Topics Covered

  1. Architecture Overview
    1. Model-Controller-View Pattern (an old story with a new name)
    2. Lots of Controllers
      1. Applying the Controller Pattern
      2. Data Level Controller (Entity Engine)
      3. Logic Level Controller (Service Engine)
      4. Web User Interface Level Controller (Control Servlet, Screen Widget, etc)
    3. The Model goes in the Database
    4. The View is what the user interacts with
    5. Everything else follows from those, and the only trick is to do it efficiently for initial implementation and maintenance.
    6. Data Flow Between Components
      1. Request from Browser
      2. Control Servlet Called
      3. Request Looked Up
      4. Security Checked (encryption, authentication)
      5. Event Called (if defined)
        1. Service Definition Looked Up
        2. Simple Method Called As a Service
          1. Handle Data Coming In
          2. Look Up Information From Database
          3. Save Information to Database
      6. Response Chosen and Called
        1. View Looked Up
        2. Screen (or Region or JPublish page) definition Looked Up
        3. Template Called, Sections Filled In
        4. Data Looked Up (directly through the Entity Engine or through a service)
  2. Configuration & Deployment Overview
