Integration framework for CASE tool.

A integration framework for CASE (computer-aided software engineering)
environments identifies five sets of services that such an environment should
provide

The five levels of service in integration framework are:

· Data repository services These provide facilities for the storage and
management of data items and their relationships.

· Data integration services These provide facilities for managing groups or
the establishment of relationships between them. These services and data
repository services are the basis of data integration in the environment.

· Task management services These provide facilities for the definition and
enactment of process models. They support process integration.

· Message services These provide facilities for tool-tool, environment-tool and
environment-environment communications. They support control integration.

· User interface services These provide facilities for user interface

development. They support presentation integration.

Artificial Intelligence 1.    What is AI technique? Artificial  Intelligence (AI)  is  the study  of  how  to make computers do things which, at  the moment, people do better. It is a method that exploits knowledge that should be represented in such a way that: ·    The knowledge captures generalizations. ·    It can be understood by people who must provide it. ·    It can be easily modified to correct errors and to reflect changes. ·    It can be used in situations even if it is not accurate and complete. ·    It helps to narrow the range of possibilities that is has to be considered. 2.    What are the steps to be considered to solve a problem? To solve a particular problem, the following steps are taken into account, ·    Define the problem precisely. ·    Analyze the problem. ·    Isolate and represent the task knowledge that is necessary to solve a problem. ·    Choose the best problem-solving techniques and apply it to a particular problem.

The taxonomy of CASE Tools

CASE Tool Taxonomy CASE tools can be classified by · by function, · by user type (e.g. manager, tester), or · by stage in SE process (e.g. requirements, test) The following taxonomy is classified by function. Business Information Tools model business information flow. The tools represent business data object and model their flow. Network tools could be modified to yield the same functionality. Process Management Tools model processes. You have to understand the process in order to model it. The tools help you capture process. This is a key component of TQI. Project Planning Tools help plan and schedule projects. Examples are PERT and CPM. Finding parallelismand eliminating bottlenecks assist in streamlining projects. Risk Analysis Tools helps build a risk table from the schedule outlining the risk each component of the production process and categorizing the risks as catastrophic, critical, marginal, or negligible. A cost is associated with eac

Zoho Second round - adding a digit to all the digits of a number

Adding a digit to all the digits of a number eg digit=4, number = 2875, o/p= 612119 C Program: #include<stdio.h> #include<conio.h> #include<string.h> int main() {     int t,n,i=0;     char num[100];     printf("Enter the digit: ");     scanf("%d",&n);     printf("Enter the number: ");     scanf("%s",num);     printf("o/p ");     for(i=0;i<strlen(num);i++)     {     printf("%d",num[i]-'0'+n);     }  getch();  return 0; }
