Develop High-Strength Concrete Expert System Based On COM Component

With the development of computer technology, new technology and method will emerge more and more. From 00 to Generic Programming, Template Metaprogram, Generative Programming; from COM to COM+ , Web Service; from STL to ACE, Boost, Loki, ICE. Every time I read and fell these, I find it' s so wonderful. In this paper, we discuss these new technologies with expert system. From the actual requirement of system design, based on expert system' s concept, using COM technology, we build one of the high efficient, flexible, loose coupling and high integration High-Strength Concrete Expert System, and do some research on the core technologies in this paper.Simply introduce expert system' s characteristic and excellence. This task' s aim and meaning, the development of expert system in concrete domain. According to one class one responsibility and enforcing the reuse, discuss the system design of High-Strength Concrete Expert System, through compare template method with derivation and Hard coding, discuss a new construct method based on the GenScatterHierarchy class in Loki lib. Although GenScatterHierarchy is complicated, it exposes a new landscape in front of us.Introduce the primitive element in COM. for example, Interface, HRESULT GUID and the three member function of IUnknown Interface. Through ClassFactory particularly introduce COM component' s construction. Use ActiveX control we construct the interface of High-Strength Concrete Expert System.Discuss the equation model that the need fitting arguments reference to in this System, corresponding linear fitting algorithm' s reasoning and implementation. Implement the generic algorithm of the linear equation with template idea nested. Finally discuss the refinement of system' s code, based on the rules :one function one responsibility, use class to encapsulate the pointer which point to heap array and so on.Above the high efficient, flexible, loose coupling and high integration High-Strength Concrete Expert System, makes use of COM component technology and together with other method. And the same time, it provides a brand-new mode for the constructions of High-Strength Concrete Expert System.
