ANSI/SPARC MODEL

The ANSI/SPARC Model was a joint effort by the American National
Standards Institute and Sun Palo Alto Research Center.  It's 
purpose is to standardize the method for designing databases.
Their method is a three step mapping process that transfers
information from...
1) the realworld, to...
2) a conceptual data model, to...
3) a logical data model, to...
4) a physical data model.

In order to implement the model, we assume that the realworld
has already been mapped to text.  From the text, we map to an
ER Model.  From the ER Model we map to the relational model, 
normalizing the tables where appropriate.  From the normalized 
tables, we use sql to enter the tables into a DBMS.
