问题 问答题

[说明]

某房屋租赁公司欲建立一个房屋租赁服务系统,统一管理房主和租赁者的信息,从而快速地提供租赁服务。该系统具有以下功能:

1.登记房主信息。对于每名房主,系统需登记其姓名、住址和联系电话,并将这些信息写入房主信息文件。

2.登记房屋信息。所有在系统中登记的房屋都有一个唯一的识别号(对于新增加的房屋,系统会自动为其分配一个识别号)。除此之外,还需登记该房屋的地址、房型(如平房、带阳台的楼房、独立式住宅等)、最多能够容纳的房客数、租金及房屋状况(待租赁、已出租)。这些信息都保存在房屋信息文件中。一名房主可以在系统中登记多个待租赁的房屋。

3.登记租赁者信息。所有想通过该系统租赁房屋的租赁者,必须首先在系统中登记个人信息,包括:姓名、住址、电话号码、出生年月和性别。这些信息都保存在租赁者信息文件中。

4.租赁房屋。已经登记在系统中的租赁者,可以得到一份系统提供的待租赁房屋列表。一旦租赁者从中找到合适的房屋,就可以提出看房请求。系统会安排租赁者与房主见面。对于每次看房,系统会生成一条看房记录并将其写入看房记录文件中。

5.收取手续费。房主登记完房屋后,系统会生成一份费用单,房主根据费用单缴纳相应的费用。 :

6.变更房屋状态。当租赁者与房主达成租房或退房协议后,房主向系统提交变更房屋状态的请求。系统将根据房主的请求,修改房屋信息文件。

数据流图1-1和图1-2分别给出了该系统的顶层数据流图和0层数据流图。

使用[说明]中给出的词汇,将数据流图1-1中(1)~(4)处的数据流补充完整。

Directions: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.

Sociologists have long recognised that organisations of less than 200 individuals can operate through the free flow of information among the members. Once their size goes beyond this figure, the organizations are getting less flexible. So it seems necessary to prevent total disorder resulting from failures of communication.

One solution to this problem would, of course, be to structure large organisations into smaller units of a size that can act as a group. By allowing these groups to build reliance on each other, larger organizations can be built up. However, merely having groups of, say, 150 will never of itself be a complete solution to the problems of the organization. Something else is needed: the people involved must be able to build direct personal relationships. To allow free flow of information, they have to be able to communicate with each other in a casual way. Maintaining too formal a structure of relationships inevitably prevents the way a system works.

The importance of this was drawn to my attention two years ago by the case of a TV station. Whether by chance or by design, it so happened that there were almost exactly 150 people in the station. The whole process worked very smoothly as an organization for many years until they were moved into purpose-built accommodation. Then, for no apparent reason, the work seemed to be more difficult to do, not to say less satisfying.

It was some time before they work out what the problem was. It turn out that, when the architects were designing the new building, they decided that the coffee room where everyone ate their sandwiches at lunch times was an unnecessary luxury and so did away with it. And with that, they accidentally destroyed the close social networks that strengthened the whole organization. What had apparently been happening was that, as people gathered informally over their sandwiches in the coffee room, useful information was casually being exchanged.

(Note: Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS.)

小题1:What size of an organization may lead to communication failures?

小题2:What are the two solutions to the communication problem within a large organization?

小题3:After the TV station moved into new accommodation, its operation ___________________________.

小题4:From the case of the TV station, we can conclude it is ____________________________________ that make(s) an organization more successful.
