Synchronous Messages

Nested flow of control, typically implemented as an operation call.

The routine that handles the message is completed before the caller

resumes execution.

:A :B

doYouUnderstand()

Caller Blocked

return (optional)yes

Asynchronous

In this type of message the flow is not interrupted and response is not

awaited.

An asynchronous message is drawn with a half-arrowhead, that

(one with only one wing instead of two) as shown below

Combined Fragment

Combined fragment is an interaction fragment which defines a

combination (expression) of interaction fragments.

A combined fragment is defined by an interaction operator and

corresponding interaction operands

For every option there will be corresponding action11

Scenario

i. The user will submit the cheque for withdraw.

ii. Bank will check the amount of cheque to be withdrawn.

iii. Bank will check the amount available in the account.

iv. If balance >amount to be withdrawn then debit transaction is

performed and photo of cheque is stored

v. Otherwise the cheque will be returned with message of insufficient

fund.

Deployment Diagram

Deployment diagrams are used for describing

the hardware components where software

components are deployed

Deployment diagrams are used to describe

the static deployment view of a system14

Purpose of the Diagram The purpose of deployment diagrams can be

described as:

i. Visualize hardware topology of a system.

ii. Describe the hardware components used to

deploy software components.

iii. Describe runtime processing nodes.

15

Target Audience

Deployment diagrams are useful for system engineers.

An efficient deployment diagram is very important

because it controls the following parameters

i. Performance

ii. Scalability

iii. Maintainability

iv. Portability

16

Artifacts in Deployment Diagram

Nodes:

Nodes are nothing but physical hardwares used

to deploy the application.

Deployment diagrams consist of nodes and their

relationships.17

Sample Scenario

The following deployment diagram is a sample togive an idea of the deployment view of ordermanagement system.

Monitor

Modem

Caching server

Server

18

Application Flow• The application is assumed to be a web based

application which is deployed in a clustered

environment using server 1, server 2 and server

3. The user is connecting to the application using

internet. The control is flowing from the caching

server to the clustered environment.
