Easily put, Web Applications are dynamic websites that are paired with server-side software that offers functions like interacting with users as well as connecting to back-end databases and providing results to browsers.
Some examples from Web Applications are Online Banking and social Networking, Online Reservations, eCommerce /Shopping Cart Applications, Interactive Games, Online Training, Online Polls, Blogs, Online Forums, Content Management Systems and more..
There are two major types of coding: scripting and programming for the creation of Web Applications:
I. Client Side Scripting / Coding – Client Side Scripting is the type of code executed or processed by browsers.
Client Side Scripting can generally be accessible to any user of the site (from the menu view, click”View Source”) “View Source” to view the source code).
Below are some of the most common Client Side scripting technologies:
- HTML (HyperText Markup Language)
- CSS (Cascading Style Sheets)
II. Server Side Scripting / Coding – Server Side Scripting is the kind of code that is executed or processed in the browser.
Server Side Scripting isn’t viewable or accessible to any visitors or member of the public at large.
Below are the most popular Server Side Scripting technologies:
- PHP (very popular Server Side Scripting Language – Linux or Unix-based Open Source – free redistribution typically paired together with MySQL database)
- Zend Framework (PHP’s Object Oriented Web Application Framework)
- It is ASP (Microsoft Web Server (IIS) scripting language)
- ASP.NET (Microsoft’s Web Application Framework – the successor to ASP)
- ColdFusion (Adobe’s Web Application Framework)
- Ruby and Rails (Ruby programming’s Web Application Framework – free distribution)
- Perl (general general purpose high-level programming language ) and Server Side Scripting Language – free distribution lost its appeal to PHP)
- Python (general general purpose high-level programming language ) and Server Side Scripting language Redistribution for free)
Program libraries are collections of frequently used functions, subroutines, or classes that offer the ability to develop and maintain your application by allowing developers to include or modify functionalities into an existing frameworked or modular application.
Web Application Frameworks
Web Application Frameworks comprise collections of software libraries, components and tools arranged in an architecture system that allows developers to create and manage complicated web applications using the fastest and most efficient method.
Web Application Frameworks have been designed to simplify programming and encourage reuse of code by establishing the structure and organization of folders as well as guidelines, documentation as well as libraries (reusable codes for classes and functions that are common to all).
Web Application Frameworks – Benefits and Benefits
- The logic and actions of the program are separate from HTML, CSS and design files. This makes it easier for designers (without any experience in programming) to to modify the interface and alter the design without the assistance of programming.
- Builds are based on modules, libraries and tools, which allow developers to use libraries to implement complicated functions and features in a quick and efficient method.
- The structure allows for best practices in coding, with uniform codes and logic and gives other developers with the opportunity to learn it in brief time.
Coding Guidelines, Standards & Convention
Coding guidelines are a set of guidelines and standards that are that are used to program an application for the web.
These standards and rules apply to coding logic, file names and structure as well as file names as well as file organization as well as formatting and indentation statements and classes, and the use of naming conventions. These rules also mandate the writing of clear and concise comments as well as providing documents.
Benefits of the use of Coding Guidelines
- The best setting for programmers from different backgrounds to work on the same project.
- Facilitates maintenance and manages version
- Improves the readability and comprehension of source code
- It ensures that other developers learn and comprehend the code within a short time
Application Lifecycle Model Web Applications Lifecycle Model
Web Application Lifecycle is the procedure of creating an application on the web and the participation of multiple teams involved in the process of development. Each business can define its own distinctive way of working.
Certain companies use a normalized model like SDLC (System Development Lifecycle) as well as Agile Software Development Model.
- SDLC is the standard method of creating web or software applications through using research to identify and establish the application’s requirements information analysis architectural blueprint for design and specifications collaboration with the team programming, testing, fixing bugs systems testing, installation and maintenance.
- Agile Software / Web Application Development is an iterative development method and the development process practices which emphasize collaboration among individuals involved. It also provides the best method to allow modifications and changes to web application specifications. Agile methods include analysis, research planning, design, project management and programming, as well as implementation regular testing, adaptation and maintenance.
Web Application Development Process
Web Application Development Process organizes an effective process and method to application development.
For detail information: Web Application Development Process
The following checklist of processes and documents suggested provide an excellent outline of an Web Application Lifecycle and Process:
- Roadmap Document: Define Web Application, its purpose, Goals, and the direction
- Determining and researching the Security Documents and Scope of Audience
- The process of creating Functional Specifications or A Feature Summary Document
- The Team Collaboration Document and the Project Management document
- Tech Specification Selection Illustration of Web Application Structure and Architecture Development Methodology, Versions Control Backups Upgrades, Expansion, and Growth Plan Document Server Hardware/Software Selection
- Third Party Vendors Analysis and Selection (Merchant Account and Payment Gateway SSL Certificate, Managed Server and Colocated Server provider, fulfillment Centers, Website Visitor Analytics Software, Third Party Checkout Systems and more.)
- Visual Guide for Application, Design Layout, Interface Design Wire Framing
- Designing Database Structures as well Web Application Development
- Tests: Quality Assurance, Multiple Browser Compatibility, Security Performance – Stress and Load Testing Usability
Web Application Testing
Testing is a crucial element in testing as part of the Web Application Development process. In some instances, testing can require more manpower and time than the development process itself.
Here are a few of the most frequently used tests required for any web-based application the development procedure:
- Quality Assurance and Bug Testing
- Multiple Browser Compatibility
- Application Security
- Test of Performance, Loading and stress Testing
Trends and Popularity
Companies are being asked to create Web Applications are growing substantially.
If properly designed and built If designed and built correctly, web-based applications can:
- Service and reach millions of businesses and consumers
- Generate substantialmulti-layer and multi-category revenue from businesses, consumers, and advertising
- Build business reputation and assets based on access, popularity, and the potential for growth
Here are some good reasons for businesses to develop web-based applications:
- Businesses want to simplify their internal departments, processes such as operations, sales, project management, for example.
- Businesses want to make the most of a web-based application’s flexibility and flexibility, shifting away from the traditional desktop-based application platform to Web application platforms
- Companies are looking to increase the number of customers or better serve their existing clients by providing easy solutions and services on the web.
- Companies are looking to develop new web applications that can provide new solutions or services to customers and businesses on the internet.
The web’s applications of today have a significant business implications on how businesses and consumers conduct business. Examples include:
- There are numerous opportunities to gain the upper hand and get rid of the brick and mortar businesses which was not possible or even existed prior to the explosion of the internet.
