These were large-scale experiments with nodes in several countries and 100s of participants. Tested scenarios included support for coalition and civilian agencies for disaster relief in international emergencies. SOA technologies were tested as communications and information resources...
Automated negotiation has become the core of the intelligent e-commerce. Traditional research in automated negotiation is focused on theory about negotiation protocol and strategy. However, the application of automated negotiation system has lagged far behind. This paper discusses the reason for such a situation, and proposes a technology roadmap for the development of automated negotiation system...
Along with the development of the modern information technology, a lot of wide-area information such as WAMS (wide-area measurement system) information, need to access to the energy management system (EMS). But all the present EMS system architectures are designed in a tight coupling way which is inflexible and closed. This causes these systems hardly to benefit from this information. A new EMS system...
Web services are the best way to solve cross-platform, cross-language, loosely coupled distributed systems in web environment at present. But because of some non-functional attributes such as authorization, security, transaction, logging, etc. in web services, the adaptation and reuse of web services are decreased. It is difficult to maintain and extend SOA-based applications which are composed of...
This paper suggests a holistic design and development method combining test-driven and model-driven development for SOA architectures. It uses test-driven development on component level and model-based testing on system level. Moreover, monitored performance parameters during test execution serve as input for a model-driven performance analysis of the business application, providing early indication...
