Software Development Life Cycle

Software Development Life Cycle, SDLC for short, is a well-defined, structured sequence of stages in software engineering to develop the intended software product.

SDLC Activities

SDLC provides a series of steps to be followed to design and develop a software product efficiently. SDLC framework includes the following steps:

Communication

This is the first step where the user initiates the request for a desired software product. He contacts the service provider and tries to negotiate the terms. He submits his request to the service providing organization in writing.

Requirement Gathering

This step onwards the software development team works to carry on the project. The team holds discussions with various stakeholders from problem domain and tries to bring out as much information as possible on their requirements. The requirements are contemplated and segregated into user requirements, system requirements and functional requirements. The requirements are collected using a number of practices as given –

  • studying the existing or obsolete system and software,
  • conducting interviews of users and developers,
  • referring to the database or
  • collecting answers from the questionnaires.

Feasibility Study

After requirement gathering, the team comes up with a rough plan of software process. At this step the team analyzes if a software can be made to fulfill all requirements of the user and if there is any possibility of software being no more useful. It is found out, if the project is financially, practically and technologically feasible for the organization to take up. There are many algorithms available, which help the developers to conclude the feasibility of a software project.

System Analysis

At this step the developers decide a roadmap of their plan and try to bring up the best software model suitable for the project. System analysis includes Understanding of software product limitations, learning system related problems or changes to be done in existing systems beforehand, identifying and addressing the impact of project on organization and personnel etc. The project team analyzes the scope of the project and plans the schedule and resources accordingly.

Software Design

Next step is to bring down whole knowledge of requirements and analysis on the desk and design the software product. The inputs from users and information gathered in requirement gathering phase are the inputs of this step. The output of this step comes in the form of two designs; logical design and physical design. Engineers produce meta-data and data dictionaries, logical diagrams, data-flow diagrams and in some cases pseudo codes.

Coding

This step is also known as programming phase. The implementation of software design starts in terms of writing program code in the suitable programming language and developing error-free executable programs efficiently.

Testing

An estimate says that 50% of whole software development process should be tested. Errors may ruin the software from critical level to its own removal. Software testing is done while coding by the developers and thorough testing is conducted by testing experts at various levels of code such as module testing, program testing, product testing, in-house testing and testing the product at user’s end. Early discovery of errors and their remedy is the key to reliable software.

Integration

Software may need to be integrated with the libraries, databases and other program(s). This stage of SDLC is involved in the integration of software with outer world entities.

Implementation

This means installing the software on user machines. At times, software needs post-installation configurations at user end. Software is tested for portability and adaptability and integration related issues are solved during implementation.

Operation and Maintenance

This phase confirms the software operation in terms of more efficiency and less errors. If required, the users are trained on, or aided with the documentation on how to operate the software and how to keep the software operational. The software is maintained timely by updating the code according to the changes taking place in user end environment or technology. This phase may face challenges from hidden bugs and real-world unidentified problems.

Disposition

As time elapses, the software may decline on the performance front. It may go completely obsolete or may need intense upgradation. Hence a pressing need to eliminate a major portion of the system arises. This phase includes archiving data and required software components, closing down the system, planning disposition activity and terminating system at appropriate end-of-system time.

Software Development Paradigm

The software development paradigm helps developer to select a strategy to develop the software. A software development paradigm has its own set of tools, methods and procedures, which are expressed clearly and defines software development life cycle. A few of software development paradigms or process models are defined as follows:

Waterfall Model

Waterfall model is the simplest model of software development paradigm. It says the all the phases of SDLC will function one after another in linear manner. That is, when the first phase is finished then only the second phase will start and so on.

This model assumes that everything is carried out and taken place perfectly as planned in the previous stage and there is no need to think about the past issues that may arise in the next phase. This model does not work smoothly if there are some issues left at the previous step. The sequential nature of model does not allow us go back and undo or redo our actions.

This model is best suited when developers already have designed and developed similar software in the past and are aware of all its domains.

