physical design and implementation
In this project you will perform the physical design and
implementation using SQL Data Definition Language (DDL) and proceed with populating the Mom and Pop
Johnson Video Store database via Data Manipulation Language (DML) SQL commands.
Each of the steps below requires a SPOOL file to be
submitted. Be sure your SPOOL file
contains your SQL statements along with the Oracle responses and/or displayed
results. Do NOT submit your SQL script
files. Only submit your output SPOOL
files. If you are using iSQL*Plus you
must screen snapshots as necessary of
your SQL and the results.
Project 2 Details:
Create Oracle database tables using SQL Data Definition
Language (DDL) for each table listed in Project 1. Make sure that entity and referential
integrity are enforced by declaring a primary key for each table (these may be
composite keys) and declaring all appropriate foreign keys. Your CREATE TABLE
statements must show integrity constraints, as appropriate, for NOT NULL, UNIQUE,
PRIMARY KEY, FOREIGN KEY, REFERENCES, and CHECK constraints. Be sure to save
your script used to create these tables as yournameproject2step1.sql. You
should test your script to make sure it runs without error. Submit your SPOOL file showing that all SQL
in your SQL script file worked properly.
Provide two examples of SQL DML (i.e., "INSERT")
commands that fail different table integrity constraints you set up in one of
your table. Explain why the statements fail. Be sure to save your script used
to as yournameproject2step2.sql. You can include comments in the SQL script
describing why the insert statements failed.
Submit your SPOOL file showing that all SQL in your SQL script file
worked properly.
Populate each of your tables with at least five valid rows
of data each and show the SQL you used. Populate other tables in your database,
as necessary, to satisfy referential integrity. Be sure to save your script
used to create these records as yournameproject2step3.sql. You should test your
script to make sure it runs without error.
Submit your SPOOL file showing that all SQL in your SQL script file
worked properly.
Write SQL to perform the following queries and updates. Be
sure to save your script used to create these records as yournameproject2step4.sql.
You should test your script to make sure it runs without error:
Retrieve all of your customers' names, account numbers, and
addresses (street and zip code only), sorted by account number.
Retrieve all of the videos rented in the last 30 days and
sort in chronological rental date order.
Produce a list of your distributors and all their
information sorted in order by company name.
Update a customer name to change their maiden names to
married names. You can choose which row to update. Make sure that you use the primary key column
in your WHERE clause to affect only a specific row.
Delete customers from the database. You can choose which row
to delete. Make sure that you use the primary key column in your WHERE clause
to affect only a specific row.
Submit your SPOOL file(s) showing that all SQL in your SQL
script file worked properly. Show the
actual SQL statements executed and the results the SQL produced below the
code. Do NOT submit your SQL script
files. Also, submit all of your .sql files.
Also, Project 1 is attached.
