Business Programming II Assignment 4

Date Due:  

Learning Objective:   In assignment 4, the student will learn how to use Indexed Keyed sequence files to add, update, and delete business transactions. 

Definition of Problem:   “S3C World Wide” would like to create an indexed database file for the Customer-info and Customer-order databases created in Assignment 3.     

 Your next assignment is the following: 

1)      Write a brief program to allocate an indexed file for the Customer-info and Customer-order databases. 25% 

2)      Modify your program from Assignment 3 to update or add to each indexed file, in place of the sequential.  Remember if the customer already exists; update the customer’s information.  If no customer exists, add a new customer record.  Each order is assigned a unique number and therefore should always be added. 75% 

Total Credits = 100%
