Software Development Life Cycle

Processes and Quality Management are building blocks for scaleable Web Application Development

Dassnagar Infosystems is a process centric Indian Software Development Company, who builds scaleable custom web applications with future potential to mould into a Portal that offers user friendly navigation, add new features as plug ins and sustain high traffic. Their is one thing common between a Myspace (social network), Youtube (video broadcasting) and tigerdirect.com (B2B Supply chain Portal), they all started as websites and then went on to become successful in terms of traffic and performance other than niche concepts. Portals are not developed overnight, rather they all start as a web site that moulds into a Portal. However this transformation is possible only when the Software was engineered with provisions for scaleability and a strong conceptual model has been put into practice. This makes Software Engineering and Database designing (relational database designing for data concurrency) immensely important and only Software Development Companies with proven SDLC Life-Cyle and quality management framework can offer scaleable solutions. SDLC also ensures that the company has a segregated process control and thus can handle a custom concept by breaking it and dividing in various tiers to finally develop an N-tiered architecture backed by efficient quality assurance checks.

By Definition "Software Development Lifecycle" (SDLC) is a conceptual model used in Project Management that defines stages involved in a software development project and gives better control on the software development process. The most commonly used SDLC models are Linear Sequential Model, Prototyping Model, Rapid Application and Development (RAD) Model, Incremental Model, Win-Win Spiral Model, Concurrent Development Model, Formal Methods Model, Joint application development (JAD), foundation model, build and fix, synchronize and stabilise. Software Development Companies have tailored SDLC Processes to come up with their own custom models propreitory to the organisation. The solidarity of the SDLC methodology is fundamental to growth of a software development company.

Dassnagar Infosystems software engineering division implements a combination of Prototyping and RAD in web application development projects.

Web Application Development Phase (also termed as web development or software programming) : This Process starts once Prototypes are ready and approved by client.
