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.

The major software development life cycle models are-

  • Waterfall Model
  • Iterative Model
  • Spiral Model
  • V-Model
  • Big Bang Model

Other related models are Rapid Application Development (RAD), Prototype and Agile Models.

The advantages of choosing an appropriate Software Development Life Cycle (SDLC)-

  • Increased Product Quality
  • Increased Development Speed
  • Improved Client Relations
  • Improved Tracking & Control
  • Decreased Project Risks
  • Decreased Project Management Overhead

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.

Performing a Public Records Search For Ohio

With one of the largest universities in the world and an incredible amount of diversity, Ohio is a wonderful place to live and a great place to request vital records. The founding fathers here understand how important it is to keep government open and honest and the laws on the books here are aimed at keeping things that way. According to state law, records requests have to be filled in a reasonable period of time and the requesting party can determine the medium in which records are delivered.

There is also strict word in the law that helps to keep costs down so that everyone can request copies of vital records. According to the state website, vital records cost $ 16.50 per copy and can be sent anywhere in the United States. All records requests in the state of Ohio go through the capital in Columbus. Corporate trademark records, sales tax records, hunting and fishing license records and more are all located in the state capital, which is also the location for Ohio State University.

Currently, there is no state-managed online database governing vital records in Ohio. Much has been made recently in the state media about the creation of such a database since other states have had them up and running for years. With Ohio's population of over 11 and a half million people, it is understandable why such a database has not been put online, but once it is, ordering records from the Buckeye State will be easier than ever.

You can still retrieve a record online from the state of Ohio when you use Records Project. Tap into the most powerful public records database on the Internet when you use the Records Project to locate and order the public records you need. Do not go another day without the records you need to make your life complete; order today

Construction Engineering Jobs Are Critical In A Building Boom

With the recent decline in home sales and the increase in foreclosures, we are poised for yet another change. New home sales are predicted to be back on the rise in the coming years and with the increase in new home sales will come an increase in construction engineering jobs. New construction will again take hold as soon as home prices are said not to go any lower. This leaves room for the prices to go nowhere but up.

Anytime you have new homes being built you will have construction engineering jobs being created. Over the last couple of years, many people got out of the industry as many companies were losing bids and jobs they had previously held. One company, for example, would routinely build hundreds of homes per year. However, when the housing crisis hit they went from hundreds to only building 10 homes in 2010. This of course left them to the only course of action to save their business and that was to lay off over 80% of their staff.

When these layoffs occur, you have many people out of work. When you have people from the construction industry out of work, they typically try to stay within the industry somehow. Therefore, what you end up with is possibly a construction engineer job being taken by a person who used to manage a job site. In addition, you will have a site electricians position being applied for by a plumber. It is not uncommon for people to switch trades when jobs are scarce.

When the economy is in trouble, people scramble. During this period, we had many people learn new trades and are now able to fit into multiple positions within the industry. Estimates now have the economy being revived in the next 3 years. In this period, we will see many new homes being built and this will result in new jobs being created. Some of these new jobs may be filled by people who are new to the industry while some will be filled by people who worked in the construction industry before the crisis and have since just changed the job they do.

Construction engineering jobs pay very well. In addition, any job that pays well will usually require some time spent in school. These are not jobs that just anybody can do. They require training and technical expertise. With all the layoffs over the last couple of years, many people went back to school. There were a percentage of people who had money saved and were able to take the time during their layoff to go to school. In addition, those who did and wanted to remain in the construction industry would have been smart to go into construction engineering. The amount of jobs available to a person with that training under their belt is almost triple what would have been available to them before going to school.

Therefore, with the housing crisis now estimated to be over within the next year or two many people will eventually be getting back to work. With new home sales comes new home construction and that brings jobs. Many who were out of work in the past will soon be able to return to work. If they were once in the construction industry, they may now have a chance to return to work as jobs in that industry will soon be on the rise. There will be many construction engineering jobs available to those who have the knowledge and training. Many people over the last couple of years have sought to gain that education and are now ready to put it to work.
