tables and datatypes2

1. Microsoft Access
Chapter 2: Creating Microsoft Access
Tables
Tables are the foundation of an Access
database. Access stores data in tables.
This lesson
teaches you how to create a table, add
fields to a table, assign data types to
fields, and set field properties.

2. A table is a set of columns and rows. Each column is called a field.
Within a table, each field must be given a name and no two fields
can have the same name. Each value in a field
represents a single category of data. For example, a table might have
three fields: Last Name, First Name, and Phone Number. The table
consists of three columns: one for last name, one for first name, and
one for phone number. In every row of the t able, the Last Name field
contains

3. the last name, the First Name field contains the first name, and the
Phone Number field contains the phone number. Each row in a table
is called a record.

4. All of the data in a table should refer to the same subject. For
example, all of the data in the Employees table should refer to
employees, all of the data in the Students table should refer to
students, and all of the data in the Courses table should refer to
courses.
Steps To add fields to a table:
Go around field area
Go to the datasheet
Rename
Click the field

5. 1. Click the Add New Field column label.
2. Activate the Datasheet tab.
3. Click Rename in the Fields & Colum ns group.
4. Type the field name.
5. Press Enter. Access creates the field.
6. Type the next field name. Access creates the field. Cont inue
until you have created all of the fields in your table.
7. Press Enter without entering a field name to end your entries.
Steps To add fields to a table:

6. After you create a table, you must name and save it.
Otherwise your file is going to lost once lost its not easy to find it
Steps To save a table:
 Click the Save button on the Quick Access toolbar. The Save As
dialog box appears.
 Type the name you want to give your table.
Click OK. Access names your table.

8. Tip: You can use the Rename option at any time to
rename any column. For example, you can rename
the ID column Employee ID.

9. Understanding Data Types
In Access, you use data types to specify the type of data each field
can capture. When creating tables in Access, you need to select a
data type for each column of data. The Short Text data type is a
popular choice since it lets you enter almost any character (letter,
symbol, or number). However, careful selection of data types can
help you take advantage of more Access features (such as data
validation and functions), and improves the accuracy of the
information you’re storing.

10.  The several type of data type
Text
Memo
Number
Time/Date
Yes or No
Auto Number
Microsoft Access Data types

11. Alphanumeric data. Use for text and for numbers that are not used
in mathematical
calculations. Use for names, addresses, and other relatively short
pieces of text. Can store up to 255 characters.
Text

12. Long text. Use for long pieces of text, such as notes and long
descriptions. Can store up to 64,000 characters.
Memo
Number
Numeric data. Use for numbers you want to use in mathematical
calculations.

13. Use for dates and times.
Date/ Time
AutoNumber
Unique sequential numbers or random numbers automatically
inserted when you create a
record. Use to create a primary key.

14. Logical data. Use when only one of two values is valid. Yes/ No, True/
False, etc.
Yes/ No

15. Short example y created A field named Age so which data type is
good for placing age ? The answer is Number so
Steps To assign a data type or format to a field:
1. Go the field you want to assign data type
2. Active of go to the datasheet
3. Then assign the type of data type you want
To assign a data type or format to a field:

16. Steps To assign a data type or format to a field:
1. Go the field you want to assign data type
2. Active or go to the datasheet
3. Then assign the type of data type you want

17. Class Work
1. Create A database name Vision as shown the image

18. 2. Then click Create the Vision database is being created and check at
the top of the title bar in Microsoft Access.

19. 3. After creating the database create a table, select the Create tab in
the toolbar at the top of the screen. Then click on the Table Design
button in the Tables group. Next, add the fields to the table. In this
example, we've added the fields Customer_ID, First_Name,
Last_Name

20. 4. Then right click on the Table and choose table Design button as
see to the picture below then save its name as Semester2

21. 5. Next, add the fields to the table. In this example, we've added the
fields Customer_ID, First_Name, Last_Name

22. 6. Good job now save the fields you entered and close the design
table by right clicking the table title then again open the table
semester2 it will appear like this image below

23. 7. Then fill the fields like the information of this image below
