This document provides an overview of architectural modeling techniques in software engineering, including component diagrams, deployment diagrams, and collaboration diagrams. It describes the key elements and purposes of each type of diagram. Component diagrams show the organization and dependencies among software components, while deployment diagrams model the physical deployment of artifacts across nodes. Collaboration diagrams emphasize the structural relationships between objects that send and receive messages during interactions.
The objective is to explain how a software design may be represented as a set of interacting objects that manage their own state and operations and to introduce various models that describe an object-oriented design.
The Unified Modeling Language (UML) is a general-
purpose, developmental, modeling language in the field
of software engineering, that is intended to provide a
standard way to visualize the design of a system.
This Presentation contains all the topics in design concept of software engineering. This is much more helpful in designing new product. You have to consider some of the design concepts that are given in the ppt

3. Architectural Modeling
An architecture is the set of significant decisions about the
organization of a software system.
Guides about the elements, their interfaces their
collaborations and their composition.
Architecture can be defined at both a logical and
physical level.
Logical Architecture: It shows more generic view of the
architecture.
Physical Architecture: Describes in more details how the
software and systems are designed.
4. Component Diagram
Component diagrams are one of the two kinds of diagrams found
in modeling the physical aspects of object-oriented systems.
It shows organizations & dependencies among set of components.
It describe the organization of physical s/w components,
including source code, run time code & executable.
Addresses static implementation view of a system .it represents
the high-level parts that make up the system.
High level reusable parts of a system are represented in it.
Visualize the static aspect of the physical components and their
relationships and to specify their details for construction.
Collecting various executable, libraries, files, tables (physical
things)

6. Components : Components are made up of one or more
classes & describe parts of an application that can be
assembled and reused.
Defined as a physical replaceable part that conforms to and
provides the realization of a set of interfaces.
Graphically ,a component is rendered as a rectangle with
tabs, with the name of the object in it, preceded by a colon
and underlined.

7. • Interface : It is a collection of operations that are used to
specify a service of class or components.
• Graphically it is displayed as a circle or as a typical class
with stereotype of <<interface>>
• Types of interface
• Provided Interface
• An interface that the component provides as a service to
other component.
• Required Interface
• An interface that the component conforms to when
requesting services from other components.
<<interface>>
Component Diagram
8. • Relationships between component & its interface : A
provided interface is shown as a circle attached to the
component by a line and a “lollipop”.
• A required interface is shown as a semicircle attached to the
component by a line and a “socket”. In both cases, the name
of the interface is placed next to the symbol.

using a full realization relationship.

through the interface is connected to the interface using a dependency
relationship.

10. • Ports :Ports are used to control the implementation of all the
operations in all of the provided interfaces in the component.
• It is an explicit window into an encapsulatedcomponent.
• All of the interactions into and out of the component pass
through ports. It has identity.
• Component can communicate with the component througha
specific port.
• It is shown as a small square straddling the border of a
component. Both provided and required interfaces may be
attached to the port symbol.
• A provided interface represents a service that can be requested
through that port. A required interface represents a service that
the port needs to obtain from some other component.
Component Diagram
12. • Connectors : A wire between two port is calledconnector.
• It represent a link or a transient link. Instance of an ordinary
• association.
• A transient link represents a usage relationship between
two components.
• If two components are explicitly wired together, either directly
or through ports, just draw a line between them or their ports.
• If two components are connected because they have compatible
interface, you can use a ball-and-socket notation to show that
there is no inherent relationship between the components,
although they are connected inside this component.
• Types of Connector
• Direct connector Delegation connector

16. Deployment Diagram
Used to model the static deployment view of a system.
It is important for visualizing , specifying, and documenting
embedded, client/server, & distributed systems.
It is a diagram that shows the configuration of run time
processing nodes & the artifacts that live on them.
Graphically, a deployment diagram is a collection of vertices and
arcs.
Purpose of deployment Diagrams:
Visualize hardware topology of a system
Describe the H/W components used to deploy software components.
Describe runtime processing nodes.

19. • Node: Just like artifacts, are an important building block in
modeling the physical aspects of a system
• It is a physical elements that exists at run time & represents a
computational resource.
• Graphical representation of node is cube.
• Types of node
• Processor
• It is a piece of hardware capable of executing programs
• A Processor can have list of processes on it.
• Represented as shaded cube with name of the object.
• Device
• A device is apiece of hardware incapable of executing program.
• Device will also have on a cube.

30. Collaboration Diagram
A collaboration diagram is an interaction diagram that
emphasizes the structural organization of the objects that
send and receive messages.
It is used to represent more-complex flows, involving
iterations & branching.
Sequence diagrams and collaboration diagrams are
semantically equivalent that means conversion to the other
is possible without any loss of information.
Graphically it is a collection of vertices and arcs.
31. Following are the components of a Collaboration diagram:
Objects: The representation of an object is done by an object
symbol with its name and class underlined, separated by a colon.
Actors: Each actor has its respective role and name. In this, one
actor initiates the use case.
Links: The link is an instance of association, which associates the
objects and actors.
Link portrays a relationship between the objects through which
the messages are sent. It is represented by a solid line.
The link helps an object to connect with or navigate to another
object, such that the message flows are attached to links.
Messages: It is a communication between objects which carries
information.
32. Collaboration diagrams have two features that distinguish
them from sequence diagrams.
First, there is the path to indicate how one object is linked
to another, attach a path stereotype to the far end of a link
such as local, parameter, global, and self.
Second, there is the sequence number to indicate the time
order of a message denoted by prefixing the message with
a number, nesting is indicated by Dewey decimal
numbering (e.g.:- 1 is the first message; 1.1 is the nested in
message 1.) used for the given example .
