共享数据库是一种重要的企业应用集成方式。以下关于共享数据库集成方式的叙述中，错误的是 （20） 。

A．共享数据库集成方式通常将应用程序的数据存储在一个共享数据库中，通过制定统一的数据库模式来处理不同应用的集成需求

B．共享数据库为不同的应用程序提供了统一的数据存储与格式定义，能够解决不同应用程序中数据语义不一致的问题

C．多个应用程序可能通过共享数据库频繁地读取和修改相同的数据，这会使共享数据库成为一个性能瓶颈

D．共享数据库集成方式的一个重要限制来自外部的已封装应用，这些封装好的应用程序只能采用自己定义的数据库模式，调整和集成余地较小

     The tower of Big Ben, London's most famous building, has always leaned (倾斜) slightly, but

construction work on a new line for the London Underground seemed likely to give the tower a

real lean. Engineers have had to prop up (支撑) its base to prevent it from damaging the rest of the

Houses of Parliament.

     To control the tower's movement,engineers pumped grout (水泥浆) into the soil under the tower.

The tower not leans an extra few centimeters, but the lean can only be seen by the most sharp-eyed

observer.

     Between 1995 and 1997, to lengthen the Jubilee line of the Underground, builders dug a

40-metre-deep hole just 31 metres north of the clock tower. And the new tube (underground ) tunnels

were even nearer to the tower. John Burland, who recently helped stop the increasing lean in the

Leaning Tower of Pisa and was an adviser to the Jubilee line project, believed the work would affect

the tower. In his opinion,no further lean should go beyond a safety limit of 27.5 millimetres over the

existing lean of 220 millimetres.

     To keep the lean within this limit,Burland told the British Association about the new method of

pumping grout immediately unde the base of the tower.More than 300 tons of grout were pumped

in during construction.The tower's additional lean went between 10 and 25 millimetres,but never

passed 27.5 millimetres.

      After the construction work was completed in last 1997, a review of movements in nearby walls

showed that the building was in better shape than had been thought before and the safety limit was

raised to 35 millimetres before any action needs to be taken.

     Since 1997,the tower had continued to lean, Burland told Modern Constuction.The latest

measurements,taken this year,suggest that the tower's lean had just reached 35 millimetres.But

following regular re-examinations of the tower,experts are sure that the tower has stabilised(稳定).

A spokesman for London Underground says: "We understand the tower has stabilised and retuned to

its normal movement cycle."
