Architecture and Technologies

Architecture

  • iAd has a modular design where presentation (what the user sees), Business Logic and Data (where advert data etc. are stored) are separated into different tiers
  • This is reflected by the use of a well known design pattern for web applications called the Model-View-Controller (MVC) which forms the basic architecture of iAd
    • MVC organizes an interactive application into three separate modules:
      • one for the application model with its data representation and business logic
      • the second for views that provide data presentation and user input
      • the third for a controller to dispatch requests and control flow
