Data File needed for this Case Problem: Redwood.mdb (cont. from
Tutorial 1)
Redwood Zoo Michael Rosenfeld wants to find specific information
about the donors and their pledge amounts for the Redwood Zoo.
Youll help him find the information in the Redwood database by
completing the following:
1. Open the Redwood .2. Define the necessary one-to-many
relationships between the database tables, as follows: between the
primary Donor table and the related Pledge table, and between the
primary Fund table and the related Pledge table. (Hint: Add all
three tables to the Relationships window, and then define the two
relationships.) Resize the field lists, as necessary, to display
all the field names. Select the referential integrity option and
the cascade updates option for each relationship. 3. Use Design
view to create a select query that, for all pledges with a
TotalPledged field value of greater than 200, displays the DonorID
(from the Donor table), FirstName, LastName, PledgeID,
TotalPledged, and FundName fields. Sort the query in ascending
order by TotalPledged. Save the query as qryLargePledges, and then
run the query. 4. Use the qryLargePledges datasheet to update the
Pledge table by changing the TotalPledged field value for PledgeID
2976 to 750. Close the query. 5. Use Design view to create a select
query that, for all donors who pledged less than $150 OR who
donated to the Whale Watchers fund, displays the PledgeID,
PledgeDate, TotalPledged, FirstName, and LastName fields. a. Save
the query as qryPledgedOrWhaleWatchers, run the query, and then
switch to design view. b. Do a File | Save as and save the query as
qryPledgedAndWhaleWatchers. Change the query to select all donors
who pledged less than $150 and who donated to the Whale Watchers
fund. c. Save the revised query, and then run the query. Close the
query. 6. Use Design view to create a select query that displays
the DonorID (from the Donor table), TotalPledged, PaymentMethod,
PledgeDate, and FundName fields. a. Save the query as qry
PledgesAfterCosts. b. Create a calculated field named Overhead that
displays the results of multiplying the TotalPledged field values
by 15% (to account for overhead costs). c. Save the query, and then
create a second calculated field named NetPledge that displays the
results of subtracting the Overhead field values from the
TotalPledged field values. d. Format the calculated fields as Fixed
and set an appropriate caption for the NetPledge field. e. Sort the
results in ascending order by TotalPledged. f. Save the modified
query, and then run the query. Resize all datasheet columns to
their best fit, and then save and close the query.
7. Use the Pledge table to display the sum, average, and count
of the TotalPledged field for all pledges. Then do the
following:
a. Specify column names of Total Pledge, Average Pledge, and
Number of Pledges.
b. Change properties so that the values in the Total Pledge and
Average Pledge columns display two decimal places and the Fixed
format.
c. Save the query as qryPledgeStatistics, run the query, resize
all datasheet columns to their best fit. Save the query.
d. Change the query to display the sum, average, and count of
the TotalPledged field for all pledges by FundName. (Hint: Use the
Show Table button on the Query Design toolbar to add the Fund table
to the query.)e. Do a File | Save As menu option to save the query
as qryPledgeStatisticsByFund, f. Run the query, print the query
datasheet, and then close the query.
8. Close the Redwood database
