【说明】

已知某唱片播放器不仅可以播放唱片,而且可以连接电脑并把电脑中的歌曲刻录到唱片上(同步歌曲)。连接电脑的过程中还可自动完成充电。

关于唱片,还有以下描述信息:

1.每首歌曲的描述信息包括:歌曲的名字、谱写这首歌曲的艺术家以及演奏这首歌曲的艺术家。只有两首歌曲的这三部分信息完全相同时,才认为它们是同一首歌曲。艺术家可能是一名歌手或一支由2名或2名以上的歌手所组成的乐队。一名歌手可以不属于任何乐队,也可以属于一个或多个乐队。 

2.每张唱片由多条音轨构成;一条音轨中只包含一首歌曲或为空,一首歌曲可分布在多条音轨上;同一首歌曲在一张唱片中最多只能出现一次。 

3.每条音轨都有一个开始位置和持续时间。一张唱片上音轨的次序是非常重要的,因此对于任意一条音轨,播放器需要准确地知道,它的下一条音轨和上——条音轨是什么(如果存在的话)。 

根据上述描述,采用面向对象方法对其进行分析与设计,得到了如表3-1所示的类列表、如图3-1所示的初始类图以及如图3-2所示的描述播放器行为的UML状态图。

根据说明中的描述,给山图3-1中(1)~(6)处的多重度。

题型:问答题

KK is a large listed company. When a non-executive directorship of KK Limited became available, John Soria was nominated to fi ll the vacancy. John is the brother-in-law of KK’s chief executive Ken Kava. John is also the CEO of Soria Supplies Ltd, KK’s largest single supplier and is, therefore, very familiar with KK and its industry. He has sold goods to KK for over 20 years and is on friendly terms with all of the senior offi cers in the company. In fact last year, Soria Supplies appointed KK’s fi nance director, Susan Schwab, to a non-executive directorship on its board. The executive directors of KK all know and like John and so plan to ask the nominations committee to appoint him before the next AGM. KK has recently undergone a period of rapid growth and has recently entered several new overseas markets, some of which, according to the fi nance director, are riskier than the domestic market. Ken Kava, being the dominant person on the KK board, has increased the risk exposure of the company according to some investors. They say that because most of the executive directors are less experienced, they rarely question his overseas expansion strategy. This expansion has also created a growth in employee numbers and an increase in the number of executive directors, mainly to manage the increasingly complex operations of the company. It was thought by some that the company lacked experience and knowledge of international markets as it expanded and that this increased the risk of the strategy’s failure. Some shareholders believed that the aggressive strategy, led by Ken Kava, has been careless as it has exposed KK Limited to some losses on overseas direct investments made before all necessary information on the investment was obtained. As a large listed company, the governance of KK is important to its shareholders. Fin Brun is one of KK’s largest shareholders and holds a large portfolio of shares including 8% of the shares in KK. At the last AGM he complained to KK’s chief executive, Ken Kava, that he needed more information on directors’ performance. Fin said that he didn’t know how to vote on board reappointments because he had no information on how they had performed in their jobs. Mr Kava said that the board intended to include a corporate governance section in future annual reports to address this and to provide other information that shareholders had asked for. He added, however, that he would not be able to publish information on the performance of individual executive directors as this was too complicated and actually not the concern of shareholders. It was, he said, the performance of the board as a whole that was important and he (Mr Kava) would manage the performance targets of individual directors. Required:

(a) Explain the term ‘confl ict of interest’ in the context of non-executive directors and discuss the potential confl icts of interest relating to KK and Soria Supplies if John Soria were to become a non-executive director of KK Limited. (8 marks)
