Membership 类表示会员的会籍信息,包括会员编号、会籍起始日期、会籍结束日期和会籍状态。Equipment 类表示健身房设备的信息,包括设备编号、设备名称、设备类型和设备描述。Workout 类表示会员的锻炼信息,包括锻炼编号、锻炼日期、锻炼时长、消耗卡路里和会员信息。Facility 类表示健身房的信息,包括健身房编号、健身房名称、健身房位置、健身房描述和健身房拥有的设备列表。MembershipDAO 类表示会籍信息的数据访问对象,包括添加会籍、删除会籍和获取会籍列表。
Membership 类与 Equipment 类之间没有直接的关系,但是它们都与 Workout 类有关系。Membership 类与 Workout 类之间是聚合关系,即一个会员可以有多个锻炼记录。Facility 类与 Equipment 类之间是组合关系,即一个健身房可以拥有多个设备。Facility 类与 MembershipDAO 类之间是依赖关系,即 MembershipDAO 类需要访问 Facility 类的信息来获取设备列表。
