● Management information systems form. a bedrock of IT use in the public sector. They are therefore found in all sections ofthe public sector and in all countries..Of course, different people use the term "management information system" differently. The term should therefore not form. the basis for arguments about (71) an MIS is and is not. So long as one and those with whom one works understand and agree on a definition, that is good enough.Similarly, when dealing with written material, one needs to be able to(72)and communicate, not get locked into doctrinal debate,
Many public service providers have developed management information systems to morutor and control the services that they provide. Both the US (73) UK Social Security agencies have developed MIS to report on the welfare payments and services that they provide . The British public healthcare system has also been a major investor in MIS as it 1ries to control healthcare costs and simultaneously improve delivery standards .
Individual schools can also(74)use of MIS. Hobmoor Junior and Infant School, a public school in Birmingham, UK, introduced a computerised attendance system to produce MIS reports that monitor pupil attendance. This improved the Principal's ability to understand and control absence patterns, resulting in a 2.5 per cent ( 75) in attendance rates.

第1题：
下列程序的运行结果是______。 includeclass A { public: virtual void use( ) {cou 下列程序的运行结果是______。
include＜iostream.h＞
class A
{
public:
virtual void use( ) {cout＜＜"in A\n";}
};
class B:public A
{
public:
virtual void use( ) {cout＜＜"in B\n";}
};
class C:public B
{
public:
virtual void use( ){cout<<"in C\n";}
};
void main( )
{
A*obj；
bj=new C;
obj-＞use( );
delete obj;
}
正确答案：in C
in C 解析：本题考查虚函数和多态性。原本obj指向祖先类，随后被赋值，指向新的子孙类，则在使用use这个重载的虚函数时，根据当前指向可确定调用子孙的同名虚函数。 -
第2题：
在下列基类的定义中，有无virtual修饰use成员函数的结果将不同，其原因是______。
当use( )为虚拟函数时的程序执行结果：
sizeof(A)=8
sized(B)=12
sizeof(C)=16
当use( )非虚拟函数时的程序执行结果：
sizeof(A)=4
sized(B)=8
sizeof(C)=12
源程序如下：
include＜iostream.h＞
class Grandad
{
public:
Grandad( ):money(10){}
int money;
virtual void use( ){}
};
class Father:public Grandad
{
public:
Father( ):money(100){}
int money;
void use( ){}
};
class Son:public Father
{
public:
Son( ):money(300){}
int money;
void use( ){}
};
void main(void)
{
Grandad A;Father B;Son C;
cout＜＜"sizeof(A)="＜＜sizeof(A)＜＜endl;
cout＜＜"sizeof(B)="＜＜sizeof(B)＜＜endl;
cout＜＜"sizeof(C)="＜＜sizeof(C)＜＜endl;
}
正确答案：采用虚函数的每个派生类都含有一个指向虚函数表的指针故多4字节。

第4题：
有如下SQL SELECT语句SELECT*FORM. 工资表 WHERE 基本工资<=2000 AND 基本工资>=1500下列与该语有如下SQL SELECT语句 SELECT*FORM. 工资表 WHERE 基本工资＜＝2000 AND 基本工资＞＝1500 下列与该语句等价的
A．SELECT*FORM. 工资表 WHERE 基本工资 BETWEEN 1500 AND 2000
B．SELECT*FORM. 工资表 WHERE 基本工资 BETWEEN 2000 AND 1500
C．SELECT*FORM. 工资表 WHERE 基本工资 FROM1500 INTO 2000
D．SELECT*FORM. 工资表 WHERE 基本工资 FROM 2000 INTO 1500
正确答案：A
解析：SQL查询语句中特殊运算BE- TWEEN．．．AND．．，的含义为“…和…之间”。BETWEEN…AND．．．是SQL查询语句中的一个特殊运算符，意思为“…和…之间”，相当与逻辑运算中的(A＞＝AND＞＝8，其中A＞B)，选项 B)中数值放置错误，选项 -

A．SELECT * FORM. 成绩表 WHERE 物理＜=90 AND 物理 ＞=80
B．SELECT * FORM. 成绩表 WHERE 物理 ＜90 AND 物理＞80
C．SELECT * FORM. 成绩表 WHERE 物理＞=90 AND 物理＜=80
D．SELECT * FORM. 成绩表 WHERE 物理＞90 AND 物理＜80
正确答案：A
解析：BETWEEN..AND...是SQL查询语句中的一个特殊运算符，意思为“...和...之间”，相当与逻辑与运算中的(A＞=AND＞=B，其中A＞B)。 -
