Microsoft Access Lab

Create a Database for Emergency Room

11.5.2009

We have been working on data modeling, database management system and Microsoft

Access since last week. In this lab session, you will use Microsoft Access to create and

link tables, design queries to access data and enter data using forms.

The lab session is based on Microsoft 2! office suite. If you have earlier versions of

the Microsoft Access "rogram, the interface will be different. #therwise, you can use the

$%& 'irtual %om"uting (ab to access Microsoft Access 2!.

I am going to demonstrate how to use Access 2! to create the database in class.

The session will be recorded and I will make it available online as well.

atabase gra"h under the -ew +lank atabase. -ame the file $/0 and choose a "lace

on your hard drive to save it by clicking on the folder icon. Then click %reate button to

create the database.

2. The default entry "oint of Access is a -ew Table in datasheet view. %lick on the

esign button on the u""er left corner to toggle to design view. A dialog will "o" u"

asking for the name of the Table. -ame it 1ATI$-T. %lick #.

In the design view, "lease add additional fields to finish the table. The field names and

data ty"es for the 1ATI$-T table is listed in A""endi3 A.


4/18

4ou need to create two tables 5 1ATI$-T and $-%#&-T$/. 1lease see A""endi3 A

for the name and "ro"erty of each field. 1ay attention to the field si6e and data ty"e ofeach field.

Use Lookup Wizardto define the value of Arrival7Mode in the 1ATI$-T database. 4ou

need to define two columns with the first column as the code and the second column as

e3"lanations. The code and descri"tions are as follows8

01 Emergency Ambulance02 Patient Transport Service03 Public Transport

04 Private Transport05 Waling0! Police Transport0" Prison Transport#$ %t&er## 'ot (no)n*

4ou can kee" the original "rimary key +,automatically added by Microsoft Access, or

you can remove the default "rimary key and make two new ones like I did in A""endi3

A. If you kee" the old "rimary keys, make sure you name them M/7-# 9in both tables:

and $-%#&-T$/7I. ee" the data ty"e as Auto-umber is #.

After creating the two tables, your Table work "ane should look like this.

Two new tables

;. %lick on the atabase Tools tab on the /ibbon. %lick /elationshi"s to bring u" the

dialog for choosing table to build relationshi"s. Add both 1ATI$-T and $-%#&-T$/

tables to the relationshi" window. Then close the dialog. %licking the M/7-# field

within the 1ATI$-T table, without release, dro" it over the M/7-# within the$-%#&-T$/ table. A new $dit /elationshi"s Window will a""ear. Make sure you

check $nforce /eferential Integrity0.

After clicking %reate button, you can see the two tables are linked with each other.

the center of the =orm Wi6ard windows to move all fields from the left side of the

window to the right side of the window. 4ou can also use to move the fields one by

one.

%lick Next. -ame the form $ncounter. %hoose Modify the Forms Design, then "ress

Finish.


10/18

4ou should see the form design interface like the image below. 4ou can click on a data

entry field to highlight. =eel free to resi6e or move any entry field to accommodate

"otential data after you create the datable.

.

1ress the button on the left u""er corner to toggle the mode to view form. 4oucan see all your fields are listed in a column layout. 1lease note the form automatically

designed the Arrival7Mode as a dro" down list since we used (ooku" wi6ard in our

table design. There is no need to enter any data here yet.


11/18

=ollow the same ste" to create another form for the 1ATI$-T table.

@. -ow you have the two forms to enter data into the data tables 1ATI$-T and

$-%#&-T$/. 1o"ulate some fictional data into the database through the two forms.

4ou need to "o"ulate the 1ATI$-T table first, then the $-%#&-T$/ table. 1lease

note that the M/7-#s in the $-%#&-T$/ table must e3ist in the 1ATI$-T table first.

At the bottom of the form 9in view mode:, you can see a row of buttons like

. It is the record navigation bar allows you to go to

the beginning of the records, backward one record, forward one record, , go to the last

record, and enter news record.

$nter three "atients and @ encounters for query "ractice in ne3t ste". 1lease have one

encounter with the Arrival7Mode as Walking since we are going to use it in our ne3t

ste".

. ?uery data from the database.

-ow you have data in the Access database. 4ou can use query to retrieve the data as

you needed. =or e3am"le, you might be interested in listing all "atients who walked into

the $/. Microsoft Access uses the method ?uery by $3am"le 9?+$: to visually dis"lay

the query.

=irst, you need to click the ?uery esign button on the %reate tab to access the

?ueries work s"ace.

%lick Create query in Design ie!. 4ou should be able to see the query design view

and the "ho! #a$%ewindow.


13/18

Add two tables to the ?uery esign view by highlighting the table and "ress &dd

button. %lose the "ho! #a$%ewindow once you have both tables added.

In the first field, choose 1ATI$-T.(-ame. In the second field, choolse

1ATI$-T.=-ame. In the third filed, choose $-%#&-T$/.Arrival7Mode. =or the =ield

$-%#&-T$/.Arrival7Mode, enter ' ()*+into the %riteria cell.


14/18

*ave the ?uery as 1atient7Walkin. 1ress the run button on the ?uery esign toolbar

to run the query. The result of my query is as follows. 1ress the *?( view from the

dro"down list

1ress the *?( view from the dro"down list to view the *?( code behind the scene.


15/18

#ther than listing the "atients meet the criteria, Microsoft Access can also "erform

sim"le calculation. =or e3am"le, you want to count the number of "atients walked in the

$/. 4ou can use the ,ounte3"ression in Microsoft Access query to calculate the data.

Add the one more field 1ATI$-T.M/7-# to the query design view. 1ress the

button on the query design toolbar to dis"lay the row #ota%.

The total

row

a""ears

1ress *?( 'iew

to view the *?(

code.


16/18

%hange the #ota%cell for the field M/7-# to %ount from the dro" down list.

-ow run the query again. 4ou can see my "atients walk in the $/ twice.

.

The query we Bust did is called select query. There are other ty"es of queries available

in Microsoft Access. %lick on the button on the query design toolbar to view the

choice of other query. It is not required in this session to design other ty"e of queries,

but feel free to try those.

The total cell is

changed from

grou" by to

count.
