FORGOT_PWD table. In addition, nearly three dozen functions were created along with
11 stored procedures and four packages. Of these objects there are a few of particular
interest, while the others were created to perform supportive functionality of the
application, such as performing tax calculations.
The APP_USER_SECURITY package is of interest because often times user’s
passwords are stored in the databases as clear text which could have security
implications. The APP_USER_SECURITY package contains a function that uses the
DBMS_OBFUSCATION_TOOLKIT.MD5 function to hash a password based on the
input of the user’s username and their password. The package body also contains a
function to check whether or not the user entered a valid password. This is done by
calling the GET_HASH function again and verifying that the hashed password stored in
the table is the same as the result of hashing the password entered.
There were a few stored procedures created to aid in the automatic assignment of
sales leads. The P_LEADASSIGN procedure was developed for automatically assigning
leads that were directly entered into the system through the application’s Web interface
or the XML upload interface. This procedure can take one parameter as input, the ID of
the lead (LID). Based on this LID, and through the use of other functions that were
developed, the procedure determines what sales staff is available to take over that lead for
the geographic area the lead is located in. The procedure identifies if the lead is Spanish
speaking and if it is then priority is given to bilingual sales staff. If there are multiple
salespeople available to take the lead then the procedure uses a round robin approach to
determine whom the lead should go to. The round robin approach is based on the time
the salesperson last received a lead. The salesperson that has the longest time span
