Content:

This lecture is an introduction to eXtensible Markup Lanaguage. Today we cover the syntax of XML, some example applications, and look at demonstration programs using .Net classes that support the reading, writing, and manipulation of XML.
  1. The Syllabus describes topics to be covered, reading material for you to digest before coming to class, and due dates for the assigned projects.

  2. Friday Help Session:

    • This week's Help Session will be held in LSB 001 - the large auditorium where we held our grad orientation in August. Time is from 4:00pm to 6:00pm, Friday September 30.
    • After this week the Help Sessions will revert to the 9:00am venue in CST 4-201.

  3. Project Helpers:

    Project #1, Project #2
    Code from Visual Studio Help Session last Friday - new version of Project2Starter
    Find Visual Studio Command Window used to test Compile.bat and Run.bat files

    We will spend some time discussing Project #2, specifically material added to the noSQL Blog.
    The focus of this discussion will be:
    • Design and implementation for Query processing - LambdaDemo will be especially useful.
    • Sharding
    • ElementFactory - just a few comments here.
    • Timer demo - useful for Persistance scheduling.