Iterative Model

This model leads the software development process in iterations. It projects the process of development in cyclic manner repeating every step after every cycle of SDLC process.

The software is first developed on very small scale and all the steps are followed which are taken into consideration. Then, on every next iteration, more features and modules are designed, coded, tested and added to the software. Every cycle produces a software, which is complete in itself and has more features and capabilities than that of the previous one.

After each iteration, the management team can do work on risk management and prepare for the next iteration. Because a cycle includes small portion of whole software process, it is easier to manage the development process but it consumes more resources.

Spiral Model

Spiral model is a combination of both, iterative model and one of the SDLC model. It can be seen as if you choose one SDLC model and combine it with cyclic process (iterative model).

This model considers risk, which often goes un-noticed by most other models. The model starts with determining objectives and constraints of the software at the start of one iteration. Next phase is of prototyping the software. This includes risk analysis. Then one standard SDLC model is used to build the software. In the fourth phase of the plan of next iteration is prepared.

V – model

The major drawback of waterfall model is we move to the next stage only when the previous one is finished and there was no chance to go back if something is found wrong in later stages. V-Model provides means of testing of software at each stage in reverse manner.

At every stage, test plans and test cases are created to verify and validate the product according to the requirement of that stage. For example, in requirement gathering stage the test team prepares all the test cases in correspondence to the requirements. Later, when the product is developed and is ready for testing, test cases of this stage verify the software against its validity towards requirements at this stage.

This makes both verification and validation go in parallel. This model is also known as verification and validation model.

Big Bang Model

This model is the simplest model in its form. It requires little planning, lots of programming and lots of funds. This model is conceptualized around the big bang of universe. As scientists say that after big bang lots of galaxies, planets and stars evolved just as an event. Likewise, if we put together lots of programming and funds, you may achieve the best software product.

For this model, very small amount of planning is required. It does not follow any process, or at times the customer is not sure about the requirements and future needs. So the input requirements are arbitrary.

This model is not suitable for large software projects but good one for learning and experimenting.

In 1908, Ford Motor Company’s first car, The Model T, used ethanol corn alcohol gasoline as fuel energy.

Since 2003, ethanol has grown rapidly as the oxygenating factor for gasoline. Ethanol replaced MTBE for oxygenating fuel, since almost all states now have banned MTBE, due to groundwater contamination, health and environmental concerns.

Ethanol blend fuels for gas powered engines have been around for over 100 years; Ethanol is now found at most public gas stations nationwide, due to mandates/laws and recommendations in the Alternative Motor Fuels Act (1988), Clean Air Act (1990), Energy Policy Act (2005) and most importantly – The Renewable Fuel Standard Program (RFS) – Signed September 2006.

The push for ethanol as an alternative to imported oil spurred the construction of 172 plants in 25 states by the end of 2008. But during 2009 falling oil prices has made ethanol less cost effective. More than 20 plants have recently closed.

Despite 10% being the universally accepted legal limit for ethanol in conventional gas-powered engines,

in March 2009 ACE, Growth Energy and 54 ethanol producers submitted a waiver application to increase E10 to E15.

ETHANOL HISTORY TIMELINE

1826 Samuel Morey developed an engine that ran on ethanol and turpentine.

1850’s During the Civil War, a liquor tax was placed on ethanol whisky, also called Moonshine, to raise money for the war.

1876 Otto Cycle was the first combustion engine designed to use alcohol and gasoline.

1896 Henry Ford built his first automobile, the quadricycle, to run on pure ethanol.

1920’s Standard Oil began adding ethanol to gasoline to increase octane and reduce engine knocking.

1908 The first Ford Motor Company automobile, Henry Ford’s Model T. was designed to use corn alcohol, called ethanol. The Model T ran on (ethanol) alcohol, fuel or a combination of the two fuels.

1940’s First U.S. fuel ethanol plant built. The U.S. Army built and operated an ethanol plant in Omaha, Nebraska, to produce fuel for the army and to provide ethanol for regional fuel blending.

