Database refresher by Ullas in Tuesday's class

[Subbarao Kambhampati <rao@asu.edu>]

Folks:

According to the survey about your saturday availability,   8/18 were 
available this saturday; 13/18 were available on 3rd April and 12/18 on 
24th. So, I went with plan C--> which involves using Tuesday class for 
database refresher; and keeping the option of  a separate extra class later 
in the semester open.

So, here is the plan for  Tuesday.

On Tuesday, there will be a regular class meeting--where Ullas Nambiar will 
do a recitation/refresher on Databases (specifically, the part of the 
databases that everyone needs to know to go about effectively for the rest 
of the course). The slides will be drawn from

http://rakaposhi.eas.asu.edu/cse494/notes/rao-db-1.ppt

He will discuss the ideas of "schema", "tables with attributes as rows and 
tuples as columns"; table/relatioanl operations
(projection, selection and join queries), a quick overview of SQL as a 
query language for databases.

This may be sort of a "refresher/repeat" for people who took a full 
database course already--but in the past, students appreciated a quick 
one-class overview. So, I would encourage all of you to attend.

----
On Thursday, I will assume that you know db concepts and start off with 
issues brought up by the presence of DBs on the web (ullas may bring up 
some of this by way of motivation too).
