APPLYING AUTO-FILTER ON ONE AND
MULTIPLE COLUMNS
 By filtering information in a worksheet, you can find values
quickly.
 You can filter on one or more columns of data.
With filtering, you can control not only what you want to see,
but what you want to exclude.
 You can filter based on choices you make from a list, or you
can create specific filters to focus on exactly the data that you
want to see.
95
 When you filter data, entire rows are hidden if values in one or
more columns don't meet the filtering criteria.

DATA VALIDATION
(KENDRA & MCINTOSH ONLY)
It is used to control the type of data or the values that users enter into a
cell.
Data validation options are located on the Data tab, in the Data
Tools group.
You configure data validation
in the Data Validation dialog box.
DATA VALIDATION
When is data validation useful?
Restrict numbers outside a specified range For example, you can
specify a minimum limit of deductions to two times the number of children in a
particular cell.
Restrict dates outside a certain time frame For example, you can specify
a time frame between today's date and 3 days from today's date.
Restrict times outside a certain time frame For example, you can
specify a time frame for serving breakfast between the time when the
restaurant opens and 5 hours after the restaurant opens.
Limit the number of text characters For example, you can limit the
allowed text in a cell to 10 or fewer characters. Similarly, you can set the
specific length for a full name field (C1) to be the current length of a first
name field (A1) and a last name field (B1), plus 10 characters.
Validate data based on formulas or values in other cells For example,
you can use data validation to set a maximum limit for commissions and
bonuses of $3,600, based on the overall projected payroll value. If users
enter more than $3,600 in the cell, they see a validation message.
DATA VALIDATION
Data validation messages:
CON
TYPE
USE TO
Stop
Prevent users from entering
invalid data in a cell. A Stop alert
message has two options:
Retry or Cancel.
Warning
Warn users that the data they
entered is invalid, without
preventing them from entering it.
When a Warning alert message
appears, users can click Yes to
accept the invalid entry,No to edit
the invalid entry, or Cancel to
remove the invalid entry.
Information
Inform users that the data they
entered is invalid, without
preventing them from entering it.
This type of error alert is the most
flexible. When
an Information alert message
appears, users can click OK to
accept the invalid value
or Cancel to reject it.
PROTECTING WORKSHEETS
(KENDRA & MCINTOSH ONLY)
 By default, all cells in an Excel spreadsheet are locked. This
makes it very easy to protect all data in a single worksheet
simply by applying the Protect Sheet option.
 Unlocking specific cells permits changes to be made to these
cells after the protect sheet option has been applied.
 Often certain areas of a worksheet are unlocked so that new
data can be added. Cells containing formulas, functions, or
other important data are kept locked so that once the protect
sheet option has been applied, these cells cannot be changed.
PROTECTING WORKSHEETS
Protect a worksheet in Excel
1.
Open an Excel file to protect. If you open a new file all cells in the worksheet
will be protected. If you wish, follow the example in step one to unlock certain
cells in a worksheet.
2.
Click on the Home tab.
3.
Choose the Format option on the ribbon to open the drop down list.
4.
Click on Protect Sheet option at the bottom of the list to open the Protect
Sheet dialog box.
5.
This dialog box contains a number of options when protecting the worksheet.
6.
The first option is to add a password to prevent worksheet protection from
being turned off. This password does not stop users from opening the
worksheet and viewing the contents.
PROTECTING WORKSHEETS
7.
Next there a number of options that can be turned on or off with
check boxes. The first two allow a user to drag select locked and
unlocked cells. If these two are turned off, users will not be able to
make any changes to a worksheet - even if it contains unlocked
cells.
8.
The remaining options allow users to carry out specific tasks on a
protected worksheet, such as formatting cells and sorting data.
9.
These options, however, do not all work the same. For instance, if
the format cells option is checked off when a sheet is protected, all
cells can be formatted. The sort option, on the other hand, works
only on those cells that have been unlocked before the sheet was
protected.
10. When you have selected the appropriate options, click OK.

DATABASE DESIGN
Basic Terminology:
A table consists of data that is arrayed in rows and columns.
A row of data is called a record.
A column of data is called a field.
Thus, a record is a set of related fields. The fields in a table
152
should be related to one another in some way.
BASIC TERMINOLOGY
Primary key field is a field in which each record has a
unique value.
e.g. The SSN
Compound Primary Key is used when there is no single
field whose values are all different. In that case, two or more
fields are combined. The combination of the fields’ values
should be unique.
Foreign key is the primary key of another table.
e.g. suppose we need to link the employee table with
the
Hours worked table for payroll purposes. The Employee ID
number (EIN) is the primary key of the employees table but the
foreign key of the hours worked table.
153
*Every foreign key must be associated with a primary key in
another table.
BASIC TERMINOLOGY
A form is a database object that is created
from an existing table to make the process
of entering data more user-friendly
A query is the database equivalent of a
question that is posed about data in a table
(or tables).
154
Queries can be designed to search multiple
tables but these tables should be
connected by a join operation.
DATABASE DESIGN
Database design concepts:
Entities an entity is a tangible thing or an event. It is a person, place,
thing or concept about which data can be collected.