1940’s to late 1970’s Virtually no commercial fuel ethanol was sold to the general public in the U.S. – due to the low price of gasoline fuel.

1975 U.S. begins to phase out lead in gasoline. MTBE eventually replaced lead.

Note: Later, between 2004 to 2006, MTBE banned in almost all states, due to groundwater contamination and health risks.

1980’s Oxygenates added to gasoline included MTBE (Methyl Tertiary Butyl Ether – made from natural gas and petroleum) and ETBE (Ethyl Tertiary Butyl Ether – made from ethanol and petroleum).

1988 Denver, Colorado, was the first state to mandate ethanol oxygenates fuels for winter use to control carbon monoxide emissions. Other cities soon followed.

1990 Clean Air Act Amendments – Mandated the winter use of oxygenated fuels in 39 major carbon monoxide non-attainment areas (based on EPA emissions standards for carbon dioxide not being met) and required year-round use of oxygenates in 9 severe ozone non-attainment areas in 1995.

1992 The Energy Policy Act of 1992 (EPAct) was passed by Congress to reduce our nation’s dependence on imported petroleum by requiring certain fleets to acquire alternative fuel vehicles, which are capable of operating on nonpetroleum fuels.

The Clean Air Act (1990) and Alternative Motor Fuels Act (1998 1992) contain provisions for mandating oxygenated fuel (RFG =Ethanol and MTBE). Requirements set for 2 types of clean-burning gasoline, RFG Federal Reformulated Gasoline and Wintertime Oxygenated Fuel.

1995 The EPA began requiring the use of reformulated gasoline year round in metropolitan areas with the most smog.

In Defense of Annual School Testing

By CHAD ALDEMAN FEB. 6, 2015

School testing

WASHINGTON — DURING a recent hearing by the Senate Education Committee, its Republican chair, Lamar Alexander of Tennessee, questioned whether the federal government’s annual standardized testing requirement, embodied in the No Child Left Behind law of 2001, may be too much. He pointed out that students now spend 1 to 3 percent of their school year taking federal, state and local tests in reading and math.

The concerns about standardized tests are bipartisan. Last fall former President Bill Clinton said, “I think doing one in elementary school, one in the end of middle school and one before the end of high school is quite enough.” This was the policy his administration championed in the law that predated No Child Left Behind. And recently teachers’ unions and the liberal Center for American Progress backed this type of “grade-span” approach for school accountability purposes.

The idea of less testing with the same benefits is alluring. Yet in practice it would actually roll back progress for America’s students.

Yes, test quality must be better than it is today. And, yes, teachers and parents have a right to be alarmed when unnecessary tests designed only for school benchmarking or teacher evaluations cut into instructional time. But annual testing has tremendous value. It lets schools follow students’ progress closely, and it allows for measurement of how much students learn and grow over time, not just where they are in a single moment.

It also allows for a much more nuanced look at student performance. For example, rather than simply looking at average overall school performance, where high performers frequently mask what’s happening to low achievers, No Child Left Behind focuses attention on the progress that groups of students are making within schools — a level of analysis that is possible only with annual data. To be confident that the test results aren’t pulled up or down by a few students and to minimize year-to-year variability, states usually consider only groups of at least 30 or 40 students. States are also able to average results over multiple years or across grades.

So, for instance, a school with 10 Hispanic students in each of grades three, four, five and six adds up to a group of 40, providing some accountability for what is happening to those students.

The grade-span approach would eviscerate the ability to look at particular groups of students within schools. Instead of having multiple grades over which schools could compile results, each school would be held responsible only for the performance of students in a single grade. Not only would this lower the quality of the data, but it would also raise the stakes of the tests: If you think the stakes are too high now, imagine being a fifth grader in a school where your score determines the results of the entire school.

