  • Architectural Styles
    • In software architecture, a style is a set of design rules that identify:
      • The kinds of components and
      • The relationships & communications between components that form the system.
    • Choose a style based on the purpose, the type of task or the type of problem .
  • Software Architecture Styles
    • Examples of Architectural Styles
    • There are many common ways of designing computer software components and their communications:
    • Blackboard
    • Client-server

  • Blackboard Architectural Style
    • Three Major Components:
    • The Knowledge Sources (KS) are modules that provide specific expertise needed by the application.
    • The blackboard, a shared workspace and dynamic "library" of contributions to the current problem
    • The control shell, which controls the flow of problem-solving activity in the system.
    Useful for brainstorming style of interactions between diverse users www.piffe.com ww.physics.utoronto.ca/.../blackboard.jpg View slide
  • “ Peer to Peer” Architectural Style
    • A peer-to-peer (P2P) style:
    • Network formed by diversely connected participants
    • Relies on the cumulative bandwidth of network participants rather than centralized resources
    • Useful for file-sharing- e.g. Napster, Limewire
    Server-Based Network Peer-to-peer Network
  • Information Architecture… Genres
    • In the context of the web, there’s a similar need to identify the style of the information architecture.
    • In IA, have the emergent idea of Genres , “metadata genres” or “document genres”
    • Genres help to identify the content and how it will be used.
  • Genres…
    • What are common genres in print media ?
      • Newsletters, newspapers, flyers, brochures, guidebooks, encyclopedias, coffee-table art books, the grant proposal, reports, legal briefs, others?
    • Common genres in film and video ?
      • Documentaries, broadcast news, romantic comedies, film noir, others?
  • Definition: Genres
    • Orlikowski and Yates*:
    • A genre is "a distinctive type of communicative action ,
    • characterized by:
      • a socially recognized communicative purpose &
      • a common aspects of form" .
    *JoAnne Yates and Wanda J. Orlikowski, "Genres of Organizational Communication: A Structurational Approach to Studying Communication and Media, Academy of Management Review, 17 (April 1992), 299-326.
  • Definition: Genres
    • Genres emerge as a response to a purpose :
    • the advertising brochure emerged as a genre because of a need to quickly and easily distribute information about businesses and services.
  • Genres, on the web…
    • … the style and genre issue impacts both the design of the site structure and the information (information design).
    • What does a genre communicate?
    • Not just the content , but how it can be used, and how the content will be delivered .
  • Genres on the Internet
    • From physical form to virtual form:
    • On the web, we don’t have physical forms that give us cues about genres. So we have to convey the genre through the information design and site structure .

  • Let’s look at some sites
    • What is the genre?
    • New, internet-specific genres: search engines, the search page
  • Different kinds of sites:
    • MOMA is different from Fresh Direct, why?
  • Or PC vs Mac?
    • Genres also convey a narrative . Does the Apple site represent a genre? What is its narrative?

  • Real world architecture:
    • The Government Office Genre
    • The White House: what does this structure convey about the contents, the function?
  • Real world architecture:
    • Compared to Mayor Bloomberg's office:
    • What does this style say about his site, his company, and the way he governs the city?
