This document provides an overview of software engineering. It begins by discussing the emergence of software engineering as a discipline due to the "software crisis" of the 1970s. It then covers various software engineering processes and lifecycle models, including sequential models like waterfall and iterative models like prototyping and spiral. Requirements engineering methods like elicitation, analysis and specification are also summarized. Finally, it discusses the function-oriented and object-oriented approaches to software development.
This lecture provide a review of requirement engineering process. The slides have been prepared after reading Ian Summerville and Roger Pressman work. This lecture is helpful to understand user, and user requirements.

Software engineering task bridging the gap between system requirements engineering and software design.
Provides software designer with a model of:
system information
function
behavior
Model can be translated to data, architectural, and component-level designs.
Expect to do a little bit of design during analysis and a little bit of analysis during design.
Objectives:
1. To understand the different processes in the realm of ‘Requirements Engineering’.
2. To see the challenges in requirements development and the importance of getting requirements right in an IT project.
3. To understand the different techniques used in different phases and processes of requirements development and management.
This lecture provide a detail concepts of user interface development design and evaluation. This lecture have complete guideline toward UI development. The interesting thing about this lecture is Software User Interface Design trends.

The importance of software since there is were the motivation for software engineering lies and then and introduction to software engineering mentioning the concept and stages of development and working in teams
this pdf file includes software development life cycle, requirement analysis and specification, project management, design, coding, testing, maintenance and quality reuse and case tools.
Software engineering is an engineering branch associated with development of software product using well-defined scientific principles, methods and procedures. The outcome of software engineering is an efficient and reliable software product.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
Macroeconomics- Movie Location
This will be used as part of your Personal Professional Portfolio once graded.

17. Approaches to Software
Engineering
System for which software is to be developed is
successively broken down (decomposed) into parts
and arranged in to hierarchy.
Decomposition is a convenient way of handling any
complex problem.
TWO approaches to Software Engineering
1. Function-Oriented (FO) Approach
2. Object-Oriented (OO) Approach
Similarity: System factored into parts in both approaches
Difference: lies in the basis on which the system is factored

In OO approach, system functionality is expressed in terms of
operations or services associated with each object.
27. Steps of OOA
•Define User View of Requirements
•Identify Analysis Objects and their Characteristics
•Determine Object Dynamics
•Determine Object Interactions and relationship
Diagrams used in OOA.
Use case diagram Describes how users interact with processes
Class diagram It is used to refine the use case diagram and define a
detailed design of the system
State diagram Represents different states that objects in the system
undergo during their life cycle
Activity diagram Describes the process flow of the system
Sequence diagram Represents interaction between objects
Collaboration diagram Groups together interactions between objects.

31. SSAD vs OOAD
Same basic steps
– Understand the problem
– Specify requirements (WHAT)
– Design the solution (HOW)
– Write the code
– Test and deploy
Similar types of tasks
– Elicitation of requirements
– Documentation of requirements
– Identification of software modules
– Design of software modules
– Acceptance tests
Similar project management issues
e.g. Planning, Estimating, Monitoring & Control, Communicating
