Compared with the fore-back-ground system, it brings many advantages which make the software standardization, let us predict the real-time ability of the software and make it easy to maintain 和过去的前后台的软件结构相比,多任务系统可以提供标准化、实时性可预测、软件易于维护等特性。
The resources include not only programs but also the methods, requirement specification, design construction, development tools and environment, testing and analysis data and maintain information, etc . it has been proved that software reuse is practical and feasible approach to realizing software standardization, raising software productivity, improving software quality, reducing development cost and shorting development cycle 这些软件资源不仅包括源代码,还包括软件开发方法、需求规格说明、设计结构、开发工具与支撑环境、测试分析数据和维护信息等。实践已经证明,软件复用技术不仅可以提高软件生产率和软件质量,而且也是降低开发成本、缩短开发周期的重要途径。
