In wide-enterprise information systems, the same entities (objects) play different functional roles during their lifecycle. Different users might have access to the same objects from different perspectives whether they are local or on remote sites. In the enterprise systems, the distributed applications suffer also from performance problem [3][15], [4]. The development and the distributed of these functional roles/views can be realized using one of the several aspect oriented software development techniques, in particular view oriented programming. Theses views are code fragments, which provide the implementation of different functionalities for the same object domain and theses views can be used as a units for distribution to improve performance issues. Therefore, using view oriented programming encompasses a combination of views or aspects, which can be distribute, activated, and deactivated dynamically. Consequently, this dynamic behaviour necessitates a model of distributed view, in which an object provides the implementation of the different view combinations required by clients and a security access model has to be developed for clients that they have different access rights/privileges to different views.

Beginning with the trials on lunar rovers' mobility, stability and trafficability, a research of simulate proving groundprogramming design for lunar surface was performed. Based on the analysis of characters of lunar rovers, we put forward a set of integrated and reasonable design of tests, which focused on over-obstruction, evade-obstruction, distance-obstruction, as well as path planning of lunar rovers. At the same time, we provided systematic layout of simulate proving ground, and clarified the detailed content of each sub-item. It affords basic knowledge of systematically testing performance of lunar rovers, and it serves well for the lunar exploration.

We present the jABC, a framework for model driven application development based on Lightweight Process Coordination. With jABC, users (product developers and system/software designers) easily develop services and applications by composing reusable building-blocks into hierarchical (flow-) graph structures that are executable models of the application. This process is supported by an extensible set of plugins providing additional functionalities, so that the jABC models can be animated, analyzed, simulated, verified, executed and compiled. This way of handling the collaborative design of complex software systems has proven to be effective and adequate for the cooperation of non-programmers and technical people, and it is now being rolled out in the operative practice.
