Instructional Philosophy
• Out-Come based education
• Would rather discuss than lecture
– Requires student preparation
• Hate grading assignments
– Especially LATE assignments
• Use class interaction, assignments,
quizzes and projects to determine if
outcomes are met.

COS 346 Survival Primer
• Read Material BEFORE the class discussion
• Check WebCT Often
• Use the additional resources identified in syllabus
• ASK questions about what you didn’t understand in
readings
• DON’T do assignments and projects at last minute.
• REVEIW lectures and notes
• Seek HELP if you are having difficulties
• OFFER feedback and suggestions to the instructor in a
constructive manner

The Characteristics of Databases
• The purpose of a database is to help people
track things of interest to them
• Data is stored in tables, which have rows and
columns like a spreadsheet. A database may
have multiple tables, where each table stores
data about a different thing
• Each row in a table stores data about an
occurrence or instance of the thing of interest
• A database stores data and relationships

Naming Conventions in this Textbook
• Table Names are written with all capital
letters:
– STUDENT, CLASS, GRADE
• Column names are written with an initial
capital letter, and compound names are
written with a capital letter on each word:
– Term, Section, ClassNumber, StudentName

Databases Create Information
• Data = Recorded facts and figures
• Information = Knowledge derived from
data
• Databases record data, but they do so in
such a way that we can produce
information from the data
– The data on STUDENTs, CLASSes and
GRADEs could produce information about
each student’s GPA

Components of a Database
System: Microsoft Access

1-18
Microsoft Access
• Microsoft Access is a low-end product intended
for individual users and small workgroups
• MS Access tries to hide much of the underlying
database technology from the user
• A good strategy for beginners, but not for
database professionals
• NOTE: MS Access is discussed in detail in
Appendix A

Example SQL
SELECT StudentNames, EmailAddress
FROM STUDENT
Where StudentNumber > 200
If Exists
( SELECT *
FROM SYSOBJECTS
WHERE [Name] = ‘CLASS’
AND type = ‘U’)
DROP TABLE CLASS

Applications, the DBMS and SQL
• Applications are the computer programs
that users work with
• The Database Management System
(DBMS) creates, processes and
administers databases
• Structured Query Language (SQL) is an
internationally recognized standard
database language that is used by all
commercial DBMSs

1-22
What Is MS Access?
• MS Access is a DBMS plus an application
generator:
– DBMS creates, processes and administers MS
Access databases
– The application generator includes query, form and
report components
• The MS Access DBMS engine is called Jet,
which is not sold as a separate product
• MS Access 2000 and later can be used as an
application generator for the MS SQL Server
DBMS

The Database
• A database is a self-describing collection
of integrated tables
• The tables are called integrated because
they store data about the relationships
between the rows of data
• A database is called self-describing
because it stores a description of itself
• The self-describing data are called
metadata, which is data about data
