Software Development Life Cycle – Introduction Model Stages and Advantages

What is the Software Development Life Cycle (SDLC)?

SDLC or Software Development Life Cycle is essentially the process or phases of a model or methodology, which software engineers and developers follow in developing an application or software. In simpler words, it is a process consisting of a series of planned activities for planning, creating, testing, deploying and maintenance of software.

SDLC is often referred as software development process, as it consists of all tasks, which needs to be followed while developing an application or software. SDLC is followed within IT development companies to develop, alter, replace or enhance the performance of the software. ISO/IEC 12207 is an international standard for SDLC, which ensures high quality of the newly developed software. It also helps IT development companies in improving the overall quality of their software development services.

What are the major SDLC Models, followed in the IT Industry?

There are various SDLS models, which are currently followed in the IT Industry. Often referred as ‘Software Development Process Models’, all the process models follow unique software development steps, ensuring 100% success of the development projects.

What are the different stages of SDLC?

Stage 1:

Planning and Requirement Analysis

This is the most important stage in the SDLC. This stage needs input from the customers, sales team, industry experts, a marketing team and their survey reports. After which, senior business managers and developers of a software development company plan the project approach and the development model.

Stage 2:

Designing

After the analysis of requirements and finalizing the Design Document Specification (DDS), the product architecture is designed by an expert team. This architecture has to stand upon various parameters such as budget, time, product robustness, risk assessment and design modularity, after which it is considered for the development.

Stage 3:

Development

The actual development of the software or application starts at this stage. The team of engineers and developers follow the coding guidelines set by the organization and use different tools for code generation. The programming code is generated as per the details documented in the DDS. The developers use different high level programming languages as per the requirement.

Stage 4:

Testing

In this stage, the final product goes through a pre-defined road of testing, where defects or bugs in the product are reported and then fixed by the developers. This stage ensures that the final product meets the highest quality standards, which are accepted worldwide.

Stage 5:

Deployment

At this stage, the final product is deployed at the client base. At times, the software is integrated with the client’s current application and database. All the deployment and integration works are done under the guidance of expert software engineers and developers.

Stage 6:

Maintenance & Support

Most of the reputed IT development companies also provide complete maintenance and technical support, post deployment of the final product at client base.

Be True To Your Finances

Money will never be enough. Whether you earn $100 or more there will always be room for more and more needs and wants in your life. Currently I earn twice as much as I used to earn two Years ago but my expenses are also twice as much. If you do not watch out on the trend you take with your needs and your income, you will get frustrated and think the problem is with money yet you are the one causing the problem.

I prayed for wisdom on how to spend wisely to avoid pitfalls and I got help. I have not reached the peak but so far I am very happy with the way I manage my finances. At this point in time I will give you tips on how to manage your needs and wants in regards to money and avoid going overboard. The secret is to live within your means and this is how

1. Write down your daily needs and wants that you spend on and divide the needs and wants into three categories; Daily, Weekly and Monthly

2. Beside each category write down the needs and wants and how much you spend on them. Be honest with yourself do not underestimate or overestimate, you have to be on point. If you over/under estimate you will not make it. Prices do not change within a short period of time so you will have to go to a grocery shop or supermarket to get the exact price of the commodity you buy daily, weekly or monthly.

3. Find totals for each category, for example, your daily category must be multiplied by thirty for you to know how much you spend in a month and the weekly budget by four. Add up your totals and see how much you spend.

4. If your budget exceeds what you earn, then you have to review your needs and wants and be disciplined enough to reduce your wants at this moment and check whether your needs may also be overboard. If you find that your needs are expensive, then you should find a place where the same needs can be bought less expensive, for example; instead of buying tomatoes or other raw vegetables and fruits from a supermarket try getting them from a local vendor. If the house you are staying in is eating up your money move to a descent less expensive apartment.

5. Stick to this budget and consult it regularly, go back and check whether you are on track or off track. Try this for just a month and you will see a very big positive difference and you will even manage to save money.

A Short History of Sports Photography

The history of sports photography is tightly related to the trends of sport gaining popularity throughout human history. The technology of photography from the early 1800s onward leaped forward in bounds and aided an emerging media, sporting journalism.

The inspiration of athletics and sport in art can certainly be seen in the work of the ancient Greek masters of sculpture, however this type of expression was not as prevalent in modern sporting venues until the invention of wet-collodion and dry-plate photographic processes. These processes allowed for posed studio images on glass plates and tin-types, but were just not ‘fast’ enough for the ‘stop-action’ images we are used to seeing today.

As the 19th Century was coming to a close, in the 1880s scientific motion studies of athletes in action were produced in the United States and Germany, the technology was still not considered on the sporting field. This all changed with the advancement of photography and sports journals in the last part of the century. As the first sports journals began to appear around 1900, the public became more and more interested in the sports image, which often would include images of players on the tennis green, golfling or on the hunt for wild game.

In the history of sports photography the earliest of contributors were more concerned with the activities of the country elite, but by the end of World War I, readers of sporting journals were becoming interested in the professional athletes of American baseball and tennis. The majority of these early images were of prominent players in posed situations, giving te sense of action. Baseball players were posed with bat in hand at the plate, teams were lined up for group shots and so forth, however the ‘action’ shot was still not widely seen.

With the 1930s more and more images of athletes in action were appearing in magazines, assisted in their growth through camera systems allowing photographers shutter speeds up to 1/1000th of a second. This gave way to styles highlighting blurred subjects suggesting movement and ‘stop-action’ images of the athlete in activity. Photographers began adopting signature styles and the popularity of the genre began to grow rapidly as the public began to expect the excitement of seeing their favored athletes in ‘action.’

In 1954, Sports Illustrated – the vaunted digest of sports and athletics – premiered and suddenly the position of being a sports photographer became even more engrained in the public eye. The magazine highlighted the exploits and professional and amateur athletes the world over, increasing the need for the art form and those who practiced it. By this point, technology had more or less caught up with demand, with the advent of small, compact single lens reflex (SLR) cameras and the fast shutter speeds offered in the models. The history of sports photography is strongly tied to lens technology, as well, had advanced to offer the photographer a wide choice of methods to compress perspective and using depth of field for dramatic effect.

Niche Marketing Strategies for Home Business

In today's intensely competitive business environment, it is usually difficult to stay afloat, particularly when you're a small home business owner working on shoestring budget. You do not have access to viable means and amenities to compete directly with large business houses and serve a broad spectrum of consumers.

Once, you've identified your niche market, conduct a thorough competitive analysis to identify your direct competitors as well as determine what niche marketing strategies they are using to stay ahead.

It is usually believed that a niche market without any competitors is the best territory to establish home business. To an extend this perception is true.

Now, you want to include working women in your niche market. In order to do so, you would require leather products exclusively for working women. You can not convince a woman to buy products that are solely for men. In other words, you can not solve a woman's problem with men's products.

o Market your product or service in a manner that will compel your target audience to believe that this is exactly what they need or what they have been looking for. Be prepared to spend time and resource to educate your target audience about your unique product or service. Convince them that only your product or service has the potential to solve their problems forever.

o The last, but the most important niche marketing strategy is to make your target audience believe that your home business is genuine, and not a fragment of an entrepreneur's wild imagination. To achieve credibility, you would have to highlight your home business in all your marketing materials as brochures, websites, press releases and even your business cards.