Worst of all, under this approach, far fewer schools would be on the hook for paying attention to historically disadvantaged groups of students. A school with 10 Hispanic students in each grade would no longer be held accountable for whether those students were making sufficient progress, because the 10 fifth graders wouldn’t be enough to count as a meaningful population size.

To get a sense of how many students could become newly “invisible,” consider public elementary schools in Washington, D.C. Applying the same minimum group size currently used for entire schools to the fifth grade only, about half of the city’s 119 elementary schools with fifth graders taking math tests would not be held accountable for the progress of low-income or African-American students, because there aren’t enough of them in that grade to constitute a reliable sample size. For that same reason, less than 10 percent of schools would be responsible for Hispanic students or English language learners, and not a single elementary school would be accountable for the progress of students with disabilities.

Coincidentally, the push for limiting testing has sprung up just as we’re on the cusp of having new, better tests. The Obama administration has invested $360 million and more than four years in the development of new tests, which will debut this spring. Private testing companies have responded with new offerings as well.

Today’s eagerness to jettison our commitment to leave “no child behind” is a shame, not just because better tests are on the horizon, but also because it worked. Fourth and eighth grade achievement scores of black, Hispanic and low-income students have never been higher. High school graduation rates are at an all-time high. And researchers repeatedly link No Child Left Behind’s emphasis on traditionally underperforming groups to real improvements in schools around the country. The conversations that No Child Left Behind sparked are not easy, but they are essential.

That’s why it’s exactly the wrong time to accept political solutions leaving too many of our most vulnerable children hidden from view.

SPECIALISING IN ALLERGY TESTING & FOOD INTOLERANCE PROBLEMS


Welcome to Northwest Allergy Testing Clinics.

based in Chorley but covering Manchester, Wigan, Bolton, Blackburn, Preston and with easy access from Blackpool, Burnley and Warrington via the Motorway network.

The Northwest Allergy Testing Clinics have over 20 years experience in helping those suffering from Allergy and Food Intolerance problems.

The Northwest Allergy Testing Clinics have provided non-invasive Allergy and Food Intolerance testing services for over 20 years in the Manchester, and Lancashire areas and helped thousands of people improve their health by identifying and helping them eliminate many of the basic underlying imbalances which have caused their health problems.

We have successfully helped people suffering from a varying range of health problems including allergies, food intolerances, IBS, Chronic Fatigue, M.E, M.S, acne, eczema, fibromyalgia, asthma, constipation, arthritis, thyroid imbalance, anxiety, depression and more.


Identifying Your Allergies and Food Intolerances

Identifying the root cause of ill health is what we are concerned with. Ground breaking screening technology in the form of the Asyra Pro provides our practitioners with all of the information they need to do just that.

The Asyra� PRO system is the very latest in Computerised Electro Dermal (Skin) Screening (CEDS). It stress tests the body s energy system to screen for a whole range of potential problems.

Accredation

Asyra Pro is the most advanced technology in the field of energy medicine, and it is the FIRST Bio-Energetic health screening system in the world to have its hardware and software approved by the United States Food and Drug Administration (FDA),the largest Healthcare Organisation with responsibility for over 315 million people. The Asyra Electro-Dermal Screening System can be found in Hospitals and Doctors’ Surgeries throughout the USA.

The Technology is similar to a Electocardiogram, in that small pulses of electricity are passed throughout your body via the skin, (Electro-Dermal) and the results are displayed on a screen similar to a heart monitor; totally painless.

Results are displayed on the Monitor.

Allergy and Food Intolerance Testing

Is the food you are eating making you ill? Would you like help to change your diet, nutrition and lifestyle to get your health and life back on track? NORTH WEST ALLERGY TESTING covers the Whole of the North West,including Manchester,Bolton, Preston and has provided non-invasive testing services for over 20 years and helped thousands of people improve their health by identifying and helping them eliminate many of the basic underlying imbalances which have caused their health problems.

We have successfully helped people suffering from a varying range of health problems including allergies, food intolerances, IBS, Chronic Fatigue, M.E, M.S, acne, eczema, fibromyalgia, asthma, constipation, arthritis, thyroid imbalance, anxiety, depression and more.

