8.Unified Process Modelling.ppt of software enggSukhmanSingh91
The Unified Process (UP) is a framework for software development that uses iterative development. It breaks projects into short iterations of 2-6 weeks to develop executable subsets of the system. Each iteration includes requirements analysis, design, implementation, and testing. This allows for early feedback and risk mitigation. The UP also structures work into four phases - Inception focuses on feasibility, Elaboration builds the core architecture, Construction implements remaining elements, and Transition handles deployment. Iterations are time-boxed to keep projects on schedule.
The document discusses use case diagrams in UML modeling. It defines key components of use case diagrams including use cases, actors, the system boundary, and relationships like include, extend, and generalization. It provides examples of how to construct a use case diagram based on system functions and user goals. Specific use case diagram examples shown include an online ordering system and a vending machine.
UML was developed to standardize object-oriented modeling notations. It consolidated techniques like OMT, OOSE, and the Booch Methodology. UML provides multiple views (diagrams) to model a system, including structural, behavioral, implementation, and environmental views. Common UML diagrams are use case diagrams, which model functionality from the user's perspective, and class diagrams, which show system structure.
UML (Unified Modeling Language) is a standard modeling language used to document and visualize the design of object-oriented software systems. It was developed in the 1990s to standardize the different object-oriented modeling notations that existed. UML is based on several influential object-oriented analysis and design methodologies. It includes diagrams for modeling a system's structural and behavioral elements, and has continued to evolve with refinements and expanded applicability.

3. Unified Modeling Language (Contd.)
• A model is simplified because reality is too complex or
large and much of the complexity actually is irrelevant
to the problem we are trying to describe or solve
• A Model provides a means for conceptualization and
communication of ideas in a precise and unambiguous
form.
• The characteristics of simplification and representation
are difficult to achieve in the real world
• Most modeling technique used during many of the
phases of the SLC(service life cycle) such as analysis,
design and implementation
4. Unified Modeling Language (Contd.)
• For example, objectory is build around several different models:
– Use-case model
defines the outside(actor) and inside (use-case) of the system’s
behavior
– Domain object model
Objects of real world are mapped into the domain object model
– Analysis object model
The analysis object model presents how the source code should
be carried out and written
– Implementation Model
The implementation model represents the implementation of the
system
– Test model
The test model constitutes the test plans, specifications, and
5. Static and Dynamic Models
• Models can represent static and dynamic
• Each representation has different implications for how the
knowledge about the model might be organized and represented
• Static Model
– A static model can be viewed as a snapshot of a system’s parameters at
rest or a specific point in time.
– Static models are needed to represent the structural static aspect of a
system
– For example a customer could have more than one account or an order
could be aggregated from one or more line items.
– Static models assume stability and an absence of change in data over time
.
– The unified modeling language class diagram is an example of a static
model
6. Static and Dynamic Models (Contd.)
• Dynamic model
– In contrast to a static model, can be viewed as a
collection of procedures or behaviors that, taken
together, reflect the behavior of a system over time.
– Dynamic relationships show how the business
objects interacts to perform tasks.
– For example, an order interacts with inventory to
determine product availability.
– The UML interaction diagram and activity models
are examples of UML dynamic models
7. Why Modeling?
• Building a model for a software system prior to its
construction is as essential as having a blueprint
for building a large building.
• Good models are essential for communication
among project teams.
• A modeling language must include
– Model elements – fundamental modeling concepts
and semantics
– Notation – visual rendering of model elements
– Guidelines – expression of usage within the trade
8. Modeling (Contd.)
• The use of visual notation to represent or model a problem
can provide us several benefits relating to
– Clarity : we are much better at picking out errors and omissions
from a graphical or visual representation than from listing of
code or tables of numbers.
– Familiarity : The representation form for the model may turn
out to be similar to the way in which the information actually is
represented and used by the employee currently working in the
problem domain.
– Maintenance : visual notation can improve the maintainability
of a system.
– Simplification : Use of a higher level representation generally
results in the use of fewer but more general constructs,
contributing to simplicity and conceptual understanding
9. Advantages of Modeling
• Models make it easier to express complex
ideas
• Reduction of complexity
• Enhance and reinforce learning and training
• Cost is low
• Manipulation is much easier
10. Key Ideas of Modeling
• A model is rarely correct on the first try
• Always seek the advice and criticism of others.
You can improve a model by reconciling
different perspective
• Avoid excess model revision, as they can
distort the essence of your model.
11. Introduction to the UML
• The UML is a languague for specifying, constructing,
visualizing and documenting the software system and its
components.
