Web Applications

Web Applications

Web Applications

A web application has similar functionality to a regular software application. They use server code to generate webpages that display in a web browser. In the design process, dynamic pages are often mocked-up static pages. They are primarily coded with HTML5, CSS3 and JavaScript just like static pages. Typically, they receive some if not all of the content from a database. Usually they also have additional administrative pages that allow users to update the database. This allows a user that doesn’t have the technical skill needed to create website the ability to update the content in the site. Normally, this ability is provided only for specific users like administrators or registered users.

Applications are usually broken into logical chunks called "tiers", where every tier is assigned a role. Though many variations are possible, the most common structure is the three-tiered application. A web browser is the first tier. The application logic is the middle tier and a database is the third tier. The web browser sends requests to the middle tier, which returns queries or updates the database and may generate a new page.

Single Page Applications

Single Page Applications

A single-page application interacts with the user by dynamically rewriting the current page rather than loading an entirely different page. This approach avoids interruption of the user experience between successive pages making the application behave more like a desktop application. They either load all the necessary code with a single page load, or dynamically load as necessary. Interaction with the single page application often involves dynamic communication with the web server. HTML5 introduced support for applications that can store data locally and continue to function while offline.

Single-page applications aren’t compatible with search engine optimization, they are not the best choice for comsumer sites. In the cases where these applications are consumer products, often a classic model is used for a landing page or marketing site, which provides meta data for the search engine query. Analytics tools such as Google Analytics rely heavily upon entirely new pages loading in the browser. Single Page Applications have a slower first page load than server-based applications. A server-based application just has to push out the required HTML to the browser, reducing the latency and download time. Single-page applications are best used for nonpublic access sites hidden behind authentication.

Responsive web design can be used to make a web application. A conventional website or a single-page application can be made viewable on small screens and work well with touchscreens.

Development Process

 Development Process

We incorporate three development processes. Agile software development, plan-driven development and a hybrid option. The process used depends on the client’s preference. We can structure an agreement based on project requirements and your preference.

Agile software Model

Agile software Model

Agile software development is an approach to software development under which requirements and solutions evolve through the collaborative effort. It advocates adaptive planning, evolutionary development and continual improvement. It encourages rapid and flexible response to change. It breaks work into small increments that minimize the amount of up-front planning and design. These short time frames typically last from one to four weeks.

Accurate estimates, stable plans, and predictions are often hard to get in early stages, and confidence in them is likely to be low. Adaptive methods focus on adapting quickly to changing realities. However, they have difficulty describing what will happen in the future. The further away a date is, the more unclear the outcome. On the other hand, time spent early in the software production cycle can reduce costs at later stages. For example, a problem found in the early stages is cheaper to fix than the same bug found later on in the process. Agile software development can support a number of concrete practices including requirements, design, modeling, coding, testing, planning, risk management, process, quality, etc.

Water Fall

Water Fall

A pure waterfall model is best suited for projects where requirements and the scope are completely defined. It provides a structured approach that progresses linearly in easily understandable and explainable phases. It also provides easily identifiable milestones. It tends to be among the less flexible as the progress flows in one direction through phases. Some common phases are conception, initiation, analysis, design, construction, testing, deployment and maintenance.

A waterfall model, process spends 20–40% developing of planning and writing requirements and specifications with 30–40% of the time to coding, and the rest dedicated to testing and implementation. The project organization is highly structured. A waterfall model places emphasis on documentation such as requirements documents and design documents as well as coding. Documentation can help greatly if team members leave before the project is completed. This can reduce time and cost greatly.

Hybrid Models

Hybrid Models

A Hybrid model mixes element of the agile model and the plan-driven model. Many organizations believe that the agile methodologies are too extreme but need a more flexible plan. Others perceive problems with the "pure" waterfall model, so a modified waterfall models can be adapted.
