UML Modeling And Programming With EMF

In this report we will discuss about UML & EMF and below are the summaries point:- The main stakeholders to be considered in designing the system are the manager, client, and consultant. The business entities to be served are sole proprietor ship, corporation, and small business corporation. Use cases for the system include login, register, request submit, approve request, and more. The system will provide IT solutions to customers who submit requests through the company's website. Consultants will be assigned to requests one at a time, and customers can request a different consultant if they are not satisfied with the outcome. Customers must have an account with a login ID and password to submit a request. The request status field can store progressing, de-satisfied, completed, and rejected status. Payment can be made either by cash or card. The system will only accept requests from registered customers, and each consultant will be assigned to one request at a time. Each customer can have one active request, and all users must be registered in the system. A plugin project named itSolution.instance was created with dependencies including org.eclipse.emf.ecore, org.eclipse.emf.ecore.xmi, and itSolution.

Task 1: System Description:
The main stakeholders to be considered while designing the system are manager, client
and consultant. The business entities are sole proprietorship, corporation and small business
corporation. The use cases are login, register, request submit, approve request and many more.
The activities of the business are listed below.
i. The IT Solution provides various IT related solutions to customers
ii. The customer has to submit a request first through their website
iii. The IT Solution will assign consultant one at a time to the request
iv. If the outcome is not satisfactory, the customer can request for another consultant
v. The customer needs to have an account to submit a request
vi. Each customer has a login id and password
vii. The request will have a status field which can store progressing, de-satisfied,
completed and rejected status
viii. The customer can pay the charge either by cash or card

3.b Business Constraints:
The business constraints are as following.
i. The organization will accept request of only registered customers
ii. One consultant will be assigned to one request
iii. A customer can have one active request
iv. Every user have to be registered into the system
Business Constraint OCL
One consultant will
be assigned to one
request
context Request inv: consultant->size() <= 1;
A customer can have
one active request
context Client inv: self.request->size()=1;

Task 4: Model Instance
Created a plugin project with name itSolution.instance.
Then the following dependencies are added to plugin.xml. org.eclipse.emf.ecore,
org.eclipse.emf.ecore.xmi and itSolution.
The class for creating the instance is as following.
package de.vogella.emf.webpage.instance;
import java.io.IOException;
import java.util.Collections;
import java.util.Map;
