Study And Realization Of Products Catalog Storehouse Based On ASP

The enterprise informization is a key to enhance its comprehensive strength and competivity on market. However, as a result of the large amount money investment in earlier period, the exorbitant maintenance cost in later period, the deficiency of the specialized technical talents and so on, domestic informization in small and medium-sized enterprises (SMEs) steps forward roughly throughout, which contributes to the schedule still at the scratch line in a whole. The organization and management of products and their respective components, the poor promotion of products and which in turn leads to the low rate of production and sale, marketing channel etc. highlight day after day in domestic SMEs. How to take advantages of the modern information technology, associate with exterior resources and management strength such as universities outside enterprise, the scientific institution, the experts from other enterprises and customers and so on to carry out networked organization and management of enterprise products catalog is one of important mentalities. This thesis focuses on design and realization of multi-organization's product catalogs based on ASP. The main contents include:1. An improved method of access control in the ASP system for multi-organizations is designed based on the prevalent Role-based Acess Control (RBAC) model. Resorting to the method of access classification, the system manager will ease himself from the heavy burden of granting the initial access. Encapsulation of user's access group by group is carried out using the JavaBeans technology in user's access examination, which solves the present network bottleneck by abandoning the traditional thought of "judging it only at time when it is used" in system access control.2. Combining the already mature technology in Java 3D, an extensible Enabled Tool Collection is proposed and designed, which includes a platform of products 3D demonstration based on models and pictures respectively, which realizes the mouse function of interactive respond simultaneously.3. An extensible ASP system framework is proposed, and the main function...
