1. CASE tools are software used to support various activities in the software development process by automating some activities and providing information about the software.
2. CASE tools have several key components including diagramming tools, central repositories, report generators, documentation generators, and code generators.
3. CASE tools can be categorized as upper CASE tools which focus on analysis, lower CASE tools which focus on programming and integration, or integrated CASE tools which support the entire process.
Interfaces allow for separation of concerns and evolution of a system over time without disrupting existing structures. They specify a service that a class or component provides without implementing any structure or behavior. Common modeling techniques for interfaces include identifying seams between components, modeling static and dynamic types, using packages to group logically related elements, and creating architectural views to visualize different aspects of a system.
Package diagrams allow developers to organize model elements such as use cases, classes, and other packages. A package is a general mechanism for grouping these elements and can be rendered as a tabbed folder. Elements within a package can have public or private visibility. Relationships between packages include dependency and generalization. Dependency relationships indicate that one package depends on another, while generalization shows a parent-child relationship. Packages can be merged to combine their contents. Common architecture styles for organizing packages include decomposition, uses, generalization, and layered. These styles aid in tasks like planning, reuse, and managing complexity.
The document discusses package diagrams in UML. It explains that package diagrams show the high-level organization of systems and can contain other UML diagrams. Package diagrams use packages and dependencies. Packages represent modules and can contain classes, diagrams, and other elements. Dependencies show relationships between packages like import and access relationships. The document then provides an example of constructing a package diagram for an online order tracking system.

The document discusses different types of software metrics that can be used to measure various aspects of software development. Process metrics measure attributes of the development process, while product metrics measure attributes of the software product. Project metrics are used to monitor and control software projects. Metrics need to be normalized to allow for comparison between different projects or teams. This can be done using size-oriented metrics that relate measures to the size of the software, or function-oriented metrics that relate measures to the functionality delivered.
Object-oriented analysis and design (OOAD) is a popular approach for analyzing, designing, and developing applications using the object-oriented paradigm. It involves modeling a system as a group of interacting objects at various levels of abstraction. Key concepts in OOAD include objects, classes, attributes, methods, encapsulation, inheritance, polymorphism, and relationships like association, aggregation, and composition. Common OOAD techniques include use case diagrams, which show interactions between actors and the system, and class diagrams, which describe the structure and behavior of system objects and their relationships.
This document provides an overview of agile methodology and compares it to traditional waterfall development. It describes waterfall development as a sequential process with distinct phases completed one after another.

It uses diagrams to depict both the static structure and dynamic behavior of a system. The main types of UML diagrams are structural diagrams, which show the structure of a system, and behavioral diagrams, which show the behavior of a system. Some key UML diagrams include class diagrams, which show system classes and relationships, use case diagrams which illustrate functional requirements, and sequence diagrams which depict the interactions between objects. UML helps software engineers, business people, and architects with modeling, design and analysis of systems.

TrustArc Webinar - Your Guide for Smooth Cross-Border Data Transfers and Glob...TrustArc
Global data transfers can be tricky due to different regulations and individual protections in each country. Sharing data with vendors has become such a normal part of business operations that some may not even realize they’re conducting a cross-border data transfer!
The Global CBPR Forum launched the new Global Cross-Border Privacy Rules framework in May 2024 to ensure that privacy compliance and regulatory differences across participating jurisdictions do not block a business's ability to deliver its products and services worldwide.
To benefit consumers and businesses, Global CBPRs promote trust and accountability while moving toward a future where consumer privacy is honored and data can be transferred responsibly across borders.
This webinar will review:
- What is a data transfer and its related risks
- How to manage and mitigate your data transfer risks
- How do different data transfer mechanisms like the EU-US DPF and Global CBPR benefit your business globally
- Globally what are the cross-border data transfer regulations and guidelines
Lee Barnes - Path to Becoming an Effective Test Automation Engineer.pdfleebarnesutopia

2. UML
What is UML
History of UML
Importance of software model
Various diagram of UML
Use of UML Diagram
3. What is UML
Unified modeling language (UML) for
visualizing, specifying, constructing, documenting of
artifact of a software system
The blueprint of a system is written in it
UML is also used for modeling non-software system
It is standard for building object oriented and
component based software system
UML is a notation system though which we can
visualize a model of a system
It describe only design or structure of system
4. History of UML
In early stages of model driven development there was
a great need for some universal approach for
modeling a software system
As deferent 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 )
5. History of UML
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
6. Versions of UML

