CATALOG DESCRIPTION
This course is an introduction to business and technical database processing. Emphasis is
placed on the planning, administration, control and design of database systems. Students
will develop applications using a popular DBMS software package. (4.5 lecture hours)
Laboratory fee applies.
COMPUTER CENTER REQUIREMENT
Students should avail themselves of further study and/or educational assistance available in
the Computer Learning Centers located in rooms B-225 and B-116 as part of this course.
These services are to be considered an integral part of the course work and will help the
student master the necessary knowledge and skills for Database Management and
Development.
DISABILITY STATEMENT
If you have a physical, psychological, medical or learning disability that may impact your
ability to carry out assigned coursework, I would urge that you contact the staff in The
Center for Students with Disabilities (CSD) in Building "U", 572-7241, TTY 572-7617.

Characteristics of a DBMS.
Database terminology.
Advantages of the database approach. File-oriented systems compared with database
systems.
File vs. Database Systems.
Data models: Hierachical, Network, Relational, Object-Oriented.
Components of a DBMS
Engine
Data Dictionary

Week 2-3: Systems Design
Systems Design
Feasibility Study
Costs
Benefits
Designing Systems
Identifying User Requirements
Designing Systems with UML
Class Diagrams
Classes & Entities
Associations & Relationships
Class Diagram Details
Data Types
Text
Numbers
Dates and Times
Binary Objects
Computed Values
Week 4: Data Normalization
Normalization
Tables, classes, keys (primary, foreign, candidate, surrogate, composite,
notation)
Dependency
First Normal Form
Second Normal Form
Third Normal Form
concatenated,
Data rules and integrity
Schemas. Semantic rules.
The effects of Business Rules
Documentation of database design
Note: The instructor should give introductory, intermediate, and advanced exercises on
data normalization. The Instructor may use Oracle to demonstrate normalization and
students may complete these exercises using Oracle Database design projects: the student
should be able to take multiple examples of unnormalized data and normalize to 3 NF.
The student should be able to apply these database designs to Oracle by creating the
tables and relating them with rules regarding updates and referential integrity.

Week 5: SQL Queries
Introduction to SQL
Specifying outputs, inputs, table involvement.
Query Essentials: Criteria, Boolean algebra, DeMorgan's Law.
Introduction to SQL.
SELECT statements. SELECT statements with conditions.
WHERE clauses. Computations, Subtotals and GROUP BY. WHERE and
HAVING.
Joining multiple tables.
Note: Students should be given at least 2 introductory, 2 intermediate, and 2 advanced
assignments regarding SQL queries. Oracle may be used to build and perform queries.
Week 6-7: Advanced Queries and Subqueries Using SQL
Advanced SQL Queries
Subqueries of existing queries.
NOT IN, UNION, INTERSECT, EXCEPT.
Defining tables in CREATE.
Data manipulation: INSERT, DELETE, UPDATE.
CASE function, Multiple Joint Columns, Inequality Joins, Cross Tabulation.
Note: Students should be given at least 2 introductory, 2 intermediate, and 2 advanced
assignments regarding SQL queries. Oracle may be used to build and perform queries.
Week 8: Stored Procedures
Purpose/use of stored procedures
Design and implement stored procedures both with and without parameters
Documentation of stored procedures
Note: Students should be given at least 2 introductory, 2 intermediate, and 2 advanced
assignments regarding stored procedures. Oracle may be used to build and run stored
procedures. Documentation should be written with the goal of providing it to “database users”
and should include the purpose of each stored procedure along with any parameters.
Revised Fall 2007
Week 9: Importance of Documentation / Calculations & Data Manipulation
Students should be given an already designed and populated database without any
documentation and be asked to retrieve specific data from that database (using SQL and
already created stored procedures). The student should then be asked to create the
missing documentation for the database and its stored procedures.
Procedural Languages
Programming Environment
Windows Environment
Data On Forms
Data Controls
Control Properties
Using Programs to Retrieve and Save Data in the Database
Building SQL statements with code
Data Aggregation and Computation
ADO objects (ODBC)

Integrity Issues
Deadlock
Lock Manager
Methods of Handling Locks
Note: The instructor may give examples using a computer language on his/her choice (i.e.,
Visual Basic, Java, C++) as long as that language is taught as part of the curriculum in this
department.