• The UML is a graphical language with sets of rules and
semantic
• The rules and semantics of a model are expressed in
english, in a form known as object constraint
language(OCL).
• OCL is a specification language that uses simple logic for
specifying the properties of a system.
• The UML is not intended to be a visual programming
language in the sense of having all the necessary visual and
semantic support to replace programming languages.
12. Introduction to the UML (Contd.)
• The primary goal in the design of the UML were
– Provide users a ready –to-use, expressive visual modeling
language develop and exchange meaningful models
– Provide extensibility and specialization mechanisms to
extend the core concepts
– Be independent of particular programming languages and
development processes
– Provide a formal basis for understanding the modeling
language
– Encourage the growth of the OO tools market
– Support higher-level development concepts
– Integrate best practices and methodologies
13. UML Diagrams
• Every complex system is best approached through a small set of nearly
independent views of a model; no single view is sufficient.
• The UML defines nine graphical diagrams
– Class diagram(static)
– Use-case diagram
– Behavior diagram(Dynamic)
• Interaction diagram
– Sequence diagram
– Collaboration diagram
• Statechart diagram
• Activity diagram
– Implementation diagram
• Component diagram
• Deployment diagram
14. Use Case Diagram
• Used for describing a set of user scenarios
• Mainly used for capturing user requirements
• Work like a contract between end user and
software developers
15. Use Case Diagram (core components)
Actors: A role that a user plays with respect to the system,including
human users and other systems. e.g.,inanimate physical objects (e.g. robot);
an external system that needs some information from the current system.
Use case: A set of scenarios that describing an interaction between a user
and a system, including alternatives.
System boundary: rectangle diagram representing the boundary between
the actors and the system.
16. Use Case Diagram(core relationship)
Association: communication between an actor and
a use case; Represented by a solid line.
Generalization: relationship between one general
use case and a special use case (used for defining
special alternatives)
Represented by a line with a triangular arrow head
toward the parent use case.
17. Use Case Diagram(core relationship)
Extend: a dotted line labeled <<extend>> with an arrow
toward the base case. The extending use case may add behavior to
the base use case. The base class declares “extension points”.
<<extend>>
Include: a dotted line labeled <<include>> beginning at base
use case and ending with an arrows pointing to the include use
case. The include relationship occurs when a chunk of
behavior is similar across more than one use case. Use
“include” in stead of copying the description of that behavior.

[UseCase] -> [Package] button and click at the
location where package will be placed in the [main
window].
37. Class Diagram
• It is also referred to as object modeling, is the main
static analysis diagram.
• A class diagram is a collection of static modeling
elements, such as classes and their relationships,
connected as a graph to each other and to their
contents.
• For example the things that exist, their internal
structures, and their relationships to other classes.
• Class diagrams do not show temporal information,
which is required in dynamic modeling.
38. Class Diagram
• Object modeling is the process by which the logical
objects in the real world are represented by the
actual objects in the program.
• This visual representation of the objects, their
relationships, and their structures is for ease of
understanding.
• To effectively develop a model of the real world
and to determine the objects required in the
system, you first must ask what objects are needed
to model the system.
39. Class Diagram
• Answering the following questions will help you to stay
focused on the problem at hand and determine what is inside
the problem domain and what is outside it:
– What are the goals of the system?
– What must the system accomplish?
• You need to know what objects will form the system because ,
in the object oriented view point, objects are the primary
abstraction,.
• The main task of object modeling is to graphically show what
each will do in the problem domain, describes the structure
and the relationships among objects by visual notations, and
determine what behaviors fall within and outside the problem
domain.
40. Class Notation: Static Structure
• A class is drawn as a rectangle with three components separated by
horizontal lines.
• The top name compartment holds the class name, other general
properties of the class, such as attributes, are in the middle
compartment, and the bottom compartment holds a list of
operations.
• Either or both the attribute and operation compartments may be
suppressed.
• A separator line is not drawn for a missing compartment if a
compartment is suppressed; no inference can be drawn about the
presence or absence of elements in it.
• The class name and other properties should be displayed in up to
three sections.
• A stylistic convention of UML is to use an italic font for abstract
classes and a normal (roman) font for concrete classes.
42. Object Diagram
• A static object diagram is an instance of a class
diagram.
• It shows a snapshot of the detailed state of the
system at a point in time.
• Notation is the same for an object diagram and
a class diagram.
• Class diagram can contain objects, so a class
diagram with objects and no classes is an object
diagram.
43. Class Interface notation
• Class interface notation is used to describe the externally visible
behavior of a class; for example, an operation with public visibility.
