Design

Environment: GUI (graphical user interface)

Interface: Pop-up window.

• Every item from Data Abstraction will be entered in it's own text-box.
• These text-boxes will allow strings larger than the text-box size to be entered.
• The add borrower will be a batch process. i.e. none of the new information entered will be updated until the update-Borrower button/key is activated.
• When the button/key is entered certain items will be checked for syntactical errors (for errors see ERROR HANDLING).
• PROVINCE will be checked against existing provinces.
• CITY will be checked against existing cities.
• POSTAL_CODE will be checked for format against existing formats.
  • e.g. a#a-#a# ,where #= number, a= letter
• PHONE number will be checked for format against existing formats.
  • e.g. ###-####-#### ,where #= number.
• IDENTIFICATION will be checked against will be checked against all other ID's in the system, with the exception of one previously assigned the borrower.
