Remove a Borrower

Interface Definitions

• Calls Search for Borrower

Inputs from the user:

• ID number of the person being sought
• Name of the person being sought
• Any Borrower information fields can be filled in. A list of all the possible matches appears on the bottom of the screen - the search is complete when only one match remains, or the Librarian selects a borrower from the match list.
• A confirmation if the Borrower is to be deleted.

Outputs to the user:

If Successful:

• A message confirming the deletion, and returns to caller.

Data Abstractions

• Accesses the Borrower data store.
• Accesses the Fines data store.

Design

• The Search for Borrower window appears, and once the Librarian has isolated a specific borrower, they have the opportunity to delete.
• If the borrower has outstanding fines, they may not be deleted. Fines would have to be cleared in the Fines module first.

Sub-Modules

• None.

Error Handling

Search Unsuccessful:

• The list of matches would remain empty.

Syntax Errors in ID or name:

• User is informed of a syntax error.
• The proper format for data entry is explained. The user can then edit their old input and search again, or abort.

Imports

• Reads the Fines data store.

Exports
