I have mentioned before that I have taken a Spiral approach to teaching the IPT course: that means we have now covered all the topics in the HSC course, but we can now go back to each of the topics and delve into more detail for each one. Today we'll be going back to the Databases topic and looking at an important development in accessing information held in a database: Query By Example. 
  1. Describe the motivation behind QBE's development.  
  2. Identify an example of QBE and explain the ways that it streamlines the process of retrieving data. 
  3. Outline the design principles that QBE demonstrates. 
  4. Compare and contrast QBE with SQL. 
  5. Outline potential ways that QBE could be important to the PRISM program (see yesterday's lesson).
