The various feature of CASE repository

The Role of the Repository in I-CASE

The repository for an I-CASE environment is the set of mechanisms and data
structures that achieve data/tool and data/data integration. It provides the obvious
functions of a database management system, but in addition, the repository performs
or precipitates the following functions.

• Data integrity includes functions to validate entries to the repository, ensure
consistency among related objects, and automatically perform "cascading"
modifications when a change to one object demands some change to objects related
to it.

• Information sharing provides a mechanism for sharing information among multiple
developers and between multiple tools, manages and controls multiuser access to
data and locks or unlocks objects so that changes are not inadvertently overlaid on
one another.

• Data/tool integration establishes a data model that can be accessed by all tools in
the I-CASE environment, controls access to the data, and performs appropriate
configuration management functions.

• Data/data integration is the database management system that relates data
objects so that other functions can be achieved.

•Methodology enforcement defines an entity-relationship model stored in the
repository that implies a specific paradigm for software engineering; at a minimum,
the relationships and objects define a set of steps that must be conducted to build
the contents of the repository.

•Document standardization is the definition of objects in the database that leads

directly to a standard approach for the creation of software engineering documents.

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; }
