The document outlines the design and implementation of a Medical Store Management System, focusing on customer billing and membership management. It includes various technical components such as data flow diagrams, entity relationship diagrams, and SQL scripts to handle customer transactions and discounts. The system enables operators to manage customer data efficiently while noting limitations like the inability to check multiple medicines at once.

3. NARRATIVE OF PROJECT
This project is to design medical store management
system. The main focuses is on the billing area. This
system identifies whether the customer is eligible for the
discounts or not. This is done by checking the existing
database for whether the customer is registered. If the
customer is a member then he can enjoy the discounts and
offers. In case if the customer is not a member and is
willing to be a member then he is issued a membership
after storing his information in the database.

11. NORMALIZATION(1ST
NORMAL FORM)
OWNER = #OWNER_ID + FIRST_NAME + LAST_NAME + CONTACT_NO
MEDICAL STORE = #MEDICINE_CODE + QUANTITY + MEDICINE_TYPE +
MEDICINE_NAME + MFG_DATE + EXP_DATE +MFG_BY + PRICE
MMEMBER = #MEMBER_ID + LAST_NAME + START_DATE + END_DATE +
CONTACT_NO
MEMPLOYEE = #E_ID + E_NAME + STREET_NO + APT_NO + CITY +
CONTACT_NO + JOB + SALARY
BILLING _INFO = #CUSTOMER_ID + CUSTOMER_NAME + STREET_NO +
APT_NO + CITY + CONTACT_NO

12. NORMALIZATION(2ND
NORMAL FORM)
OWNER = #OWNER_ID + FIRST_NAME + LAST_NAME + CONTACT_NO
MEDICAL STORE = #MEDICINE_CODE + QUANTITY + MEDICINE_TYPE +
MEDICINE_NAME + MFG_DATE + EXP_DATE +MFG_BY + PRICE
OWNED BY = #OWNER_ID + #MEDICINE_CODE
MMEMBER = #MEMBER_ID + LAST_NAME + START_DATE + END_DATE +
CONTACT_NO
REGISTER = #M_CODE + #ID
MEMPLOYEE = #E_ID + E_NAME + STREET_NO + APT_NO + CITY +
CONTACT_NO + JOB + SALARY
WORK FOR = #E_ID + #MEDICINE_CODE
BILLING _INFO = #CUSTOMER_ID + CUSTOMER_NAME + STREET_NO + APT_NO +

GENERATES = #CUSTOMER_ID + #MEDICINE_CODE

13. SQL SCRIPT & OUTPUT REPORT(1)
 Customer is searching for a medicine called droxyl 500 that is available and
the cost is $11

14. SQL SCRIPT & OUTPUT REPORT(2)
 Is the customer a valid member?
 This is checked by member id or the phone number

15. SQL SCRIPT & OUTPUT REPORT(3)
 As the customer is a valid member he receives a discount of 5%.

16. SQL SCRIPT & OUTPUT REPORT(4)
 Suppose the customers membership id is expired and he renews the
membership

17. SQL SCRIPT & OUTPUT REPORT(5)
 Suppose customer is searching for a medicine called cefakind 250 which is
not available

18. SQL SCRIPT & OUTPUT REPORT(6)
 Customers Final bill receipt

19. ADVANTAGES
 This system provides an easy way for the casher
to determine whether the customer is a valid
member so that he can provide them with
discount.
 This system is also provides great help to the
casher to add or update new or existing members
respectively

20. DISADVANTAGE
 As every coin has a two side this system also
suffers from disadvantage.
 Multiple medicines can not be checked for a
customer.

21. CONCLUSION
 This system provides an easy way for the operator
to interact with the database and to manipulate
the data in the database.
 The operator can add, delete and update the
records in the database with ease.
