The document discusses the Unified Modeling Language (UML), which was created to provide a standard modeling language for visualizing, specifying, constructing, and documenting software systems. It originated from the need for a universal modeling approach, and was formed by merging the modeling languages of Booch, Rumbaugh, and Jacobson. The Object Management Group later standardized UML in 1997. UML includes structural diagrams like class and component diagrams and behavioral diagrams like use case and activity diagrams to model different aspects of a system.

Unified Modeling Language (UML) is a general purpose modelling language. The main aim of UML is to define a standard way to visualize the way a system has been designed. It is quite similar to blueprints used in other fields of engineering.
UML is not a programming language, it is rather a visual language. We use UML diagrams to portray the behavior and structure of a system. UML helps software engineers, businessmen and system architects with modelling, design and analysis. The Object Management Group (OMG) adopted Unified Modelling Language as a standard in 1997. Its been managed by OMG ever since. International Organization for Standardization (ISO) published UML as an approved standard in 2005. UML has been revised over the years and is reviewed periodically.

UML Model for Project Introduction
System design is a process that helps to conceptualize the software system requirements into a software implementation. It involves taking the user requirements and using it to define system architecture, interfaces and modules for the system. The most widely used method for software system design today is Object-Oriented analysis and design methods for their reusability and easy way of expressing relationship between system components(Martin, 2011). To be able to efficiently utilize the power of object-oriented analysis and design methods you need to use its standard language, Unified Modeling language (UML). UML is a general purpose modeling language that is used to provide a standard way to visualize the design of a system. UML is rich of modeling notations and methods that are used to create different diagrams to represent structural and behavior information of the system (Wazlawick, 2014). Example of this diagrams include class diagram, use case diagram, deployment diagrams, activity diagram, state, object, and sequence among other.
The diagram in the following sections represents the structural and behavior of the Online ordering system. Use cases
Use case diagram are used to represent a user’s interaction with the system hence showing the relationship between the system and its users. Use cases identify the different actors (users) of the system and the different ways (use cases) they interact with the system. The use case diagram below shows the two main users of the online orders system and how the use the system.

UML Class diagram are static structure diagram used to describe the structure of software system by showing classes, operations, their attributes and the relationship among them. Classes form the main building block of Object Oriented modeling and hence class diagram help to conceptualize the general structure of the system that can later be translate into programming code. Classes in class diagram represent the main elements in the application to be programmed (Booch, 1994).
The diagram below show the class diagram for the recommend online ordering system. Boxes represent classes. Boxes are supposed to have three compartments to complete the represent class information in full, one for class name, second for class attributes and the third for class operations. The diagram below shows a simple representation of classes. The lines represent links between classes and show the kind of relationship between classes. For example user is generalization for customer and sales. Customer makes o.

0x01 - Newton's Third Law: Static vs. Dynamic AbusersOWASP Beja
f you offer a service on the web, odds are that someone will abuse it. Be it an API, a SaaS, a PaaS, or even a static website, someone somewhere will try to figure out a way to use it to their own needs. In this talk we'll compare measures that are effective against static attackers and how to battle a dynamic attacker who adapts to your counter-measures.

3. In early stages of model driven development
there was a great need for some universal
approach for modeling a software system
As different people understand the notation
in different way if there is no universal
model approach
At that time brooch, rumba, Jacobson gave
there theories and universally accepted
All of three decided to build a notation
language by merging all of three language
and out product of that was UML (unified
modeling language )
4. In 1997 OMG (Object management group) a non
profit organization standardized the UML
Since then they are making improvement in UML
Released versions of UML
1.1 November 1997
1.2 July 1998
1.3 March 2000
Latest >> 2.4.1 August 2011
5. UML stands for Unified Modeling Language
The Art of Software Modeling
The UML represents a collection of best
engineering practices that have proven successful
in the modeling of large and complex systems.
Standard language for specifying, visualizing,
constructing, and documenting the artifacts of
software systems, business modeling and other
non-software systems.
6. The UML is a very important part of developing
object oriented software and the software
development process.
Using the UML helps project teams
communicate, explore potential designs, and
validate the architectural design of the
software.
UML is a notation system though which we can
visualize a model of a system
7. If software is complex need of model
If a system is developed by the hundreds of
People there is also need of model for smooth
communication and understanding the software
system
mange complexity in design
build and design architecture
Visualize the implementation
Design secure , scalable, robust and extendable
system
8. UML is divided in to two General set of
Diagrams
Structured modeling diagrams
(It shows the static view of the model)
Behavioral modeling diagram
(Behavior diagrams shows the varieties
of interface within a model as it
'executes' over time)
10. Use Case Diagram
Activity Diagram
State Machine Diagram
Interaction Diagram
Communication Diagram
Sequence Diagram
Timing Diagram
Interaction Over view Diagram

13. It shows the static view of a model
It is the basic building block of the object oriented
system
It show the relation ship between classes in the system
Class diagram consist of:
It consist of rectangle.
Class name is added in this this compartment
(teacher)
Class attribute is added in this department (name )
Class methods are placed in this compartments
(teach)
14. + sign with attributes or methods shows class
member are public
- sign with attribute or methods shows class
members are
private
Class name is added in this this compartment (teacher)
Class attribute is added in this department (-name
Class methods are placed in this compartments
(+teach)
16. An object diagram may be considered a
special case of a class diagram
Object diagrams highlight the relationship
between classes at some point in time
Object is shown by a rectangular with
classifier name in the center of rectangular
and under line
Object diagram shows complex relationship
between classes
It is useful if we feel classes as more abstract
17.
18. UML component diagrams shows the
dependencies among software components,
including the classifiers that specify them
(for example implementation classes) and
the object that implement them; such as
source code files, binary code files,
executable files, scripts and tables.
19.
20.
21. This diagram consist of:
Actor
It is represented by a human, either the actor is a
human
Or and external system.
Actor is role
Use case
It is represented by an oval shape with
title in it
22. USE CASE diagram have relationship
It is relationship between a use case to another
use case
In which a include use case in necessary to
perform other use case,
for example in place order every time the
check funds is included to complete the place
order
place order(use case) <include >
(check funds) use case
24. Activity diagram is also dynamic view of the
system
Activity diagram similar to flow charts
Each activity consist of series of actions
Actions are represented by oval shapes
Actions are connected by arrows
Arrow shows the flow of the activity diagram
Activity diagram also shows decision points
called decision node
25. Activity diagram is used to describe the
individual use case
Use case is used to describe the user goal
Activity diagram can be used where we can
use flow charts
27. All the same controls from activity diagrams
(fork, join, merge, etc.)
Controls can be used on interaction overview
diagrams to put the control logic around the
lower level diagrams.
