我想创建数据库,我将在其中输入人员以及此人注册的项目/计划。
例如:
人:Max Stewart
- Project: Website
-- Program: What is website?
-- Program: How to create website?
-- Program: What do I need to create website?
人:Roger Federer
- Project: Car
-- Program: Which car brand should I buy?
- Project: Website
-- Program: What is website?
如果我想查看加入的人(项目:网站和计划:什么是网站),我将获得列表:
- Max Stewart
- Roger Federer
此列表实际上是ms-access中的报告..
到目前为止,我已经完成了
我有3张桌子:
Person (PersonID, Person details...)
Project (ProjectID, ProjectName)
Program (ProgramID,PersonID, ProgramName, StartDate, EndDate)
关系:
Person -> (one-to-many) -> Program
Project -> (one-to-many) -> Program
问题是每次我想将另一个人添加到同一个程序中(程序以新ID开头,这样就是新程序)
对此有何建议?
