(iv) Another problem was that a user would search for branch location information of a bank. The user logs in by using User Name and Password. After the log in, on the “Search Location” page, the user enters and zip code of the location he wants to find, then clicks Find button. After that the system (application) gives a number of branch locations. The user now clicks “Request Information” for one of the branches. As soon as the user clicks “Request Information” button, the application breaks (displays “Page cannot be found” error). I logged this defect as a critical defect. When the developers and database administrator looked into it, then they found out that in one of the tables, the data was not recorded. In all the tables (UserProfile table, ClientID table and SessionID table), the data should be populated with the information entered by the user. For some reason, in one of the tables, it was blank (null). Once they wrote a small code to populate data (enter data) to the table, the application started working.
