Beginning with this lab, and continuing through the remaining weeks you will be doing all of
your work in Oracle itself. The editor interface to the Oracle server is SQL*Plus, and 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.
Before attempting Lab #3, you need to be sure you have read through the SQL*Plus
tutorial which can be found in Doc Sharing as well as under the SQL*Plus Tutorial tab in Week
3. This tutorial describes the functionality of the editor and will take you through the process of
setting up and using the SQL*Plus in the iLab environment so that it will best serve your needs
for the remainder of the labs required for this course.
The lab for this week addresses taking a logical database design (data model) and now
transforming that into a physical model (tables, constraints, and relationships). As part of the lab,
you will need to download the Zip file titled "Lab 3 Support Documents" from Doc Sharing.
This Zip file contains three documents: Lab 3 Relationship Diagram.docx, Lab 3 Meta Data
Diagram.xlsx, and Lab 3 Input Data.docx.
Your job will be to take the meta data defined in the data dictionary spreadsheet document, and
using the relationship diagram as a guide define the table structures and constraints using both
CREATE TABLE and ALTER TABLE statements. Once this has been done, you will need to
write the INSERT INTO TABLE statements to insert the data provided into the table. The data
should verify that the constraints you have created are valid and define the correct referential and
data integrity constraints asked for. Lastly, you will write SELECT statements to query the tables
and verify the data was populated.
Narrative/Case Study
For this lab, you be working with command-line SQL to build a series of relational tables, using
SQL CREATE statements in a script file format for the Student Database and then populate
those tables through the use of INSERT statements with sample data.
You will need to create a script file and name it YourName_Lab3.txt containing the following
code:
1. The drop table statements listed later in the specifications of this lab.
2. The CREATE TABLE statements required to build the seven (7) tables.

2. 3. The INSERT statements necessary to insert all of the sample data.
4. Seven select statements to verify that the data is in the tables and accessible.
To help you accomplish this task successfully, you are being supplied with the following three
documents which can be found in the Doc Sharing tab on the course website:
1. A Relationship Diagram of the database showing in graphical form the 1:M relationships
between the tables (336_Lab3_Relationship_Diagram.doc).
2. A Meta Data chart providing information about table names, column names, etc. Be sure
to follow this reference exactly when constructing your CREATE TABLE statements
(336_Lab3_Data_Dict.xls).
3. A listing of sample data to use when writing the INSERT statements to populate the
tables (336_lab3_input_data.doc).
The following guidelines are being provided to help assist you in creating your script file:
• Create the tables in the order shown in the data dictionary. Use the names for the tables
and columns as listed in the Meta Data chart – Do not change them as it will affect your
grade.
• Creating CONTRAINTS -
• Create all constraints as indicated in the data dictionary.
• Constraint suffixes must be as follows:
• Primary key constraint – PK
• Foreign key constraint – FK
• Check constraint - CC
Explicitly name all constraints PRIMARY KEY, FOREIGN KEY, and CHECK constraints to
reflect:
• TableName_ColumnName_ConstraintSuffix (For example, to name a PRIMARY KEY
constraint on the SID column in the student table you would use STUDENT_SID_PK.)
• For this lab you do not have to explicitly name NOT NULL constraints
Create all PRIMARY KEY and NOT NULL constraints within the CREATE TABLE statements
at the column level (line level), unless the Primary Key is a composite Primary Key (yes, there is
one). Composite Primary Key constraints must be created at the table level. Create all FOREIGN
KEY and CHECK constraints at the table level using ALTER TABLE statements. All constraints
must be added prior to populating the tables with data. Create all of the tables and all of the
constraints before populating any of the tables with data. Insert statements must be in the same
order as the tables are created (follow the order in the sample data file). ALL character strings

3. must be enclosed in single quotes. This includes alpha strings and alphanumeric (remember that
any formatting within a numeric strings makes it alphanumeric). If you are inserting a NULL, do
not enclose the word NULL in single quotes, as this will insert the word NULL into the row. To
insert a null you simply use the word NULL.
Deliverables
The deliverable for this lab will include the following documents.
1. Your script file. Create this file in Notepad not Word. Make sure your name is in a
comment area at the top of the script file. Use a double dash to create a one line
comment:
--Jacob Smith
--Lab 3
1. Your lab output file created using a spool session in SQL*Plus.
Be sure to use the SET ECHO ON session command when creating the output file so that both
the SQL commands and results will show in the output. Be sure your name is on all documents
and that all documents have been included in a single Zip file for this week’s assignments.
LABSTEPS
STEP 1: The DROP statements
The following DROP TABLE statements must appear at the top of your script file. This will
allow you to run and re-run your script file as often as you need to. The first time you run your
script file you will get an ERROR on the drop statements saying the Table or View does not
exist. This is true since it has not been created yet, but the error is more informational than
anything. Once the tables are created, you will not get this error again.
DROP TABLE ENROLLMENT CASCADE CONSTRAINTS PURGE;
DROP TABLE COURSE_SECTION CASCADE CONSTRAINTS PURGE;
DROP TABLE COURSE CASCADE CONSTRAINTS PURGE;
DROP TABLE TERM CASCADE CONSTRAINTS PURGE;
DROP TABLE STUDENT CASCADE CONSTRAINTS PURGE;
DROP TABLE FACULTY CASCADE CONSTRAINTS PURGE;
DROP TABLE LOCATION CASCADE CONSTRAINTS PURGE;
STEP 2: The CREATE TABLE statements

4. Next, define the CREATE TABLE statements for the seven tables that you are to create based
upon the ERD and Data Dictionary that you have been given for this lab. Be sure to follow the
guidelines given above on how and where to create the different types of constraints for each
table.
STEP 3: The INSERT statements for the data
The third step is to create the insert statements to insert the sample data into the tables created in
Step 2. You might find it helpful to take the Word document containing the sample data and save
it as a text file. After doing this, you could create the insert statements around the actual data that
is in that file. The process for doing this should have been covered in one of the lectures for this
unit. If it was not, then ask your instructor to discuss this process with the class.
STEP 4: The SELECT statements
The next step of the lab will be to create the select statements to verify the data was inserted
correctly. You should have seven select statements; one for each table. The command is
SELECT * FROM Table_Name; For example, to select all columns from the Student table, the
command would be SELECT * FROM Student;
Be sure to save all of the above statements in your script file.
STEP 5: Testing and verifying your script
Now we come to the point of verifying that your script file works by creating all of the tables and
inserting all of the data. To verify this you will need to execute your saved script file and create
an output file to capture the results being returned to the session by using the spool COMMAND
outlined in the tutorial "Using Oracle SQL*Plus." This output file will be one of the files you
will be turning in for grading.
