摘要： 将面向对象软件建模的“抽象”原则具体化,扩展“抽象”的定义为广义表结构,从而建立了“抽象”演化分层结构图,提高了“抽象”原则的实用性。以此为指导,创建了四川省高速公路联网收费软件系统4+1抽象建模结构,在保证模型结构有足够柔性的同时,进一步提高了系统的可重用性、可修改性、可移植性等非功能特性。

Abstract: principle of object oriented software modeling. By expanding the definition of "abstract" to the data structure of generalized lists, it establishes the "abstract" layered evolving diagram, and therefore increases the practicability of the "abstract" principle. Based on the diagram, it sets up the Sichuan province expressway network tolling system 4+1 abstract modeling structure. The purpose is not only to ensure the inflexibility of the modeling structure but also to try to further enhance the system's non- functional characteristics, such as reusability, modifiability and transplantabiliy.
