Important Points to Note

• All Participating colleges are requested to mute your audio lines during the webinar session.

• Participants are requested to make note of questions / responses to questions, if any, and pass them onto the Class Representative who can sit closer to the system to send out the messages on behalf of theclass.

• Question & Answer(Q&A) is scheduled at the end of the session and each college is given a chance toask 2-3 questions. Answers to the questions posted by colleges through chat option will also beanswered during the Q&A.

• Instructor may initiate relevant Polls at regular intervals during the session. Institutes are requested togain inputs from all the participants and provide your responses to these polls initiated by instructor.

• Session Feedback will be initiated at the end of the webinar. Institutes are requested to get thecollective opinion from the participants and provide your responses for the feedback questionnaire.

Recap: Introduction to InceptionIncepting an enterprise application is the first life cycle phase of raising enterprise applications that primarily consists of the following activities:

• Enterprise analysis

• Business modeling

• Requirements elicitation & analysis

• Requirements validation

• Planning and estimation

5

Requirement Elicitation and Analysis• Requirements elicitation and analysis is a systematic approach

of capturing client requirements, analyzing them and documenting the problem domain.

• There are various kinds of requirements which need to be elicited and are broadly divided into two categories:– Functional Requirements– Non Functional Requirements(NFR)

• Functional requirement elicitation and analysis starts with – enlisting the entities that use the system => Actors– the functional reasons why they will use the system => Use Cases

via internet / bank representative to be considered as customer

9. Approved loan amount is disbursed to customer

7. Verifier verify the documents and send for approval

3. Customer provides information via internet or bank representative

5. Customer submit loan application for pre-approved loan amount (or less) or opt for higher amount6. Customer uploads necessary

documents or hands it over to bank representative for verification

8. Approver approves the loan

Why does an actor need to interact with the system?

Initiates loan

Generate Preapproved loan amount based on customer’s credit rating

Upload documents

Verifies uploaded documents

Approves the loan

Loan disbursed

Register with the bank

Unified Modelling Language• Visual language of modelling business processes and software systems• Behavior diagram – what must happen in system being modelled

– Use case diagram – to represent functional requirements view– Activity diagram – describes business and operational step by step workflows of

components in a system

• Interaction diagram – flow of control and data in the system– Sequence diagram – depicts how objects communicate with each other in a

sequence of messages and indicates lifespan of objects

• Structure diagram – highlight what must be present in modelled system– Class diagram – describes structure of system– Deployment diagram - describes the hardware used in system implementations and

the execution environments and artifacts deployed on the hardware.

Use Case Diagram

• Identify actors

• Identify use cases

• Identify relationship between actor and use case

– Association

• Simplest relationship

• Represented by straight line
