设计一个图书管理系统，完成图书管理的基本业务； 基本要求： 1）每种书的登记内容要包括图书编号，书名，ISBN,作者，现存量（即：可借阅量）和库存量（即:书的总量），出版社等。 2）借阅者信息主要包括，借书证号，姓名，单位，联系电话等。 3）系统的主要功能如下： 采编入库：新购一本书，如果库中已有这种书，库存量和现存量增加；如无该书则新建该书的信息； 借阅：如果现存量大于零，则借出一本登记借阅者的借书证号，借书日期，归还期限。并改变现存量。 归还：删除借阅者的相应借阅记录，改变图书的现存量。 查询：可查询相关图书的信息；也可查询借阅者借阅的相关信息，借阅者的借阅信息要求按图书的ISBN排序。
