Software entities are more complex for
their size than perhaps any other human construct, because no two parts are
alike (at least above the statement level). If they are, we make the two
similar parts into one, a(71 ), open or closed. In this respect software systems differ
profoundly from computers,buildings, or automobiles, where repeated elements
abound.
Digital computers are themselves more
complex than most things people build; they have very large numbers of states.
This makes conceiving, describing, and testing them hard. Software systems have
orders of magnitude more (72 )than computers do.
Likewise, a scaling-up of a software entity
is not merely a repetition of the same elements in larger size; it is necessarily an increase in
the number of different elements. In most cases, the elements interact with
each other in some( 73 )fashion,and
the complexity of the whole increases much more than linearly.
The complexity of software is a(an)(74 )property, not
an accidental one. Hence descriptions of a software entity that abstract away
its complexity often abstract away its essence.Mathematics and the physical
sciences made great strides for three centuries by constructing simplified
models of complex phenomena, deriving properties from the models, and verifying
those properties experimentally. This worked because the complexities(75 )in the models
were not the essential properties of the phenomena. It does not work when the
complexities are the essence.
Many of the classical problems of
developing software products derive from this essential complexity and its nonlinear increases with
size. Not only technical problems but management problems as well come from the complexity.
【说明】利用ASP+access开发网站管理系统,设计以下两个网页Add_form.asp 和Add.asp,通过它们将网站信息添加到数据库test.mdb 中website表中。下图是Add_form.asp 浏览页面,在其上输入需要添加页面内容后,单击"确定"按钮,执行Add.asp 页面完成相应内容添加到数据库test.mdb 中。
问题1:完成程序中空白处填空。
<% Option Eplicit%><Html><head><title>添加记录示例</title></head>(1)align="center">添加新网站</h2><center><table border="1" width="90%"><form name ="form1"method="(2)"action=(3)"><tr><td>网站名称</td><td><input type="(4)"name="name" size=20></td></tr><tr><td>网站地址</td><td><input type="text"name="URL" size=40></td></tr><tr><td>网站简介</td><td>(5) name ="into" row="2"cols="40"wrap="solf "></textarea></td></tr><tr><td> </td><td><input type=(6)" "value="确定"><input type=(7)" "value="(8)"</td></tr></from></table></center></body></html>
添加数据记录执行程序add.asp:
<% Otion Eplicit><% '如果上面信息已经填全了,就添加记录,否则给出错误提示信息Dim connSet conn=server.(9)("ADODB.Connection")conn.Open "Dbq="&Server,mappath("(10)")&";Driver={Microsoft Access Driver(*.mdb)};"Dim strSql,varName,varURL,varlntro,rs '定义变量VarName=Request.Form("(11)")VarURL=Request.Form(" URL")VarIntro =Request.Form("Intro")(12)="Insert into website (name,URL.intro,submit_date)Values( "&varName &","&_varURL&","& varIntro &",# "&Date( )&" # )" 'Date( )表示取服务器时间Set rs=conn.(13) (strSql)index.asp" '添加成功,则返回首页index.asp…response.(14) "请将所有信息填写完整"response.
