Cloud system management is complex due to their diversity and frequent runtime changes. Cloud systems were previously managed through cloud specific management tools that focus on optimising technical metrics, such as performance. However, business users care business metrics (such as cost and revenue) more than technical metrics. To address these issues, this paper proposes a unified business-driven...
Ajax-based technology plays an important role in RIA (rich internet application). Meanwhile, Ajax-based three-tier architecture is a classic architecture in software development industry. Study shows that the data access layer and the business logic layer can be designed as universal modules and the presentation layer can be divided into specific module and universal module. As universal module is...
Traditional workflow design tools which only provide the choreography of simple flow chart and do not provide a graphical configuration for access to a service, are unable to meet user demand for services. The article expands the Activiti Designer open source framework. It maintains communication through the bottom of the enterprise service bus, provides the registration services (OSGI, WebService,...
Following our previous research results, in this paper we provide two authoritative application scenarios that build on top of OLAP, a middleware for parallel processing of OLAP queries that truly realizes effective and efficiently OLAP over Big Data. We have provided two authoritative case studies, namely parallel OLAP data cube processing and virtual OLAP data cube design, for which we also propose...
The design of class in the different layer is one of the most important works in software development based on three-tier architecture, however, the methods of component are the core of class and the characters of the function (component method) in different layer are different so to find out these characters and to form the design strategy of component method called function in this paper is very...
Big data as another revolution of information technology is happening and has a huge impact on many fields of the society. In the military communication field, massive and multi-source data with explosive growth of operational command, operation and maintenance, meteorological environment provides the information source for data analysis in "information war" era. In order to improve the...
The thermal power system become more complex as it develops to the direction of large-scale. This brings high efficiency as well as brings much hidden risk. Once the failure appears, less leads to the decrease of operating load, more leads to catastrophic shutdown, and even damage the unit equipment. Therefore, the research on the real-time temperature on-line monitoring system for thermal power units...
With development of business process management technology and information technology, we can simulate business processes. How to describe business process by structural language and check business process model are the issues. We develop a business processes system by SOA and model business process actions by Pi-calculus and check the model by MWB.
Long period of petroleum exploration has accumulated mass materials of multi-source and multi-scale correlated with geographical position, including seismic, logging and geological data, etc. However, the present management system of the petroleum company cannot integrate and manage these materials effectively, making it difficult to organize and share the information. With the application of GIS,...
Distributed computing, a paradigm often used for building business applications, enables a task to be performed by combining the efforts of multiple processes. The processes can be running at different locations, and on different types of computers. So research on EAI Platform System is very useful work. In this paper, we gives an overview on the distributed computing problem in an integrated application...
The widespread use of campus cards in high schools brings the students convenience both in study and life. But they can't query and transact the business related whenever and wherever possible. The purpose of Campus Card SMS Platform based on MAS is to help the students know the use or transact the business related in time through text messages from cellphones or other mobile terminals. This paper...
In this paper, we focus on the storage schema, encoding/decoding and data compression algorithm of ArcSDE vector feature models in Relation Database Management System (RDBMS). Further, Based on ODBC database accessing techniques, we discuss systematically and implement method for direct access to the ArcSDE vector feature data which is stored in SQL Server 2000 RDBMS with the C++ programming language...
Aimed for the problem of Webservice needs to publish multiple services when the Webservice provides some business methods in the specific domain, a new design of Webservice is presented, which only publish one Webservice and the real business methods requested come from that server parsing client's message, instead of each business method is published as a WebService. This design makes the release...
Mobile workflow is an inevitable outcome of the development of the computer technology and wireless communication technology. we analyze the Web service interface and news driven collaborative mechanism on the basis of the study of the mobile workflow structure model, and especially we analyse the cooperative rules classification and BPEL description method; In order to the apply for opening laboratory...
This article analyzes network management system based on C/S and B/S architecture. Incorporating with advantages of two types of architecture, a design idea is brought up for building a network management system based on J2EE and RIA technology. Major common functions for network management system are designed and realized through research and analysis of data transmission mechanism among each layer...
Current advances in portable devices, wireless technologies have created a mobile computing environment which is characterized by a large scale of dynamism. But mobile computing is quite different from traditional middleware while addressing the dynamic and pervasive aspects of mobile systems. This paper represents the experience of our project related to next generation middleware systems, with high...
Resource Date Center (RDC) for labor and social security bureau (LSSB) was come into being following the need of information sharing and social service of networks. Progress on information technology led to unfitness of current theoretical architecture for traditional data center. In this paper, we analyzed the proposed an integrated solution called typical labor and social security management information...
In Guangzhou Higher Education Mega Center (HEMC), there are more than 30 million high-quality college teachers and students. With the development of wireless technology and mobile phone technology, as well as the continuous deepening of education reform, solely Internet-based information system has been far from enough to meet the needs of the HEMC's development. After deep analysis of the actual...
To meet the new requirements drove by nowadays E-commerce for the signature schemes, a new threshold signature scheme is proposed from bilinear pairings based on improved short signature scheme, which realizes a single signing member can accomplish signature efficiently. The analysis shows that the scheme serves properties of non-masquerading and auditing, the members can be added and revoked dynamically...
This article analyzed the possibility of mobile commerce based on short messages in detail through combining SMS in mobile communication with the enterprise commerce application. Moreover, discussed the SMS application in mobile commerce according to the flexibility and universality of the SMS, and designed a mobile-commerce architecture based on commerce application server and short messages process...