Consider the following examples:
1)
The database of a video store would have one entity named video
and another named customer (These are physical entities).
2)
Organizations incur expenses from paying hourly employees and
purchasing materials from suppliers. Hours worked and purchases
are event entities in the database of most organizations.
3)
The library lends books for free. If you were to think of checking
out a book as a sales transaction for zero revenue, how would you
handle the revenue generating event?
155
The event entity here is the number of checkouts.
DATABASE DESIGN
Relationships you should consider the relationship of each entity to the
other entities you have identified.
Cardinality of any relationship can be one-to-one, one-to-many, or many-tomany.
A one-to-one relationship is like A book is published by one company or A
shark lives in one place (the ocean).
There is a many-to-many relationship between the records in the doctor
table and records in the patient table because doctors have many patients,
and a patient could have several doctors;
156
A one-to-many relation between the department table and the doctor table
because each doctor may work for only one department, but one department
could have many doctors.
DATABASE DESIGN
A book can have more than one author. An author can write
more than one book. How would you describe the
relationship between authors and books?
Many-to-many
A member can borrow any number of books at one checkout.
A book can be checked out more than once. How would you
describe the relationship between books and checkouts?
157
Many-to-many
DATABASE DESIGN
Attributes an attribute is a characteristic of an entity. These
attributes become the table’s field.
E.g. what are the attributes for the entity “Customer”?
Customer ID, First name, Surname, Date of Birth, Address
and Phone no.
What are the attributes for the entity “Fashion Model”?
158
Name, Height, Weight, Dress size, Hair color and Eye color.
DATABASE DESIGN
RULES
Rule 1: You do not need a table for the business
The database represents the entire business. Thus in the
practice example* The library is not an entity.
*practice problem at the end of tutorial A.
Rule 2: Identify the entities in the business description
159
In our example the entities are Members, employees and
books.
DATABASE DESIGN
RULES
Rule 3: Look for relationships among the entities
look for relationships between entities; one-to-many and
many-to-many.
In our example: one-to-many: a member can check out more
than one book.
Rule 4: Look for attributes of each entity and designate a
primary key.
Primary Key
Attributes of members: name, DOB, phone no., email
address, member ID card number …etc.
Employees: name, # of hours worked, job title,…etc.
Foreign key
160
Books: name, authors, type, status, member ID card
number…etc.
DATABASE DESIGN
RULES
Rule 5: Avoid data redundancy
you should not include extra (redundant) fields in a table.
Redundant fields take up extra disk space and lead to data
entry errors because the same value must be entered in
multiple tables.
Rule 6: Do not include a field if it can be calculated from
other fields
A calculated field is made using the query generator as we
will see later.
161
** You should realize the importance of accuracy, case
sensitivity…etc in designing databases.
METADATA & HIERARCHY
OF DATA
Metadata: Data about data. Metadata describes how and when and
by whom a particular set of data was collected, and how the data
is formatted. A text document's metadata may contain information
about how long the document is, who the author is, when the
document was written, and a short summary of the document.
162
Hierarchy of Data: refers to the systematic organization of data,
often in a hierarchical form. Data organization involves fields,
records, files and so on.
DATA DICTIONARY
Data Dictionary: In database management systems, a file that
defines the basic organization of a database. A
data dictionary contains a list of all files in the database, the
number of records in each file, and the names and types of
each field. Most database management systems keep the
data dictionary hidden from users to prevent them from
accidentally destroying its contents.
163
Data dictionaries do not contain any actual data from the
database, only bookkeeping information for managing it.
Without a data dictionary, however, a database management
system cannot access data from the database.
CREATING TABLES
Create tab  Table design (in the tables group)
Fill in the table’s fields.
Choose a suitable data type for each field.
For example
text  Last Name
Date/time  Date Hired
Yes/No  US Citizen
164
Change the lengths of the text fields from 255 to 30
spaces.
CREATING TABLES
We need to make the Employee ID a primary key:
Select the Employee ID field then in the Table tools Design click Primary
Key tab
After you finish click the File tab  Save object as  then name your
table
165
Note that this is different from Save Database as which saves the whole
database.
CREATING COMPOUND
PRIMARY KEY
The two fields must be appear one after the other in the table
definition screen (plan ahead for that format).
Highlight one field, hold down the control key and highlight
the next field.
166
Go to table tools  design tab Primary Key
ADDING RECORDS TO
A TABLE
Double click the table’s name in the navigation pane at the
left of the screen then start typing data directly into the cells.
Enter your data one field value at a time.
Each time you finish entering a value, press Enter to move
the cursor to the next cell.
After you enter the data in the last cell in a row, the cursor
moves to the first cell in the next row and Access
automatically saves the record
167
No need to save through the File tab.
CREATING QUERIES
Using Calculated Fields in Queries:
E.g. suppose we have the following table.
168
if you have an existing field containing the number of boxes
of Girl Scout cookies sold, you may want to see how much
money was collected for each cookie sale. In this example,
the boxes sold for $3.95 each.
