Why Learn Databases?
STORE INFORMATION
 Information is a valuable commodity
 Information is used for marketing and BI
(Business Information)
 Used by all kinds of businesses
 Access to good information (if properly done)


Market to individuals creatively, rather than “mass
mailing”,

more customized (Business Intelligence)

Database Terms

DATA
◦ From dictionary.reference.com, “INDIVIDUAL
facts, statistics, or items of information”.
◦ NEVER “CONTRIVED” OR “DERIVED”

Database Terms

DATASET

According to Dictionary.com, a database is “a
comprehensive collection of related data organized
for convenient access, generally in a computer.”
usually refers to data selected and arranged in rows
and columns

◦ for processing by statistical software. The data might have
come from a database, but it might not have.

Simply put, an: “ORGANIZED COLLECTION OF
DATA.”

DATABASE
◦ A COMPREHENSIVE collection of RELATED data
organized for convenient access
A database is usually under the control of a
DATABASE MANAGEMENT SYSTEM, which is
software that, among other things, manages
MULTI-USER ACCESS to the database.
(“usually”, but not necessarily. )

Database Terms

DATABASE MANAGEMENT SYSTEM
(DBMS)
Provides TOOLS needed to organize data in
a flexible manner. It includes:

 facilities to ADD, MODIFY or DELETE data
 Never DELETE, instead flag the data as REDUNDANT.
 ask questions (queries) about the data stored
 produce reports
9
BENEFITS:

They are able to STORE LARGE AMOUNTS OF
DATA and SORT it according to your needs.
Also, having information SAVED ON A COMPUTER
rather than written on something will help with the
chances of NOT LOSING the
 information.


Ability to SHARE the information

Ability for MORE THAN ONE PERSON to work on it

Fewer inconsistencies in data / reduces redundancies10

Database MODELS
According to Wikipedia: A database model is
the THEORETICAL foundation of a database
and fundamentally determines in which
manner data can be stored, organized, and
manipulated in a database system. It thereby
defines the infrastructure offered by a
particular database system.

Simply put, a database model determines
HOW data is STORED and ORGANIZED
13
Database Model – Relational
RELATIONAL database model is the
most common
 Composed of tables, each constructed
like a flat file
Click here to open an Excel file which
illustrates Flat files

14
What are Tables or Entities?

TABLES (aka “ENTITIES”) in the relational model
are used to represent "things" in the real world.

ENTITIES are made up of ROWS and Columns.
 Columns are called fields or attributes.
 ROWS are called RECORD

Within a table, each ROWS is called a RECORD
and it represents 1 particular instance of its entity,
not unlike the flat file.
15
What is a Primary Key?
A FIELD in the database that guarantees
UNIQUENESS
 SPEEDS data RETRIEVAL

Each RECORD in a table must have a
PRIMARY KEY
 Each PRIMARY KEY is the 1ST attribute
(column) listed

16
What are Foreign Keys?
A FOREIGN KEY is used to indicate a
relationship between 2 or more TABLES
 Each FOREIGN KEY is a PRIMARY key in another table

• BE CAREFUL when you are DOWNLOADING your assignment
files. When you DOWNLOAD them, the files come with an
embedded ENCRYPTION code
• IF you COPY THE FILE from another student, your assignment will be
flagged with a “POTENTIAL INTEGRITY VIOLATION”,(cheating).
• EVEN IF YOU SEND AN UNedited file, you may be legitimately
doing your own work, but, the file has the ENCRYPTION code
• your assignment will be flagged with a “POTENTIAL INTEGRITY
VIOLATION”,(cheating).
23
ASSIGNMENTS-BE CAREFUL WHEN
DOWNLOADING
“CHEATING” possibilities
• You have to be very, very careful with ALL the components in
myitlab. The software is extremely specific—it IS case-sensitive, and
if you add a space where there shouldn’t be (or vice versa), or forget
to include a punctuation mark (or vice versa), myitlab will mark it
wrong.
• When you do your assignments, you must read the instructions
extremely carefully, not “skimming over” any of the instructions, just
in case you miss a tiny requirement.
24
ASSIGNMENTS—READ
INSTRUCTIONS VERY, VERY
CAREFULLY!!
PRINT OUT ASSIGNMENT MARKS
Please make sure that as soon as you get your MARK for ANY assignment,
that you do the following:
1.
2.
3.
4.
5.
Hit your PRINT SCREEN button on your keyboard
Open MS WORD
PASTE
Enlarge the “screen capture”, so that it’s readable
PRINT out your MARK, AND SAVE the file to the DESKTOP
-then UPLOAD the file to SkyDrive
6.
You may now close the dialog box.
There have been some students who have gotten their mark, but
when they close the dialog box with the mark on it-- they receive a “0” in their
GRADEBOOK. (This is the mark that I see). This “print out” will be your backup
copy—put it in a safe place, until the end of the semester.
25
DO NOT CLOSE the dialog box with your mark on it--before doing the
following:
SUBMITTING ASSIGNMENTS:
3 STEPS
1.Click on: “Upload Completed Assignment”
2.Navigate to where your completed
assignment file is, double-click on the file,
and then click on:
“Upload”
26
3. IMPORTANT: THEN CLICK ON:
“FINISH: Submit for Grading”
4. AFTER submitting assignment, there is a
“TIME LAPSE”
You can view results by clicking on the chevron
beside the specific assignment, and select:
“VIEW SUBMISSIONS”
27
Will give 3 files:
1. SUBMITTED FILE
2.SUMMARY
REPORT
3. MARKED UP REPORT
1. SUBMITTED FILE
Opens a .zip file which is a
COPY of the file you
submitted for your
assignment
28

• click on the arrow to EXPAND the information, to
find out exactly where you
went wrong.