• Identifying class interfaces is a design activity of OOSD.
• The UML notation for an interface is a small circle with the name of
the connected to the class.
• A class that requires the operations in the interface may be
attached to the circle by a dashed arrow .
• The dependent class is not required to actually use all of the
operations.
• For example, a person object may need to interact with the
BankAccount object to get the balance; this relationship is depicted
with UML class interface notation.
44. Binary association notation
• A binary association is drawn as a solid path connecting two
classes, or both ends may be connected to the same class.
• An association may have an association name.
• The association name may have an optional black triangle in
it, the point of the triangle indicating the direction in which to
read the name.
• The end of an association, where it connects to a class, is
called the association role.
marriedTo
45. Association Role
• A simple association –the technical term for it is binary association
– is drawn as a solid line connecting two class symbols.
• The end of an association, where it connects to a class, shows the
association role.
• The role is part of the association, not part of the class.
• Each association has two or more roles to which it is connected.
• The UML uses the term association navigation or navigability to
specify a role affiliated with each end of an association relationship.
• An arrow may be attached to the end of the path to indicate that
navigation is supported in the direction of class pointed to.
• An arrow may be attached to neither, one, or both ends of the path.
46. Qualifier
• A qualifier is an association attribute.
• For example, a person object may be associated to a bank object.
• An attribute of this association is the account#.
• The account# is the qualifier of this association.
• A qualifier is shown as a small rectangle attached to the end of an
association path, between the final path segment and the symbol
of the class to which it connects.
• The qualifier rectangle is part of the association path, not part of
the class.
• The qualifier rectangle usually is smaller than the attached class
rectangle.

0…1
47. Multiplicity
• Multiplicity specifies the range of allowable associated
classes.
• It is given for roles within association, parts within
compositions, repetitions, and other purposes.
• A multiplicity specification is shown as a text string
comprising a period separated sequence of integer
intervals, where an interval represents a range of
integers in this format
lower bound .. Upper bound
0..1
0 .. *
1..3, 7..10,15,19 .. *
account#
*
0…1
48. OR Association
• An Or association indicates a situation in which only one of several
potential association may instantiated at one time for any single
object.
• This is shown as a dashed line connecting two or more association,
all of which must have a class in common, with the constraint
string{0r} labeling the dashed line.
• In other words, any instance of the class may participate in, at most,
one of the association at one time.

Person
Company
{or}
49. Association Class
• An association class is an association that also has class properties.
• An association class in shown as a class symbol attached by a
dashed line to an association path.
• The name in the class symbol and the name string attached to the
association path are the same.
• The name can be shown on the path or class symbol or both.
• If an association class has attributes but no operations or other
association, then the name be displayed on the association path
and omitted from the association class to emphasize its “
association nature”.
• If it has operations and attributes, then the name may be omitted
from the path and placed in the class rectangle to emphasize its
“class nature”.
51. N-ary Association
• An n-ary association is an association among more than
two classes.
• An n-ary association is shown as a large diamond with a
path from the diamond to each participant class.
• The name of the association is shown near the diamond.
• The role attachment may appear on each path as with a
binary association.
• Multiplicity may be indicated; however, qualifiers and
aggregation are not permitted.
• An association class symbol may be attached to the
diamond by a dashed line, Indicating an n-ary association
that has attributes, operation, or associations.
53. Aggregation
• Aggregation is a form of association.
• A hollow diamond is attached to the end of the path
to indicate aggregation.
• The diamond may not be attached to both ends of a
line, and it need not be presented at all.
54. Composition
• It also know as the a-part-of, is a form of aggregation with
strong ownership to represent the component of a complex
object.
• Composition also is referred to as a part-whole relationship.
• The UML notation for composition is a solid diamond at the
end of a path.
• Alternatively, the UML provides a graphically nested form
that, in many cases, is more convenient for showing
composition.
• Parts with multiplicity greater than one may be created after
the aggregate itself but, once created, they live and die with
it.
• Such parts can also explicitly removed before the death of the
aggregate.
55.
56. Generalization
• Generalization is the relationship between a more general class and
a more specific class.
• Generalization is displayed as a directed line with a closed, hollow
arrowhead at the superclass end.
• The UML allows a discriminator label to be attached to a
generalization of the superclass.
• Ellipse(….) indicate that the generalization is incomplete and more
subclasses exit that are not shown.
• The constructor complete indicates that the generalization is
complete and no more subclasses are needed.
• If a text label is placed on the hollow triangle shared by several
generalization paths to subclasses, the label applies to all of the
paths.
• In other words, all subclasses share the given properties.
