这是一个简单的数据库，可用于维护借阅图书馆存储和处理的数据。该数据库是通过修改微软的Pubs数据库而设计的。 Pubs数据库提供了一组有关图书出版商、作者、书名和销售情况的虚构信息。现在它被认为已经过时了；自2008 版本以来， SQL Server不再提供它。表和字段非常明显。它们有Authors 、 Titles等名称，反映了它们的内容。这些字段也有明显的名称来解释它们所包含的内容。
您可以在链接中找到有关原始 Pubs DB 的详细信息：Microsoft Pubs DB
下面你可以看到Pubs数据库修改后的数据库图

END [dbo].[USP_InsertBook]存储过程有点复杂，因为它不仅仅创建一本书。如果没有与该新书关联的出版商或作者，它也可以帮助用户创建它们。这就是为什么[dbo].[USP_InsertBook]存储过程的@pub_id和@author_id参数是可选的。如果用户从前端应用程序的下拉菜单元素中选择现有发布者或作者，则所选选项的选定值（采用@pub_id或@author_id形式）将传递到存储过程。如果在下拉菜单（或数据库）中找不到新书的作者或出版商，应用程序可以轻松创建它们。使用下拉菜单上的最后一个选项Create New Author...和Create New Publisher... ，用户可以创建新作者或出版商。另外，一本书可能有前传，也可能没有。考虑到所有这些，创建一本书有 4 种可能的场景。
注意：下拉菜单项填充了数据库中现有的作者和出版商。

图书馆向希望从图书馆借书的人发放借书卡。图书馆通过存储card id 、 borrower name 、 address 、 phone number 、 birthdate 、 date the card was issued和balance due来保存每个借款人的列表。卡的有效期为自发行之日起十年。如果借款人未满 18 岁，图书馆还将保留借款人父母或法定监护人的信息，例如name 、 address和phone number 。一个人在特定时间只能拥有一张有效的图书卡。如果一个人在过期的借书卡上欠钱，则不能获得新的借书卡。
