Microsoft Access Description
- Microsoft Access is a powerful
program to create and manage your databases. It has many built in
features to assist you in constructing and viewing your information.
Access is much more involved and is a more genuine database
application than other programs such as Microsoft Works.
This tutorial will help you get started with Microsoft Access and may
solve some of your problems, but it is a very good idea to use the
Help Files that come with Microsoft Access, or go to Microsoft's web
site located at
http://microsoft.com/office/access/default.htm
for further assistance.
First of all you need to understand how Microsoft Access breaks down a
database. Some keywords involved in this process are: Database
File, Table, Record, Field, Data-type. Here is the Hierarchy that
Microsoft Access uses in breaking down a database.
|
Database File:
This is your main file that encompasses the entire database and
that is saved to your hard-drive or floppy disk.
Example) StudentDatabase.mdb |
Table:A
table is a collection of data about a specific topic. There can be
multiple tables in a database.
Example #1) Students
Example #2) Teachers |
Field:Fields
are the different categories within a Table. Tables usually
contain multiple fields.
Example #1) Student LastName
Example #2) Student FirstName |
Datatypes:Datatypes
are the properties of each field. A field only has 1 datatype.
FieldName) Student LastName
Datatype) Text |
This tutorial will help you get started with Microsoft Access and may
solve some of your problems, but it is a very good idea to use the
Help Files that come with Microsoft Access (or any program you use for
that matter), or go to Microsoft's web site located at
http://microsoft.com/office/access/default.htm
for further assistance.

Starting Microsoft Access
- Two Ways
- Double click on the Microsoft
Access icon on the desktop.
- Click on Start --> Programs -->
Microsoft Access
Back to top
Creating New, and Opening Existing Databases
The above picture gives you the option
to:
- Create a New Database from scratch
- Use the wizard to create a New Database
- Open an existing database
- The white box gives you the most recent databases you have used.
If you do not see the one you had created, choose the More Files
option and hit OK. Otherwise choose the database you had previously
used and click OK.
Back to top
Create a database using the
Database Wizard
- When Microsoft Access first starts up, a dialog box
is automatically displayed with options to create a new database or
open an existing one. If this dialog box is displayed, click Access
Database Wizards, pages, and projects and then click OK.
If you have already opened a database or closed the dialog box that
displays when Microsoft Access starts up, click New Database on
the toolbar.
- On the Databases tab, double-click the icon
for the kind of database you want to create.
- Specify a name and location for the database.
- Click Create to start defining your new
database
Back to top
Create a database without using the Database Wizard
- When Microsoft Access first starts
up, a dialog box is automatically displayed with options to create a
new database or open an existing one. If this dialog box is displayed,
click Blank Access Database, and then click OK.
If you have already opened a database or closed the dialog box that
displays when Microsoft Access starts up, click New Database on
the toolbar, and then double-click the Blank Database icon on
the General tab.
Specify a name and location for the database and click Create.
(Below is the screen that shows up following this step)

Tables
A table is a collection of data about a specific topic, such as
students or contacts. Using a separate table for each topic means that
you store that data only once, which makes your database more efficient,
and reduces data-entry errors.
Tables organize data into columns (called fields) and rows
(called records).
Back to top
Create a Table from scratch in Design view
- If you haven't already done so,
switch to the Database Window You can press F11 to switch to the
Database window from any other window.
Double-Click on "Create table in Design view".
(DESIGN VIEW)
Define each of the fields in your table.
- Under the Field Name column, enter the categories of your table.
- Under Data Type column, enter the type you want for you
categories.
- The attribute of a variable or field that determines what kind
of data it can hold. For example, in a Microsoft Access database,
the Text and Memo field data types allow the field to store either
text or numbers, but the Number data type will allow the field to
store numbers only. Number data type fields store numerical data
that will be used in mathematical calculations. Use the Currency
data type to display or calculate currency values. Other data
types are Date/Time, Yes/No, Auto Number, and OLE object
(Picture).
- Under the Description column, enter the text that describes what
you field is. (This field is optional).
- For our tutorial enter the following items:
Back to top
Primary Key
- One or more fields (columns) whose value or values uniquely
identify each record in a table. A primary key does not allow Null
values and must always have a unique value. A primary key is used to
relate a table to foreign keys in other tables.
- NOTE: You do not have to define a primary key, but it's
usually a good idea. If you don't define a primary key, Microsoft
Access asks you if you would like to create one when you save the
table.
- For our tutorial, make the Soc Sec # field the primary key,
meaning that every student has a social security number and no
2 are the same.
- To do this, simply select the Soc Sec # field and select the
primary key button
- After you do this, Save the table
Back to top
Switching Views
- To switch views form the datasheet (spreadsheet view) and the
design view, simply click the button in the top-left hand corner of
the Access program.
|
Datasheet View |
Design View |
Displays the view, which allows you to enter raw data into your
database table. |
Displays the view, which allows you to enter fields, data-types,
and descriptions into your database table. |
Back to top
Entering Data
- Click on the Datasheet View and simply start "chugging" away by
entering the data into each field. NOTE: Before starting
a new record, the Soc Sec # field must have something in it,
because it is the Primary Key. If you did not set a Primary Key then
it is OK.
Back to top
Manipulating Data
- Adding a new row
- Simply drop down to a new line and enter the information
- Updating a record
- Simply select the record and field you want to update, and
change its data with what you want
- Deleting a record
- Simply select the entire row and hit the Delete Key on the
keyboard
Back to top
Advanced Table Features w/Microsoft Access
- Assigning a field a specific set of characters
- Example) Making a Social Security Number only allows 9
characters.
- Switch to Design View
- Select the field you want to alter
- At the bottom select the General Tab
- Select Field Size
- Enter the number of characters you want this field to have
- Formatting a field to look a specific way (HINT: You do not
need to assign a field a specific set of characters if you do this)
- Example) Formatting Phone Number w/ Area Code (xxx) xxx-xxxx
- Switch to Design View
- Select the field you want to format
- At the bottom select the General Tab
- Select Input Mask Box and click on the ...
button at the right.
- Select Phone Number option
Click on Next
Leave !(999) 000-0000 the way it is. This is a default.
Click Next
Select which option you want it to look like
Click Next
Click Finish
Selecting a value from a dropdown box with a set of values
that you assign to it. This saves you from typing it in each time
- Example)Choosing a city that is either Auburn, Bay City, Flint,
Midland, or Saginaw
- Switch to Design View
- Select the field you want to alter (City)
- At the bottom select the Lookup Tab
- In the Display Control box, select Combo Box
- Under Row Source Type, select Value List
- Under Row Source, enter the values how you want them
displayed, separated by a column. (Auburn, Bay City, Flint,
Midland, Saginaw)
- NOTE:This will not alphabetize them for you, so you
will have to do that yourself. It should look something like
this:
- Select in the datasheet view and you should see the change
when you go to the city field.

