Companies, institutions, and local authorities look for virtualizing all provided services to obtain more profit in terms of productivity, profitability, quality of service, traceability. The main issues are the identification of problems to solve and the choice of adapted solutions. To build these ones, functional and technical profiles must communicate to understand precisely the domain, the problem,...
The process of modeling concerns itself with the extraction organization of knowledge unambiguously. The rapid advancements in information processing systems are steering engineering research towards the development of intelligent systems. Though the aim of modeling is to provide the human user of the environment to represent knowledge that is convenient to operate, Modeling has become indispensable...
This paper addresses a major issue with information systems: personalized access to information. In today's information technology environment, which is experiencing such considerable data growth, where user roles and needs are increasingly heterogeneous, and where mobile systems develop with ever increasing rapidity, it has become important to develop a personalised system, which allows the provision...
Integrated systems enable capabilities and performance that independent systems cannot offer. Systems integration, or enterprise application integration, establishes linkages between different computer-based information systems and databases and thus is often required to achieve business integration.There is no conceptual modeling technique designed to help systems integrators elicit, represent, and...
Conceptual models are designed to express user requirements of information systems in a formal and self-explanatory manner from a business user's point of view. Furthermore, they should contain enough information for IT staff to use them as a basis for technical deployment. Within the domain of OLAP information systems, multidimensional data models are used to translate the specific user requirements...
Aiming at Bayesian rough set model, some new concepts of knowledge reduction are denoted such as the upper approximation reduction and the lower approximation reduction, the upper approximation discernible matrix and the lower approximation discernible matrix, the judgment theorems with respect to those reductions are obtained, from which we provide new approaches to knowledge reductions in information...
The notion of workflows has evolved from a means to describe the flow of paperwork through an organization to a more abstract and general technique used to express best practices and lessons learned in many application domains. When putting workflow definitions into practice, it is important to stay informed which tasks are currently performed, as this allows detecting slipping schedules or unwanted...
Digital Earth (DE) is a virtual presentation of the planet based on geographic coordinate, and is an information system with tremendous amount of multiple resolutions and multiple scales data as shown in multiple dimensions. It can visualize the real earth and represent historical phenomena in digital way by using the large amount of data of the earth, and utilizing the computer techniques, image...
