Process models are not perfect, but provide road map for software engineering work. Software models provide stability, control, and organization to a process that if not managed can easily get out of control
Software process models are adapted to meet the needs of software engineers and managers for a specific project.
Software life cycle model: The descriptive and diagrammatic representation of the software life cycle
It represent all the activities performed on software product from the inception to retirement
It also depicts the order in which these activities are to be undertaken
More than one activity can be carried out in a single phase
The primary advantage of adhering to a life cycle model is that it encourages development of software in a systematic and disciplined manner
When a program is developed by a single programmer ,he has the freedom to decide the exact steps through which he will develop the program
Iterative Linear Sequential Model

Iterative Linear Sequential Model
The systems development life cycle (SDLC), also referred to as the application development life-cycle, is a term used in systems engineering, information systems and software engineering to describe a process for planning, creating, testing, and deploying an information system. @ paghdalyogesh@gmail.com
perfect for college presentation to speak about the prototype model for 5 minutes or can be extended according to the explanation given by the student or presenter about the diagram that shows the phases,
SDLC is the acronym of Software Development Life Cycle. It is also called as Software development process. The software development life cycle (SDLC) is a framework defining tasks performed at each step in the software development process.
A software process model is an abstraction of the software development process. The models specify the stages and order of a process. So, think of this as a representation of the order of activities of the process and the sequence in which they are performed

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

Why React Native as a Strategic Advantage for Startup Innovation.pdfayushiqss
Do you know that React Native is being increasingly adopted by startups as well as big companies in the mobile app development industry? Big names like Facebook, Instagram, and Pinterest have already integrated this robust open-source framework.
In fact, according to a report by Statista, the number of React Native developers has been steadily increasing over the years, reaching an estimated 1.9 million by the end of 2024. This means that the demand for this framework in the job market has been growing making it a valuable skill.
But what makes React Native so popular for mobile application development? It offers excellent cross-platform capabilities among other benefits. This way, with React Native, developers can write code once and run it on both iOS and Android devices thus saving time and resources leading to shorter development cycles hence faster time-to-market for your app.
Let’s take the example of a startup, which wanted to release their app on both iOS and Android at once. Through the use of React Native they managed to create an app and bring it into the market within a very short period. This helped them gain an advantage over their competitors because they had access to a large user base who were able to generate revenue quickly for them.

Fundamentals of Software Engineering
1. Prescriptive Process models
• Waterfall Model.
• Incremental Process Model.
• Evolutionary Process Model.
• Concurrent model
1
2. Prescriptive Process models
Waterfall Model
• Oldest software lifecycle model & best understood by
upper management
• Used when requirements are well understood and risk
is low
• Work flow is in a linear fashion (i.e., sequential)
• Used often with well-defined adaptations or
enhancements to current software 2
4. Waterfall Model
Problems
• Real projects rarely follow sequential flow.
• Difficult for customers to state all requirements
explicitly and up front
• Requires customer patience because a working
version of the program doesn't occur until the final
phase
• Doesn't support iteration, so changes can cause
confusion and Leads to “blocking states”.
Useful
• Where requirements are fixed and is to proceed to
completion in a linear manner.
4
5. Prescriptive Process models
Incremental Process Model
• Combines elements of linear and parallel process
flows.
• It delivers a series of releases, called increments that
provide progressively more functionality for the
customer as each is delivered
• The first increment is often a core product.
• The plan addresses the modification of the core
product to better meet the needs of the customer and
the delivery of additional feature and functionality.
• It focuses on the delivery of an operational product
with each increment. 5
6. Incremental Process Model
• It is useful when staffing is unavailable for a
complete implementation.
• Increments can be planned to manage
technical risks.

Modeling (analysis, design)
Construction (code, test)
Deployment ( delivery, feedback)
Delivery of 1st Increment
7. Evolutionary Process Model
• Software, like Complex systems evolve over a period of
time
-Business and product requirements often change as development
proceeds.
- tight market deadlines make completion of a comprehensive software
product impossible, but a limited version must be introduced to meet
competitive or business pressure
- a set of core product or system requirements is well understood, but the
details of product or system extensions have yet to be defined.
• Evolutionary models are iterative.
• Evolutionary Process Model produce an increasingly
more complete version of the software with each
iteration.
• Specification, development and validation are
interleaved.
7
9. Evolutionary Process Model
Prototyping
• It assists you and stakeholders to better understand what is to
built when requirements are fuzzy.
• Prototyping paradigm
-begins with communication.
- planned quickly and modelling occurs
- quick design focuses on a representation of those aspects of the
software that will be visible to end users.
• It serves as a mechanism for identifying software
requirements.
9
11. Prototyping Model
Problems
• Overall software quality or long-term maintainability
is not considered.
• As a Software Engineer make implementation
compromises in order to get a prototype working
quickly.
Useful
• The customer get feel for the actual system and
developers get to build something immediately
• Key here is all the stakeholders should agree that the
prototype is built to serve as a mechanism for defining
requirements. 11
12. Evolutionary Process Model
Spiral development
• Originally proposed by Barry Boehm.
• It couples the iterative nature of prototyping with the
controlled and systematic aspects of water fall model.
• Process is represented as a spiral rather than as a
sequence of activities with backtracking.
• Each loop in the spiral represents a phase in the
process.
• No fixed phases such as specification or design -
loops in the spiral are chosen depending on what is
required.
• Risks are explicitly assessed and resolved throughout
the process. 12
13. Spiral model
• It is a realistic approach to the development of
large-scale systems and software.
• The software evolves as the process progresses, the
developer and customer better understand and react
at each evolutionary level.
• It uses prototyping as a risk reduction mechanism.
• It demands considerable risk assessment expertise
and realise on this expertise for success.
13
15. Evolutionary development
• Problems
– Do not establish the max. speed of the evolution.
– Systems are often poorly structured;
– Special skills (e.g. in languages for rapid prototyping)
may be required.
– Proj. mgmt. and estimation technique do not fit
completely
• Applicability
– For small or medium-size interactive systems;
– For parts of large systems (e.g. the user interface);
– For short-lifetime systems.
15
16. Concurrent Model
• The concurrent development model sometimes called
Concurrent Engineering.
• It allows team to represent iterative and concurrent
elements of any of the process models.
• All software engineering activities exist concurrently but
reside in different states.
• Concurrent modeling defines a series of events that will
trigger transitions from state to state for each of the
activities.
• Concurrent modeling is applicable to all types of
software development and provide an accurate picture of
the current state of a project. 16
