Application Development: Planning, Design, and Deployment

• Application Development refers to the process of planning, designing, and deploying a software application.

Scope of App Dev:

• Planning involves identifying the application's use case and the problems it will solve.
• Analysis includes documenting functional requirements and anticipating challenges.
• Design defines the application's operation and features.
• Construction involves programming the application's features.
• Testing ensures the app and its functionality work as expected.
• Implementation makes the application available to users.
• Support involves continuous monitoring and updating based on user feedback.

Types of Applications:

• Web Applications are accessed via a browser, require internet connectivity, and are served by a server using HTTP/HTTPS protocols.
  • Examples include Google Docs, IAccess, and LSPUOnline.
• Mobile Applications are designed for mobile devices and often can be used offline.
  • Examples include Instagram, TikTok, and Shopee.
• Desktop Applications can be directly downloaded on personal computers or laptops.
  • Examples include Photoshop, Blender, and Office 365.
• Hybrid Applications combine aspects of web and mobile apps, accessible through browsers or direct download.
  • Examples include Twitter, Facebook, and PWAs.

Overview of Emerging Technologies:

• Internet of Things (IoT) involves devices connected via the Internet to communicate with each other.
  • Examples include Smart Fridges and Smart Homes.
• Artificial Intelligence (AI) uses machine learning algorithms to mimic human intelligence.
  • Examples include Chatbots, Speech Recognition, and ChatGPT.
• Augmented Reality (AR) combines the real world environment with digital overlays.
  • An example is Pokemon GO.
• Virtual Reality (VR) provides a fully immersive digital environment.
  • An example is Oculus Rift.
• Blockchain is a decentralized digital ledger allowing for private and encrypted transactions.
  • Examples include Crypto, Bitcoin, and Doge.

Trends in Cross-Platform Development:

• Cross-Platform Development allows development for multiple platforms (iOS, Android, Desktop, macOS, Web) with a single codebase.
• It reduces development time and enhances user experience across devices.
  • Frameworks include Flutter and React Native.
• Increased Focus on User Experience (UX) involves developers focusing on intuitive interfaces and seamless user interaction for increased user satisfaction.
• Integration of AI Features allows applications to integrate AI for a personalized user experience.
  • Examples include Chatbots for Support and Recommendation Systems.
