某工厂仓库有一名保管员，该仓库可存放n箱零件。该工厂生产车间有m名工人，只要仓库空闲，工人将生产好的整箱零件放入仓库，并由保管员登记入库数量。该工厂销售部有k名销售员，只要仓库库存数能满足客户要求，便可提货，并由保管员登记出库数量。规定工人和销售员不能同时进入仓库，但是工人和工人，销售员和销售员可以同时进入仓库，其工作流程如图1-1所示。

 为了利用PV操作正确地协调工人和销售员进程之间的工作，设置了信号量S1、S2和S3，它们的初值分别为n、0和1。图1-1中的a、b、e和f应分别填写(25)；图1-1中的c、d、g和h应分别填写(26)。

The Rational Unified Process (RUP) is a software engineering process, which captures many of best practices in modern software development. The notions of use-cases and (71) have been proven to be an excellent way to capture function requirements. RUP can be described in two dimensions-time and content. In the time dimension, the software lifecycle is broken into cycles. Each cycle is divided into four consecutive (72) which is concluded with a well-defined (73) and can be further broken down into (74) - a complete development loop resulting in a release of an executable product, a subset of the final product under development, which grows incrementally to become the final system. The content structure refers to the disciplines, which group (75) logically by nature.

设关系模式R＜U,F＞，其中U{H,I,J,K,L}，若F={H→IJ,J→K,IJK→L,L→H,L→K)，则F的最小函数依赖集Fmin={(54)}，关系模式R的候选关键字是(55)。

设有职工实体Employee(职工号，姓名，性别，年龄，通信地址，家庭成员)，其中通信地址记录了邮编、省、市和街道信息；家庭成员记录了职工亲属的姓名。

 职工实体中的通信地址是一个(51)属性；为了将数据库模式设计的更合理，对于家庭成员属性(52)。
