Component base software development methodology is the most important technological revolution of software industry in the past few years. Straightly to push forward software industry from taking handiwork as principle thing, gradually to get into automation assisting tool procreation¡¦s automation industry. Component base software development technology give way to business information system easy fabricate flexibly. System developer may assemble software components depending on user requirement. We can increase or subtract system components to modulate a section of system capability any time. But do not influence whole system, only contained a part of system components. This thesis brings up an object-process methodology to apply develop a business distributed information system. Using object-process methodology to find business objects from business process. We can divide system analysis into two parts and eight steps, to analyze the user requirement than to design information system to guide stable software objects and system framework. Through object-process business system helps we establish the model of the complex business system, mapping the real world activity or the abstract conception into system model. We can analyze and design distributed objects efficiently for distributed operation system environment needed. Proceeding to the next step, to transform software model and to seal up distributed component object module (DCOM), than to put DCOM into system application layer. Let the business information system flexibly and ample fitting in user requirement.
