Study On Frame Design Of The Highway Construction Management System Based On COM

With the national economy maintained a sustained, rapid and sound development, the strength of infrastructure investment is increasing, especially in the high grade highway construction investment. Especially the economic crisis, in order to stimulate domestic demand and reduce the effects of economic crisis,our country expand the strategy of infrastructure construction. , And because of long construction duration of the highways,widely coveraged and low efficient only by manual work, it is necessary to develop computer information and technology,vary highway systems are applied to the highway construction. However, the current market of the main system fails to take he depth of analysis before the software design period,not depth understand of the process of highway business,taking not advance computer technolygy, so cause the system not having maintenance, scalability and reusability, difficult to obtain economic returns in the implementation process. And business systems developed independently, and independent operation of data information sharing hard to statistics data and in the end it is difficult for the management of highway construction.This article in full analysis the functional and business processes of the highway business systems , extract the common need, then come up with three major.one is unit of subentry project amount list,one is project division, one is project entity. Then on this basis,with overall research target on the highway construction system and analysis framework between the object-oriented(OO) method and COM method ,put forward ideas about the general framework design of the highway construction system based on COM, including three common component, a link between the components, each business component based on common components. Then, analysis and design the various component object model., including unit of subentry project amount component object model , project division component object model, project entity object model. Component object model needs have highway projects database to support, so in the sixth chapter, analysis the database design of each object-oriented(OO) highway projects'component object model detailly.The research of frame of highway construction management system has positive influence on improving maintenance,scalability and reusability of the business systems , and will implement the data sharing, operation and integration among business systems and then improve economic performance and market competitiveness.
