Description
Overview:
This homework serves as a refresher and review of basic concepts using an Oracle database. Be sure to
review the reading and complete the tutorials in week 2 prior to completing this assignment
Assignment: Total 100 points
1. Create an Oracle user and assign appropriate privileges for a schema that will support a unique
e-Commerce application.
2. Using PowerPoint, Visio or any graphical tool of your choice, create an Entity Relationship
Diagram showing the entities, relationships and primary keys supporting your e-Commerce
application. Your application should have at least four (4) entities. The total number of
attributes across all entities should be at least fifteen (15). Be sure you use good database
design that includes the use of Primary, Foreign, Not Null, and other constraints.
3. Based on your design, create and describe each of your database tables. The tables must be
created using SQL DDL statements along with all necessary primary key, foreign key and other
integrity constraints. The tables should include comments describing each column that will be
displayed using the appropriate Oracle data dictionary views. Perform both a DESC command to
show the basic data about your tables’ columns, and also perform a SELECT of the data
dictionary to show the comments data you’ve added.
4. Populate your tables with records. The records should represent meaningful data and not
placeholder data. You should populate at least 20 records total across all of your tables.
5. Create one database view showing the combination of at least two tables resulting from a join.
(Hint: Design and test the two-table join first, then create the view using the SQL join you just
created (e.g., create view myView as select … ))
6. Demonstrate your knowledge of select statements by creating at least six (6) queries that will
return different data from your tables and view.
Deliverables:
1. Create a word or PDF document that contains your Entity relationship diagram, table
descriptions, and screen shots of you successfully running all of your SQL statements within
Oracle 12c. The document should be neat, well-organized, well-written and contain minimal
grammar and spelling errors.
2. A .sql script file containing all SQL statements you used for this effort. All SQL statements should
be in one file with appropriate connect statements to differentiate users who run the script. The
script file should contain comments describe each major set of SQL statements. The script
should run perfectly without error when executed from the Oracle SQL*PLUS environment.
