Listen 


iLab Overview 


Beginning with this lab, and continuing through the remaining weeks you will be doing all of your work in the MySQL 

EDUPE Environment. By now you have received your logon ID and password and should have at least made sure 

you can connect. If for any reason you have not done so, please do so now before continuing any further. If for any 

reason you cannot connect, then you need to let the instructor know ASAP so that any problems can be resolved. 

In this lab you will transform a logical database design (data model) into a physical model (tables, constraints, and 

relationships). Your job will be to take the relationship diagram along with the meta data defined in the data dictionary 

and define the table structures and constraints to create the physical tables. Once this has been done, you will 

populate the tables with data. Lastly, you will write SELECT statements to query the tables and verify the data was 

populated.