Digestive Health/IBS Food Test

If your aim is to find out what’s causing your constant bloating, wind, acid reflux or your changeable bowel movements and want to stop it, great: you are in the right place.

Bowel health is the number one key to good health. The bowel is the main route for toxin elimination and is where many minerals, water and other substances are absorbed. It also plays a very important role in immunity and believe it or not the bowel is classed as the second brain! As well as carrying 1000’s of neurochemicals.

Lots of things can go wrong with digestion and bowel health. Some of them are relatively simple to deal with, and others a lot more complex. Over the years, we have seen many people with a diagnosis of IBS’ or myriad digestive symptoms which turned out to be caused by one of the factors below.

Food intolerance is the one of the leading causes, followed by lack of proper digestion and candida overgrowth. For constipation we have found that it is usually a fault of the vagus nerve, and recommend a course of Colonic Irrigation.

If you have access to a Mac or Linux server, chances are you may already have a really simple http load generating tool installed called Apache Bench, or ab. If you are on windows and have Apache installed, you may also have ab.exe in your apache/bin folder.

Suppose we want to see how fast Yahoo can handle 100 requests, with a maximum of 10 requests running concurrently:

It will then generate output as follows:

As you can see this is very useful information, it returned requests at a rate of 52.94 requests per second, the fastest request was 175ms, the slowest 224ms

So the next time you are tempted to whip out cfloop and GetTickCount to do some benchmarking on a piece of code, give ab a try, it’s easy to use, and will yield much more realistic results.

Because ab supports concurrency, this has two big advantages over cfloop. The main one is that it allows you to test how your code runs concurrently, this can help you identify any possible race conditions, or locking issues. Concurrent requests are also a more natural simulation of load than loops.

Suppose you wanted to test multiple url’s concurrently as well? You can do this by creating a shell script, with multiple ab calls. At the end of each line place an this makes the command run in the background, and lets the next command start execution. You will also want to redirect the output to a file for each url using filename For example:

The usage info from the ab version installed on my Mac (v2.3) is listed below. As you can see there are many useful options for outputting results, and sending additional data in the request.

Pete, I like your suggestion, by your method is completely incorrect. First, benchmarking Yahoo.com is useless for detecting their performance, as there are too many other variables to take into account. Second, your scripts will not gather correct result for two reasons: 1). You are benchmarking localhost, that will spike the load on the box, making the performance less accurate. and 2). You are running multiple benchmarks concurrently, which will also skew your results. You should always run your benchmarks from another machine, and run one at a time to isolate performance, all you’re doing right now it wasting electricity and getting useless results.

hello pete, while i was trying to use the ab cmd,i could not get my ip addr either by ipconfig or /sbin/ifconfig -a the problem is i get different ip addr’s. how should i check the performance?

Load Testing through Web Application #aspnet #load #testing


#

I would like to develop a web application using ASP.NET that will provide both Configuration and Execution/Control of Load testing in a custom way .

Instead of using VSTS (Manage Test Controllers), web application will create test controllers and test agents.

I would like to cover how parts in my web application:

How do we provision VSTS Load Test controller through an ASP.NET based web application?

How do we provision various VSTS Load Test Agents through web application?

How do we monitor and retrieve test results/reports on web application?

Kindly provide some pointers / reference article/ links / code on how to create a web application for performing load testing.

Thanks in advance.

We need to create a web test for our Asp.Net app, then add it to the load test. This may help

A penetration test is done to evaluate the security of a computer system or network by simulating an attack by a malicious user / hacker. The process involves active exploitation of security vulnerabilities that may be present due to poor or improper system configuration, known and / or unknown hardware or software flaws, or operational weaknesses in process or design.

This analysis is carried out from the position of a potential attacker, to determine feasibility of an attack and the resulting business impact of a successful exploit. Usually this is presented with recommendations for mitigation or a technical solution.