USING CALCULATED
FIELDS IN QUERIES
In this case we will create a calculated field in a query.
Create tab Query design
Don’t Forget the Colon.
169
Also the field name must be enclosed in square brackets.
USING CALCULATED
FIELDS IN QUERIES
How to format the calculated field output?
1. select the output column by clicking the line above the
calculated field expression.
2. the column darkens to indicate the selection.
170
3. Design tab  property sheet  format
AVOIDING ERRORS WHEN
MAKING CALCULATED FIELDS
1. Do not enter the expression in the criteria cell. Enter it in
the Field cell.
2. Spell, capitalize, and space a field’s name exactly as you
did in the table definition.
171
3. Don’t use parentheses or curly braces instead of the
square brackets.
“RELATING” TWO OR MORE
TABLES BY THE JOIN OPERATION
Suppose you want to see the last names, employee IDs, wage
rates, salary status, and citizenship only for US citizens and
hourly workers.
Problem: the data is spread across two tables.
Solution: add both tables and pull down the five fields you
need.
Step 1: Create tab  Query design
Step 2: Click one table name and hold down the ctrl button
while choosing the other table name.
172
Step 3: start pulling down the fields you need and add the
criteria expressions.
173
“RELATING” TWO OR MORE
TABLES BY THE JOIN OPERATION
“RELATING” TWO OR MORE
TABLES BY THE JOIN
OPERATION
you can use calculated fields using more than one table.
Just follow the same steps and add the calculated field in the
174
design view like what we did earlier.
TOTALS QUERIES
Assume that you want to see two pieces of information for
hourly workers:
1.
The average wage rate
2.
110 percent of the average rate
Step1:
Create the first query, click the design tab  Totals button in the
show/hide group. This will give us the average of the wage rate
field.
Note that: you should type the revised
heading for the wage rate field,
i.e. Average rate: wage rate.
N.B. we need the average of this field.
175
Also to get the hourly workers only,
enter Criteria=No.
TOTALS QUERIES
Now begin a new Query.
But instead of basing it on a table, we will base it on the
previous query.
176
Design the new query and create
a calculated field inside it.
USING THE DATE() FUNCTION IN
QUERIES
Access has two important date function features:
1. The built in Date() function which gives today’s date.
2. Date arithmetic lets you subtract one date from another
to obtain the difference-in number of days- between two
177
calendar dates.
USING THE DATE() FUNCTION IN
QUERIES
Suppose you want to give each employee a $1 bonus for
each day the employee has worked.
So, you need to calculate the number of days between the
employee’s date of hire and the date the query is run.
178
Date
arithmetic
USING TIME ARITHMETIC IN
QUERIES
Access allows you to subtract the values of time fields to get an
elapsed time.
179
In Access, subtracting one time from the other yields the
decimal portion of a 24-hour day.
E.g. if the employee worked 8 hours, the time arithmetic
function yields 0.333. That’s why we multiply by 24.
UPDATE QUERIES
Suppose you want to give all non-salaried workers a $0.5 pay
raise.
If you have 3 workers  change the wage rate data in the
table.
If you have 3000 workers  it would be much faster and
more accurate to change the wage rate by using an update
query that adds $0.5 to each non-salaried employee’s wage
180
rate.
UPDATE QUERIES
First start by making a select query.
181
Then click the update button
in the query type group.
UPDATE QUERIES
We will update only the nonsalaried workers by using a filter
under the salaried field.
182
We will write the updated
data in the Update to line
in the QBE grid.
UPDATE QUERIES
When you run the query, the following warning message will
appear.
183
Click yes, and the records will be updated.
DELETE QUERIES
Delete queries work like the update queries.
E.g. Suppose your company is purchased by the state of
Delaware. So you need to delete or “fire” all employees who
are not exclusively Delaware residents.
184
<>  not
SCENARIO
You have a table of medicines. One of them is now banned.
Create a query with the new requirements.
So what is the type of this query?
185
Delete Query
PARAMETER QUERIES
Suppose you want to know how many hours a particular
employee has worked.
1. Run a select query.
186
2. You will get a message
to enter the employee
ID.
Enter your employee ID
and you will get the
desired information
PRACTICE QUERIES
(P.33  37)
187
#2 Create a query that shows the last name, first name, date
hired, and state for employees who live in Delaware or were
hired after 12/31/99. The primary sort (ascending) is on last
name, and the secondary sort (ascending) is on first name.
The primary sort field must be to the left of the Secondary
sort field in the query setup.
N.B. you have 3 tables.
Employee  Last Name, First Name, Employee ID, Street
Address, City, State, Zip, Date Hired, Us Citizen.
Wage Data  Employee ID, Wage Rate, Salaried.
Hours Worked  Employee ID, Week #, Hours.
Use this table to solve the practice query.

MAKING FORMS
First select the table or query you want to base the form on
then select Create tab  form
When you create a form within another form  this is called a
subform
The Subform is useful when the form is based on one or
196
more tables.

Step 1: select the table  create  Form
197
Take the form into design view.
Design tab  make sure that the use control wizard option is
selected  click the subform/subreport button.
