3. Data Types and Field Properties
Data types and field properties are used to format data so that
it can be used and managed.
The data type defines the value of a cell and the field
property defines the format of the data within the cell.
For example : the data type for a zip code field is number
and the field property is used to limit the size of the entry to 5
characters.
4. Why are data types important?
To control data.
In the example on the left,
the Age of data was
stored in descending
order, but because the
data type was not set as
Number, the field cannot
be sorted correctly.
In he example on the
right, the Adoption data
was correctly stored in
ascending order because
the data type for Date
was used.

5. Example of a Data Type
The data type
for the adoption
date field is
date/time
6. What data types are available?
Text
Memo
Number
Date/time
Currency
AutoNumber
Yes/No
Lookup Wizard
Note: OLE Object and Hyperlink data types are not
addressed in this objective.
7. When to use data Types:
Think of data types and
field properties as tool
that increase the power
of the database.
The default format for
all types is text.
Use a different data
types if you need to
control how the data in
a particular field will be
searched, sorted, or used
in calculations.
8. Why are field properties important?
To control how
data is entered in a
field
Requiring the same
format for all of the
phone numbers is a
way to ensure
accuracy
In this example, an Input Mask field property was used to force the user
to enter the telephone number in a specific format.
9. Field Properties:
• Field Size
• Format
• Input Mask
• Mask
Note: Only 4 field properties are mentioned and addressed in
this objective.
10. When to set field properties :
Use a field property if you want to
specify how the data is entered, what
data can be entered, and how the data
will appear.
11. Steps in Creating a Database
1.Plan the structure of the database (sketch on paper)
a) How will the data be grouped?
b) What will the field names be?
c) What will you name the database
1. Open and save a new database
2. Create a table
3. Enter the field namesal Set the data typesSet the field properties
4. Enter the data