Relationships
After you've set up multiple tables in your Microsoft Access
database, you need a way of telling Access how to bring that information
back together again. The first step in this process is to define
relationships between your tables. After you've done that, you can
create queries, forms, and reports to display information from several
tables at once.
A relationship works by matching data in key fields - usually a field
with the same name in both tables. In most cases, these matching fields
are the primary key from one table, which provides a unique identifier
for each record, and a foreign key in the other table. For example,
teachers can be associated with the students they're responsible for by
creating a relationship between the teacher's table and the student's
table using the TeacherID fields.
Having met the criteria above, follow these steps for creating
relationships between tables.
- In the database window view, at the top, click on Tools --->
Relationships
- Select the Tables you want to link together, by clicking on them
and selecting the Add Button
- Drag the primary key of the Parent table (Teacher in this case),
and drop it into the same field in the Child table (Student in this
case.)
- Select Enforce Referential Integrity
- When the Cascade Update Related Fields check box is set,
changing a primary key value in the primary table automatically
updates the matching value in all related records.
- When the Cascade Delete Related Records check box is set,
deleting a record in the primary table deletes any related records
in the related table
- Click Create and Save the Relationship
Back to top
Forms
A form is nothing more than a graphical representation of a table.
You can add, update, delete records in your table by using a form.
NOTE: Although a form can be named different from a table, they both
still manipulate the same information and the same exact data. Hence, if
you change a record in a form, it will be changed in the table also.
A form is very good to use when you have numerous fields in a table.
This way you can see all the fields in one screen, whereas if you were
in the table view (datasheet) you would have to keep scrolling to get
the field you desire.
Back to top
Create a Form using the Wizard
It is a very good idea to create a form using the wizard, unless you
are an advanced user and know what you are doing. Microsoft Access does
a very good job of creating a form using the wizard. The following steps
are needed to create a basic form:
- Switch to the Database Window. You can do this by pressing F11 on
the keyboard.
- Click on the Forms button under Objects on the left
side of screen
- Double click on Create Form Using Wizard
- On the next screen select the fields you want to view on your
form. Most of the time you would select all of them.
- Click Next
- Select the layout you wish
- Click Next
- Select the style you desire...HINT: if you plan on printing
your form, I suggest you use a light background to save on printer
toner and ink
- Click Next
- Give you form a name, and select Open the Form and enter
information
- Select Finish
- You should see your form. To adjust the design of your form,
simply hit the design button (same as with the tables), and adjust
your form accordingly
Back to top
Reports
A report is an effective way to present your data in a printed
format. Because you have control over the size and appearance of
everything on a report, you can display the information the way you want
to see it.
Back to top
Create a Report using the Wizard
As with the Form, it is a very good idea to create a report using the
wizard, unless you are an advanced user. Microsoft Access does a very
good job using the wizard to create reports.
- Switch to the Database Window. You can do this by pressing F11 on
the keyboard.
- Click on the Reports button under Objects on the
left side of screen
- Double click on Create Report Using Wizard
- On the next screen select the fields you want to view on your
form. Most of the time you would select all of them.
- Click Next
- Select if you would like to group your files. Keep repeating this
step for as many groupings as you would like.
- Click Next
- Select the layout and the paper orientation you desire
- Click Next
- Select the style you desire...HINT: if you plan on printing
your report, I suggest you use a light background to save on printer
toner and ink
- Click Next
- Give you report a name, and select Preview the Report
- Select Finish
- You should see your report. To adjust the design of your report,
simply hit the design button (same as with the tables), and adjust
your report accordingly
Back to top
Creating Mail Merge Labels using a Wizard
Microsoft Access lets you create Mailing Labels for your database
that you have. To do this do the following:
- Switch to the Database Window. You can do this by pressing F11 on
the keyboard.
- Click on the Reports button under Objects on the
left side of screen
- Click on New
- Select Label Wizard and the table you would like to get
your information from.
- Click OK
- Select the layout of your labels
- Click Next
- Select the font size and color you want on each label
- Click Next
- Select how you want your label to look
- Click Next
- Select how you want your labels sorted
- Give your label report a name and preview it
