Question

急急！！请帮忙翻译成中文！！！谢谢！！！！

The basic security requirements of databasesystems are not unlike those of other computing systems we have studied. Thebasic problems access control, exclusion of spurious data, authentication ofusers, and reliability have appeared inmany contexts so far in this book, Following is a list of requirements fordatabase security.

Physical database integrity, The data of adatabase are immune to physical problems, such as power failures, and someonecan reconstruct the database if it is destroyed thorough a catastrophe.

Logical database integrity, The structureof the database is preserved. With logical integrity of a database, a modificationto the value of one field does not affect other fields, for example.

Element integrity, The data contained ineach element are accurate.

Auditability. It is possible to track who or what has accessed(or modified) the elements in thedatabase.

Access control,. A user is allowed toaccess only authorized data, and different users can be restricted to differentmodes of access (such as read or write).

User authentication, Every user ispositively identified, both for the audit trail and for permission to accesscertain data.

Availability. Users can access the databasein general and all the data for which they are authorized

这么长的一段，你也好意思！
在本书的各种上下文中已经讨论了各种（安全相关的）基本问题，包括：访问控制、木马数据、用户鉴权以及可靠性。数据库系统的安全需求与我们已知的其它计算机系统都不同。下表是数据库安全的需求：
物理数据库一致性。数据库中的数据必须能够承受物理故障，比如：电源失效，管理员可以在灾后重建数据库。
逻辑数据库一致性。数据库的结构是受保护的，对一个数据的修改不会影响其它数据，比如：成员一致性，每个成员中保存的数据都是正确的。
可审计。可以追踪是谁或者什么访问了数据库中的成员数据。
访问控制。用户只能访问被授权的数据，不同用户的访问权限可能不同，比如：读、写
用户认证。用户访问数据前必须通过身份认证，保证访问操作可审计，并控制访问数据范围和权限
可用性。用户总是可以访问被授权的所有数据
