I’m just plain stuck. I hate databases!!!! Please help!!!! Thank you!!

 

Professional Litigation User Services (PLUS) is a company that creates all types of visual aids for judicial proceedings. Clients are usually private law firms, although the district attorney’s office has occasionally contracted its services. PLUS creates graphs, maps, timetables, and charts, both for computerized presentations and in large sizes for presentations to juries. PLUS also creates videos, animations, presentation packages, slide shows, and anything else of a visual nature that can be used in a judicial proceeding to make, clarify, or support a point.

Raj Jawahir is responsible for tracking the daily payments received from PLUS clients. You will help him maintain the Payments database by completing the following:

Figure 1

Field Name Data Type Description Field Size Other Properties
Payment# text primary 5  
Firm# text foreign 4  
DatePaid date/time     format: mmm dd yyyy (custom format)
AmtPaid currency     format: standard

Figure 2

Payment# Firm# DatePaid AmtPaid
10031 1111 06/03/2001 2500.00
10002 1147 06/01/2001 1700.00
10015 1151 06/02/2001 2000.00
  1. Start Microsoft Access and open the Payments database located in the ‘Payments’ zip file.
  2. Create a table named Payment using the table design shown in Figure 1 above (Hint: Make sure that you include spaces between components of the custom format for the Date Paid field “mmm dd yyyy”).
  3. Add the payment records shown in Figure 2 to the Payment table.
  4. Modify the structure of the Payment table by completing the following:
    1. Field Name: Deposit#
    2. Data Type: Text
    3. Field Size: 3
  5. Move the DatePaid field so that it follows the AmtPaid field.
    • Use the Payment data sheet to update the database as follows. Enter the following Deposit# values for the 3 records:
      1. 101 for Payment# 10002
      2. 102 for Payment# 10015
      3. 103 for Payment# 10031
    • Add a record to the Payment data sheet with the following field values:
      1. Payment#: 10105
      2. Deposit#: 117
      3. Firm#: 1103
      4. AmtPaid: 1750.00
      5. DatePaid: 06/20/2001
  6. Raj created a database named PlusPays that contains recent payments in the Payment Records table. The Payment table you created has the same format as the Payment Records table. Copy all the records from the Payment Records table in the PlusPays database (located in the Payments.zip folder) to the end of your Payment table.
  7. Use the Access Help system to learn how to resize data sheet columns to fit the data, and then resize all columns in the data sheet for the Payment table.
  8. For Payment# 10002, change the AmtPaid value to 1300.00.
  9. Delete the record for Payment# 10096.
  10. Take a screenshot of the first page of data from the Payment table data sheet, and then save and close the table.
  11. Save the .accdb file when you are finished.

  • Complete all of the steps outlined above in the assignment description.
  • When you are finished, take a screenshot of the first page of data from the finished data sheet. Save a copy of the database file, and name it U2A1LastName.accdb.

    • What potential problem do you see with the Deposit# field?
    • What business assumptions were made when defining this table?
