SOA have been deployed as a mean to offer a better flexibility, to increase efficiency through reuse of services and also to improve interoperability by providing new opportunities to connect heterogeneous platforms. However, those benefits make security more difficult to control. Fortunately, new standards are proposed to treat this issue, but their current use makes the architecture much more complex...
Web services hold a great promise of implementing the B2B e-commerce by dynamically integrating business processes over the Internet.

In this paper, we proposed a method to transform the workflow processes into CCS, and the workflow process is described in activity network charts. For the first, we used CCS to describe the six basic logical relations of the workflow model, and then based on the basic expressions, we illustrate how to transform the whole workflow model to CCS process expressions.We provide the exact formalization...
To discover process models from event logs has recently aroused many researcherspsila interest in the area of process mining. Notwithstanding the interest and related efforts, existing algorithms are far from being satisfactory. For example, some researchers have proved that alpha-algorithm is capable of discovering the processes of the so-called SWF-nets without short loops; however, alpha-algorithm...
We analysis bank lending and trade credit, and compare them with another new source, that is inventory financing. And we give empirical evidence and conclude that trade credit is more important for small firms, but these two sources cannot satisfy all the financing demand, so inventory financing will be more help for the development of small firms.
Traditional research of software components mainly aims to components at the level of program and source code, due to which the coupling degree between the components and the runtime environments is hard to lower, thereby limiting the reuse ability of the component. The application level components containing comparatively integral granularity of business function are more suitable for a larger scale...
