在图书馆管理系统中，要为每个借阅者建立一个账户，并给借阅者发放借阅卡（借阅卡可以提供借阅卡号、借阅者姓名），账户中存储借阅的个人信息、借阅信息以及预定信息。持有借阅卡的借阅者可以借阅书刊、返还书刊、查阅书刊信息、预定书刊并取消预定，但这些操作都是通过图书馆管理员进行的，也及借阅者不直接与系统交互，而是图书馆管理员充当借阅者的代理与系统交互。在借阅书刊时，需要输入所借阅的书刊名，书刊的ISBN/ISSN号，然后输入借阅者的图书卡号和借阅者名，完成后提交表格，系统验证借阅者是否有效（在系统中存在账户），若有效，借阅请求被接受，然后查询数据库系统，看借阅者所借阅的书刊是否存在，若存在，则借阅者可以借出书刊，建立并在系统中存储借阅纪录。借阅者还书后，删除关于所还书刊的借阅纪录。如果借阅者所借出的书刊已经被借出，借阅者还可预订该书刊，一旦借阅者预订的书刊可以获得，就将书刊直接寄给预订人（为了简化系统，预订书刊可获得就不通知借阅者了）。另外，系统设置了书刊的最长借阅期，如果借阅者归还的时间超过了最长借阅期，要缴纳一定的滞纳金。- Readers card holders can borrow books, return books, check books information, books and planned to cancel, but these operations are carried out by the librarians, and do not borrow directly with the interactive system, but librarians who act as agents to borrow and system interaction. The books, by the need to import borrow books, and books by ISBN/ISSN, and then borrow the book numbers and those who borrow, forms submitted after completion, the system certification Readers whether effective (in the system exist account), if eff

　Linux拥有丰富各种源代码资源,但是大部分代码在Windows平台情况是无法正常编译的。Windows平台根本无法直接利用这些源代码资源。如果想要使用完整的代码，就要做移植工作。-rich variety of Linux source code resources, But most of the code in the Windows platform is not the normal compiler. Windows platform can not directly use these resources to the source code. If you want to use the code integrity, we should do transplants.
