    3. 3. Software Architecture Styles <ul><li>Examples of Architectural Styles </li></ul><ul><li>There are many common ways of designing computer software components and their communications: </li></ul><ul><li>Blackboard </li></ul><ul><li>Client-server </li></ul><ul><li>Database-centric architecture </li></ul><ul><li>Distributed computing </li></ul><ul><li>Event Driven Architecture </li></ul><ul><li>Peer-to-peer </li></ul><ul><li>Plugin </li></ul><ul><li>Search-oriented architecture </li></ul>

    10. 10. Genres, on the web… <ul><li>… the style and genre issue impacts both the design of the site structure and the information (information design). </li></ul><ul><li>What does a genre communicate? </li></ul><ul><li>Not just the content , but how it can be used, and how the content will be delivered . </li></ul>
    11. 11. Genres on the Internet <ul><li>From physical form to virtual form: </li></ul><ul><li>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 . </li></ul>http:// www.norcalblogs.com/watts/images/newspaper.jpg http://images.huffingtonpost.com/2007-10-25-BloggingheadsonNYT.JPG
