Below are some common Client Side Scripting technologies:
- HTML (HyperText Markup Language)
- CSS (Cascading Style Sheets)
Below are the common Server Side Scripting technologies:
- PHP (very common Server Side Scripting language - Linux / Unix based Open Source - free redistribution, usually combines with MySQL database)
- Zend Framework (PHP's Object Oriented Web Application Framework)
- ASP (Microsoft Web Server (IIS) Scripting language)
- ASP.NET (Microsoft's Web Application Framework - successor of ASP)
- ColdFusion (Adobe's Web Application Framework)
- Ruby on Rails (Ruby programming's Web Application Framework - free redistribution)
- Perl (general purpose high-level programming language and Server Side Scripting Language - free redistribution - lost its popularity to PHP)
- Python (general purpose high-level programming language and Server Side Scripting language - free redistribution)
Web Application Frameworks
Web Application Frameworks - Benefits and Advantages
- Program actions and logic are separated from the HTML, CSS and design files. This helps designers (without any programming experience) to be able to edit the interface and make design changes without help from a programmer.
- Builds are based on the module, libraries and tools, allowing programmers to easily share libraries and implement complex functionalities and features in a fast and efficient manner.
- The structure helps produce best practice coding with consistent logic and coding standards, and provides other developers the ability to become familiar with the code in a short time.
Coding Guidelines, Standards & Convention
Important benefits of using Coding Guidelines
- Creates the best environment for multiple programmers to work on the same project
- Provides ease of maintainability and version management
- Delivers better readability and understanding of the source code
- Insures that other developers can understand and become familiar with the code in a short time
Web Applications Lifecycle Model
Some companies follow a certain standard model such as SDLC (System Development Life Cycle) or Agile Software Development Model.
- SDLC is the traditional process of developing software or web applications by including research to identify and define the application requirements, information analysis, architectural design and specifications blueprint, team involvement, programming, testing and bug fixing, system testing, implementation and maintenance.
- Agile Software / Web Application Development is the iterative development process and development process practices that focus on collaboration of people involved and provide a better procedure to allow revisions and evolution of web application requirements. Agile methodology includes research, analysis, project management, design, programming, implementation, frequent testing, adaptation and maintenance.
Web Application Development Process
- Roadmap Document: Defining Web Application, Purpose, Goals and Direction
- Researching and Defining Audience Scope and Security Documents
- Creating Functional Specifications or Feature Summary Document
- Team Collaboration and Project Management Document
- Technology Selection, Technical Specifications, Illustrative Diagram of Web Application Architecture and Structure, Development Methodology, Versions Control, Backups, Upgrades, Expansion and Growth Planning Document, Server Hardware / Software Selection
- Third Party Vendors Analysis and Selection (Merchant Account and Payment Gateway, SSL Certificate, Managed Server / Colocated Server Provider, Fulfillment Centers, Website Visitor Analytics Software, Third Party Checkout Systems, etc.)
- Application Visual Guide, Design Layout, Interface Design, Wire Framing
- Database Structure Design and Web Application Development
- Testing: Quality Assurance, Multiple Browser Compatibility, Security, Performance - Load and Stress Testing, Usability
Web Application Testing
- Quality Assurance and Bug Testing
- Multiple Browser Compatibility
- Application Security
- Performance - Load and Stress Testing
Trends and Popularity
If planned and built correctly, web applications can:
- Reach and service millions of consumers and businesses
- Generate substantial, multi-layer / multi-category income from consumers, businesses and advertisers
- Easily build business goodwill and assets based on audience reach, popularity, technology and potential growth
Below are good reasons for companies to build web applications:
- Companies want to streamline their internal departments and functions, operations, sales and project management, etc.
- Companies want to take advantage of a web based application's flexibility and versatility, by moving away from the traditional desktop application platform to the web application platform
- Companies want to gain more clients or better service their current clients by offering convenient services and solutions online
- Companies want to build new web applications to offer innovative services or solutions to online users and businesses
- There are opportunities to gain the upper hand and bypass the traditional brick and mortar companies when this type of opportunity was rarely possible or existed before the explosion of the web
- The new web created a global business environment which challenges the way in which traditional companies do business
- Companies need to reinvent and evolve in order to compete in today's trends, online business and global marketplace
- Businesses and consumers have more options and resources to research and easily compare and shop around for the best deals
- Information and resources are immense and available to everyone who seeks it
- Businesses or companies who used to profit from consulting or advice, that can now be easily acquired online are struggling, and will need to take a new business direction if they want to stay solvent.
