摘要:
针对应用软件开发中有大量属性的实体对象的管理、以及与外部数据源批量数据交换等需求的普遍性和实现的相似性，本文提出了基于元数据的统一实现方法，包括一种以元数据为基础的面向对象设计方法，以及以Excel为中介的通用数据批量交换处理框架。该方法提高了软件设计的抽象化水平和适应需求变化的能力，实际系统验证了方法的可行性。The management of entity objects with large number of properties and mass data exchange with external data source are common requirements in lots of application software development, while its implementations are very similar. A metadata-based unified implementation scheme is proposed to mitigate the duplicate code and to improve productivity of the programmer. The scheme addresses an object-oriented design paradigm, and a general mass data exchange framework with Microsoft Excel as mediator. The proposed methods improve the abstraction level of software design and the adaptability to changing requirements, and practical applications validate the feasibility of the methods.
