This file describes the contents of the KATZENJAMMER 
dataset developed for the CPE 365, Introduction to 
Databases, course at Cal Poly.

The database contains information about the musical 
career of a pop band Kaztenjammer from Norway. The
band consists of four members, each of whom sings and
plays a variety of instruments. The dataset details each
band member's contribution to each song recorded and
performed by the band.


General Conventions.

 1. All files in the dataset are CSV (comma-separated values) files.
 2. First line of each file provides the names of
    columns. Second line may be empty, or may contain
    the first row of the data.
 3. All string values are enclosed in single quotes (')


  The dataset consists of the following files:

       Albums.csv: the list of albums recorded by Katzenjammer
         Band.csv: the list of members of Katzenjammer
  Instruments.csv: instruments the band members play on each song
