Refer to section Computer to Computer connectivity via PPI in your course handouts…You have studied in this course that using parallel port, we can transmit One Byte at once and thus it is faster than serial communication. You can also find the details of the procedure that describes how to achieve communication via parallel port between two computers. It is amazing to see that in this protocol, Byte is not transmitted as a whole; rather it is transmitted in the form of Nibbles. You are required to answer the following question.

Is it possible to transmit One Byte data at once via PPI between two computers? If yes then How and if not then why?

CS504: Software Engineering-I Assignment no 3 Spring 2012 Idea Solution

In assignment 2, you were asked to develop use-case model and data flow diagram for HealthCare Sale Management System. Continuing further, you are now required to draw sequence diagrams for the some of the use cases identified in previous assignment.

Remember that this assignment is based on solution of your previous assignment (Assignment 2).

Description: Advance HealthCare is a medicine manufacturer company which manufactures medicines and sells to its customers. Advance HealthCare wants to develop an online system which will facilitate to manage the routine tasks of medicine sales and will convert the manual working in a computerized system. The system is meant to manage almost every aspect of the medicine sale system such as maintaining the stock record of the medicine, suppliers/companies accounts, purchase record, customer (patient) record, sales invoice generation, employees’ record etc. This system will maintain all the sales of medicines to customer and purchase from supplier. The medicine stock will be managed along with their batch numbers, expiry date, rate and quantity. When the medicine is purchased, and record is entered, the stock record will be updated immediately. The system will also handle the accounts including payments to suppliers and receiving from customers. The proper ledgers of every account will be maintained. The system will also help in maintaining the employees’ record that includes storing their name and other particulars along with their salary package. The system will generate many sophisticated reports including stock reports, ledger prints and rate lists. The system will not generate any advanced accounting reports as trial balance, balance sheet, Operating Expense Report and worksheets. The System should be user friendly, technology independent and platform independent. The System service should have availability most of the time in the day. It must be capable of supporting multiple users at a time without affecting the performance. It should be able to complete its on-going operations in spite of any error or problem within defined response time.

Question:

 You are required to draw Sequence Diagrams for the following two Use Cases:

1)  Add Account

  HINT: Using this use case, the manager will be able to add new account into the system.

2)  Update Item

  HINT: This use case will allow the user to update the information for an item (medicine) in the inventory.
