Description: 《数据库设计》课程设计 一、 设计目的 数据库设计是一门应用性很强的学科,在学习时必须使理论与实践相结合。课程设计的目的是通过实践使同学们经历到一次综合训练,以便能较全面地理解、掌握和综合运用所学的知识。 二、 设计任务与要求 (1) 对实际系统进行分析,写出需求分析说明(数据需求和事务需求)。 (2) 概念结构设计 说明本数据库将反映的现实世界中的实体、属性和它们之间的关系等(E-R图,可以用基本E-R图或扩展E-R图)。 (3) 逻辑结构设计 将概念结构映射为数据库全局逻辑结构(关系模型),包括所确定的关键字和属性、重新确定的记录结构和所建立的各个表文件之间的相互关系。 三、 设计环境与工具 要求使用辅助设计工具,如Power Designer或者ERWin等,转换为:SQL Server、Access或其它的DBMS数据库(不作统一要求)。 四、 设计步骤 参考《数据库设计实例指导书》 五、 设计题 教材P58面:3.8课程设计A、B、C任选一题 六、 设计成果 设计结果以书面形式于17周交付。 七、 成绩评定 (1) 独立完成 (2) 文档完整 (3) 满足用户需求 这是研究生数据库课程设计-"Database Design," a course design, and designed to database design is an application-oriented subjects, the study of theory must be integrated with practice. Curriculum design is through practice so that the students experienced a comprehensive training, in order to give a more comprehensive understanding and comprehensive use of the knowledge acquired. Two, design tasks and requirements (1) to the actual system analysis and write demand analysis (data needs and services demand). (2) design concepts to describe the structure of the database to reflect the real-world entities, attributes and the relationship between them, etc. (E-R, you can use the basic E-R or expand E-R). (3) logic structure design concept mapping overall logic to the database structure (model), including the s
