高级终端用户在数据规划过程中起着 【17】

答案

参考答案:辅助作用

解析: 高级终端用户在数据规划过程中起着辅助作用。 相关知识点: 一般每个活动都与多个实体有关。高级终端用户在数据规划过程中起着辅助作用,他们应画出所管辖范围内的功能活动图,相互对照所使用的实体,如果对于一个功能需要哪些实体还不清楚,那么说明功能分解进行还欠彻底。 实体图和功能分解两者可能都不完全,随着时间的推移,应该修改和补充,开始的时候希望得到一个全局概况,因而比较粗糙。随后,详细的数据模型化和计算机过程设计都要花费很长的时间,再进行仔细工作后,就可以更新功能分解图、实体图以及它们相互参照的数据库。

     Acting is such an over-crowded profession that the only advice that should be given to a

young person thinking of going on the stage is "Don't!". But it is useless to try to discourage

someone who feels that he must act, though the chances of his becoming famous are slim. The

normal way to begin is too to a drama school. Usually only students who show promise and

talent are accepted, and the course lasts two years.

Then the young actor or actress takes up work with a repertory company, usually as an assistant

stage manager. This means doing everything that there is to do in the theatre: painting scenery,

looking after the furniture, taking care of the costumes, and even acting in very small parts. It is

very hard work indeed. The hours are long and the salary is tiny. But young actors with the stage

in their blood are happy, waiting for the chances of working with a better company, or perhaps

in films or television.

     Of course, some people have unusual chances which lead to fame and success without this

long and dull training. Connie Pratt, for example, was just an ordinary girl working in a bicycle

factory. A film producer happened to catch sight of her one morning waiting at a bus stop, as he

drove past in his big car. He told the driver to stop, and he got out to speak to the girl. He asked

her if she would like to go to the film studio

to do a test, and at first she thought he was joking. Then she got angry and said she would call the

police. It took the producer twenty minutes to tell Connie that he was serious. Then an appointment

was made for her to go to the studio the next day. The test was successful. They gave her some

necessary lessons and within a few weeks she was playing the leading part opposite one of the

most famous actors of the day. Of

course, she was given a more dramatic name, which is now world-famous. But chances like this

happen once in a blue moon!
