Management information systems of large - scale enterprises are so complex that models are usually used during the analyse and designment . the object oriented programing languages and flatforms are widely used for mis construct 大型企業的管理信息系統通常十分復雜,人們經常借助模型來分析設計系統,而面向對象的程序設計語言和軟件開發平臺已經成為目前mis系統構建的主要工具。
Language recognizer generators are tools in common used both for system software and application software development . with the computers spreaded in china , the requirment to process chinese information increases with each passing day ; on the other hand , ada95 is the first iso standard of object oriented programming language ( oopl ) , in addition to adopting the characteristics of high efficiency and safety of ada83 , ada95 enhances the support of object oriented technologies , and therefore becomes the ideal prograrmming language for developing and maintaining the large , complicate and high reliability systems 語言識別器生成器是系統軟件和應用軟件開發的常用工具之一。隨著計算機在我國的推廣使用,對中文信息處理的需求日益增多;另一方面, ada95是世界上第一個得到iso認可的面向對象程序設計語言的國際標準,它繼承了ada83安全、高效的特點,支持面向對象技術,是開發與維護大型、復雜、高可靠性系統的理想語言環境。
