Overview
  • WebCT Vista 3.0 contains 4 major areas in the SDK:
    • System Integration
    • WebServices
    • Deployable Components
    • Reporting Interfaces
overview1
Overview
  • Each interface offers access to slightly different parts of the Vista Core Framework
overview2
Overview
  • Each interface also provides a variety of sub-services and ways to get at those services
system integration
System Integration
  • Focuses on enterprise data integration & bulk transactions
  • e.g.:
    • Courses, Sections, Groups
    • Users and Enrolments
    • Bulk file uploads
system integration1
System Integration
  • Broken into 3 layers
    • Transport Layer
    • Translation Layer
    • Core Layer
  • Each layer processes request, then hands it to the next layer
system integration2
System Integration
  • Transport Layer:
    • 3 built-in Adaptors
      • WebAPI
      • Command Line Interface
      • LDIS (SunGard SCT)
    • Option to write your own
system integration3
System Integration
  • Translation Layer:
    • 3 built-in Adaptors
      • IMS
      • LDIS (SunGard SCT)
      • Standard
    • Option to write your own
system integration4
System Integration
  • Core Layer
    • Processes final request and hands actions off to individual Vista services
webservices
WebServices
  • Focus on “user level” transactions
  • Handy for external manipulation/retrieval of user information or course data
webservices1
WebServices
  • Commands are processed by the same services that process UI events
  • Proper permissions apply
    • e.g.: Student cannot edit Quiz
webservices2
WebServices
  • Supported Interfaces in Vista 3:
    • Context
    • Calendar
    • Gradebook
    • Mail
    • File Manager
    • Quiz & Question

documentation
Documentation
  • Full Web Services Javadoc included in SDK Client Distribution
  • SDK Programmer’s Guide covers best-practices and higher-level documentation
webservices3
WebServices
  • Example Applications:
    • Remote mail client
    • Portal integration
    • Remote quiz delivery
    • File uploader
slide25

Deployable Components

  • Added in Vista 2.1
  • Focused on:
    • Authentication of users into/from Vista
    • Delivering content and applications to Vista frameset
deployable components
Deployable Components

Deployable Components

  • Authentication Modules (AuthModules for short) enable SSO into Vista
  • Format of SSO is up to you; Vista only supplies the framework
  • Great for Portals
slide27

Deployable Components

  • Proxy Tools do the opposite, allowing users to be brought from Vista to another application
  • They allow an AuthModule to appear in the UI just like any other tool (Quiz, Mail, etc.)

Deployable Components

  • In Vista 2.1, an XML file was used to create Proxy Tools. Vista 3.0 introduced a very nice, and easy to use UI

reporting
Reporting
  • WebCT contains vast amounts of data
  • Prior to WebCT Vista, this data was stored in a distributed, flat file database
  • This made correlation and detailed data analysis almost impossible
reporting1
Reporting
  • WebCT Vista introduced an SQL database server
  • With that, detailed analysis became possible, but there was still a problem
reporting2
Reporting
  • The Vista data schema is not exactly intuitive
  • The DB is designed for functionality and performance, not for data extraction
  • Relevant information can be spread out among many, many tables
  • The table schema can change from version to version
reporting3
Reporting
  • The Vista Reporting Interfaces solve these problems by abstracting away from direct DB access
  • The result is a set of “safe” database views containing the most relevant data all in one place
