The data in international business management exhibit salient features of massiveness and heterogeneity. Users often have the requests for range query, which further introduces the complexity and increase the costs of system execution. In order to address this problem, we propose an R-tree based scheme, which can efficiently meet the needs of carrying out range query. The basic idea is to build a...
The IOT is a huge and widely distributed the Internet that things connect things.It connects all the articles to the internet through information sensing devices. It is the second information wave after Computer, Internet and mobile communication network. With the rapid development of the Internet of Things, its security problems have become more concentrated. This paper addresses the security issues...
The paper proposes one adapt workflow model. We first study the model's execution and control mechanism. Then we study the concept of data association and control association, and use it as the basis to solve the problem of workflow correctness and consistency. We also research dynamic modification and the consistency transformation between the workflows. From the aspects of control flow and data...
With the development of the electronic commerce (e-commerce), the untraceable electronic cash is an attractive payment tool for e-commerce, because its anonymity property can ensure the privacy of spenders. Recently, Ziba et al. proposed a new untraceable offline electronic cash system. The authors claimed that their scheme can detect a malicious consumer who spends a coin more than once. In this...
Numerous transaction models have been proposed to mainly address the problems posed by advanced database applications in recent years, but only a few of these models are being used in real commercial products environments. We explore the complexity of workflow and show that, in many aspects, transaction models are a subset of workflow models and how traditional transaction processing can be incorporated...
Different from the traditional model, mobile workflow is a process in which one or more mobile instances migrate continuously and utilize local workflow service to execute their tasks. This paper introduces the mobile workflow management system and proposes the active service of mobile workflow. By using the theory of small world in society, a modeling mechanism based on business friend domain is...
Currently, Self-study Examination has become an important part of the social examination, but the features of self-exam such as dispersion, complexity and diversity make itself difficult to meet the needs of the examinees and the needs of information management. Therefore, this article adopts the idea of cloud computing to analyze the requirements of self-exam information, and presents a cloud computing-oriented...
This paper focuses on usage intention of the e-commerce based on ATM model. After empirical analysis, the following conclusions were made: Customer usage attitude has a significant positive impact on customer usage intension; customer perceived usefulness, perceived ease of use and perceived risk would significantly affect usage attitude. At the end, this paper proposes related suggestion about e-commerce.
In this paper, we develop a fire administrative management system based on the JSF framework and EJB3.0 technology. The system which uses four-layer architecture makes a progress in the implementation, compared with three-layer structure based on the mode of B/S in the past. By using Hibernate to accomplish the mapping between the object and relational data, the efficiency of web application development...
A radio monitor station (RMS) collects the radio signal information of a large range of frequency for the management of radio bandwidth usage. To meet the challenges of large dynamic data, we have developed a domain specific management information system (MIS) for the radio monitor stations. The system design and implementation are described in the paper. An algorithm is provided to work with the...
With the fast development of the information technology and enterprise business, the traditional management system based on three-tier architecture could not satisfy the need of enterprises. In this paper, we analyze the shortage of the traditional management system based on three tier architecture and bring forward a new solution of enterprises ERP which is based on the six-tier architecture.
In this article, the queuing theory is applied to study the problem of journey arrangements. Primarily, with the analysis of stochastic processes, we draw the conclusion that the arrival of tourists conforms to the Poisson distribution and the camping time also complies with the general independent and identically distributed law. As each camp can be seen as the selectable service counter, we determine...
In this paper, we research the secure management of business process, and propose a access control model which could authorize the data object. Based on the model, a role analysis algorithm that could support the dynamic assign of task is given. The algorithm considers different instance environment of business process, and supports dynamic assign of tasks, which could improve the adaptability and...
With the development of computer hardware and signal processing technology, petroleum geophysical exploration requires high-resolution processing of seismic data. This article, by using synthetic data and real seismic data re-sample and resolution test in conventional seismic data processing, conducted analysis and concluded that re-sampling does no harm to the signal from two samples to one sample...
In order to meet the growing business requirements about energy consumption (energy and water consumption), it is necessary to construct system about energy consumption in Petroleum Enterprise. Because of its advantages in high degree of flexibility and reusability, service oriented architecture becomes a preferred architecture. Through discussion about service oriented theory and related technique,...
Baseband transmission system have an irreplaceable role in the digital transmission system, its scope of application to penetrate into the network communication satellite communications, monitoring control, mobile communications, digital television, digital telephone life, science and technology in all aspects with the development of technology, thus increasingly becoming a key technology in the digital...
With the development and popularization of Mobile Internet and smart phones, mobile online shopping as a typical application of mobile e-commerce began to rise. The evidence is from Chinese mobile phone users. The article tests the conceptual model with Theory of Planned Behavior (TPB) by Questionnaire and Structural Equation Modeling (SEM) with Partial Least Squares (PLS). The analytical results...
