									                               Creating an Access Database


To start an Access Database, you should first go into Access and then select file, new.




Then on the right side of the screen, select Blank database.




Give your database a name where it says db1 and save the file as a mdb file




You will then be brought to the following screen:

                               Creating an Access Database


In Access, you first need to create a table with your data. The table is similar to an Excel
Spreadsheet. It has rows and columns. In this menu below, Tables is selected and then
you can Create a table in one of three ways. Design view, by the wizard, or by entering
data.




Once you create a table, you can then create queries to extract data and create a user
friendly Form to enter data into your table with a visual flare.

In this lesson, we will be creating a table in Design View. You can enter the field names,
data type and a description of the field.

                              Creating an Access Database




Begin Entering the field names of your database in the description. In this Example we
are creating a database for Software Licenses on computers. It is important to know all
of your fields ahead of time. Think of the fields as column headings on an Excel
Spreadsheet.




The data type for each field can be straight forward text, yes or no, a memo or even a
drop down for you to select from a list. When you build a table, think about how you
would like the user to interface with the data.


For instance, in the above example, we do not want the user to have to type in the
Software type each time. So when you go to data type, you can select from the dropdown
Lookup Wizard

                              Creating an Access Database



This will then generate a series of menus for you to answer questions to.
Select “I will type in the values that I want”.




When you are finished with the table, go to save and name your table




Select OK. You will then be asked to create a primary key.




3/2/2006                                                                    4
                                               Creating an Access Database



                 A primary key is not necessary however when possible, you should create one. Primary
                 keys uniquely identify each record in the table. They can be created in one of 3 ways.
                 Auto number, Single primary key (as in a social security number) Multiple-field (two or
                 more fields make up the record.

                 Note that when you create a primary key, Access will not allow you to enter the same
                 value in the primary key field more than once. We will manually assign a primary key by
                 selecting the key on the tool bar.




  You must
  select the
  primary
  key item in
  the table
  before you
  hit the key.




Once you
select a key
you must
determine if
duplicate
entries are
allowed.




                 3/2/2006                                                                         5
                                                  Creating an Access Database




In this example,
we want to allow
duplicates
because a person
may be entered
for more than
one license.




                   Save the table and then “x” out.


                   You have now created the frame work for entering the data. You can enter the data
                   directly into the table like you would for an Excel Spreadsheet, or you can create a User
                   friendly form.


                   Lets first do one entry with the table and then we will create a form.

                   Go to File Open and you can then select Table under the object menu.
                   Double Click on Software License Table to open it.




                   A spreadsheet will populate for you to begin entering data the same way you would with
                   Excel:




                   3/2/2006                                                                           6
                                                  Creating an Access Database




                    Now we are going to switch to creating a form to appeal more to the user for data entry.

                                      Creating an Entry Form using the Wizard




                    Select form on the left side of the database window and double click on Create form by
                    using wizard. You will be creating the form based on the Software License Table




Select the fields
you want on the
form. If you
want all, select
the double
arrows-
everything will
move to the
right.




                    Click on next and then select the layout of your form.
                    3/2/2006                                                                          7
                              Creating an Access Database




You can select any one of the layouts to see how it will display. Make a selection and
click next. You can then select a style for the form.




Select Next and Apply a name for your form

   When you are in design view, you will see the grid of the form.




   Enlarge the form and modify it by adjusting the size of the boxes.


   While in the design view, you can move the various items around and you can also add
   buttons to Add, Delete, or Print records. When you go to add buttons, make sure you are
   in Design view.




Select Tool

view




   The tool box will appear on the tool bar. There you can select an icon and then move the
   cursor to the form. Double click and then you can add a button. See the example below.
   Select the button tool on the tool bar and then double click on the form where you would
   like to see the button.




                                                                Select the
                                                                button

                                                     Button shows. Now decide
                                                     what you want the button to
                                                     do. Select a category and
                                                     action.


In this example we will have the button be a find next button. So now that it is selected
hit Next on the wizard. Sometimes you can select different pictures for the button.




Click next. Give the button a name on the next screen.

                               Creating an Access Database




Filter by form allows you to perform searches of a table, form or query in a database. It
allows you to quickly find and display records that meet specific criteria.

Lets try it! With our software license table open, select the Filter by form icon




The filter by form window then appears as it relates to the table.




To clear any previous filter, click on the Delete icon.     Notice the >200 will
disappear.




Now we can do a new filter. Click on the cell beneath field name that you want to use to
filter the records. In this example we will select Software type. A drop down appears




Select one of the drop downs and then select the apply filter icon.

Click again to remove the filter. Remember you can filter with more than one field.

                    Creating A Query Using the Wizard

When you create a query to find information, you ask Access to find information that
meets specific criteria. It is like a filter, however it is saved, so you can run it over and
over.

To begin, Select Queries under the object menu and also Create query using Wizard.




Make sure you have the correct table selected for your query. Select the available fields
and move them to the column on the right.