8. New in UML2.0
Changes in activity diagram
The first noticeable change is that the nodes in activity
diagrams are no longer called activities. They are
called actions
These constraints are shown as notes attached to the
action with the appropriate stereotype symbol
In UML 2.0, an action will not fire until each of the
incoming flows triggers
new to UML 2.0, is the time signal. A time signal is
received because a certain amount of time has passed
9. New in UML 2.0
The final addition to the basic activity diagram is the
connector.
The connector indicates that a flow moves from one
activity diagram to another.
UML 2.0 contains three new ways to group and
decompose actions
UML 2.0 introduces activity partitions to handle
problems
10. New to UML 2.0
Changes in Class diagram
Visibility is a single character representing whether the
attribute is visible to the
public (+),
private (-),
protected (#),
or package (~).
The slash (/)
Indicates whether the attribute is derived
11. Use Case diagram
Changes in use case diagram
The exact extension point that is used between the two
use cases
12. Importance of Software Model
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
13. UML 2.0 Diagrams
UML is divided in to two General set of Diagrams
Structured modeling diagrams
It depicts the static view of the model
Behavioral modeling diagram
Behavior diagrams depicts the varieties of interaction
within a model as it 'executes' over time
15. Behavioral Modeling Diagram
Use Case Diagram
Activity Diagram
State Machine Diagram
Communication Diagram
Sequence Diagram
Timing Diagram
Interaction Over view Diagram
16. Class diagram
It depicts the static view of a model
It is the basic building block of the object oriented system
It illustrate the relation ship between classes in the system
Class diagram consist of:
Class diagram
It consist of rectangle with three compartments
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)
17. Class diagram
+ 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)
18. Class diagram
Class diagram show relationship between class
Generalizations
A generalization is used to indicate inheritance.
Aggregations
Aggregations are used to depict elements which are
made up of smaller components
Example composite-Aggregation
Address book and contact group and contacts
23. Object diagram
An object diagram may be considered a special case of
a class diagram
Object diagrams emphasize the relationship between
instances of classes at some point in time
Object is shown by a rectangular with classifier name
in the center f rectangular and under line
Object diagram shows complex relationship between
classes
It is useful if we feel classes as more abstract abstract
25. Package diagram
Package diagram are used to divide the model into logical
containers and their interaction
Package diagram is used to show the high level view of the
system
As software system have a lot of class (building block in
object oriented system) to organize those in a package to
show higher level view of the system
Package is used to structure your classes
Package diagram is used divide the complex system in to
modules
And In large system to show the large elements and their
communication
It is used in large and complex systems
27. Package diagram
A «merge» connector between two packages defines
an implicit generalization between elements in the
source package
28. Component diagram
Component diagram shows the system in term
modules
Components can be represented as
encapsulated, reusable, replaceable
Component can be used as building block of the
system
Component communicate with each other through
interfaces
Component can do the same thing as class
30. Component diagram
Component diagram are shown same as class instead
of sign in the component diagram
component port
required interface provided interface
31. Component diagram
Ball represented provided interfaces
Provided interfaces that’s a component implements
Required interfaces that a component required to
provide its functionality
Port is door way through communication pass
Component is useful to show the system in term of
module
32. Deployment diagram
Deployment diagram model the physical layout of the
system mapping software artifact to hardware in
which they execute and their communication
Deployment diagram is used to show the physical
deployment of the system
Deployment diagram has node which may be a hard
ware or any device that host the software and my be a
software that host another software (example
operating system)
Artifacts shows the software that is implemented on
the hardware
35. Behavioral Modeling Diagram
Use Case Diagram
Activity Diagram
State Machine Diagram
Communication Diagram
Sequence Diagram
Timing Diagram
Interaction Over view Diagram
36. Use Case Diagram
A USE CASE is an interaction between a system and external
stimulate, that could a human and may be an external system
A USE CASE diagram is an purposed functionality of the system
USE CASE diagram is used to show a discrete unit of work
It is used at early stages of model
It is the simplest diagram
Example of USE CASE for a Stock trading system
Open an account
Close an account
Deposit funds
Draw funds
37. Use Case diagram
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
38. Use Case diagram
USE CASE diagram have relationship
Include
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 use case
every time the check funds use case is included to
complete the place order use case
place order(use case) <include > (check funds) use case
39. Use Case diagram
USE CASE diagram have relationship
Extends
It is relationship between a use case to another use case
In which a extends use case in exceptionally called for
example, if before modifying a particular type of customer
order, a user must get approval from some higher authority
then the <Get Approval> use case may optionally extend
the regular <Modify Order> use case.
Modify order(use case) <extends> (Get Approved) use case
40. State diagram
It shows the dynamic view of the system
It is also called state chart or state machine diagram
It shows the behavior of the system in response to
some external stimulate
State diagram is consist of:
States
super states
pseudo state
Transition
41. State diagram
State and super states are represented as a rounded
box and sub states are in super state
Pseudo Psedu state
State Trantion
Super State Sub State 1 Transient sub state 2
43. Activity diagram
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
44. Activity diagram
portions line
starting point
Actions
Decision node
action
actions
End point
45. Activity diagram
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
46. Timing diagram
Timing diagrams are used to display the change in state or value of one
or more elements over time.
A state lifeline shows the change of state of an item over time
The X-axis displays elapsed time in whatever units are chosen
The Y-axis is label with a given list of states
47. Communication diagrams
A communication diagram, formerly called a
collaboration diagram
It shows similar information to sequence diagrams
Communication diagram shows the objects
relationship
Objects are shown with association connectors
between them
Messages are added to the associations and show as
short arrows pointing in the direction of the message
flow
49. Interaction Overview diagram
Interaction diagram is the combination of activity and sequence
diagrams
It allow interaction fragments to be easily combined with
decision points and flows
An interaction overview diagram is a form of activity diagram in
which the nodes represent interaction diagrams.
Interaction diagrams can include
sequence, communication, interaction overview and timing
diagrams.
Most of the notation for interaction overview diagrams is the
same for activity diagrams. For
example, initial, final, decision, and join nodes are all the same.
Interaction overview diagrams introduce two new elements:
interaction occurrences and interaction elements.
50. Interaction Overview diagram
Interaction occurrences are references to existing
interaction diagrams.
An interaction occurrence is shown as a reference
frame; that is, a frame with quot;refquot; in the top-left corner
Interaction elements are similar to interaction
occurrences, in that they display a representation of
existing interaction diagrams within a rectangular
frame
53. Interaction Overview
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.
The above example depicts a sample sale process
54. Sequence diagram
Sequence diagrams provide a graphical representation
of object interactions over time
One sequence diagram typically represents a single
Use Case 'scenario' or flow of events.
The diagrams show the flow of messages from one
object to another, and as such correspond to the
methods and events supported by a class/object.
