<b>I.STATEMENTS OF USER AND SYSTEMREQUIREMENTS.</b>

Currently, I am working as a programmer at a technology company. This project is a company project. The customer asked the company to make a store management software for sale. Include activities that make it easier for the store to manage drug sales. egstaff management, drugs and prices, inventory, order management…

The pharmacy management system has 3 main roles: Staff management, drug management and orders management

<b>As pharmacist management:</b>

➢ I want to add and edit the Staff information or delete the Staff information when they no longer work at the store

<b>As drug management:</b>

➢ I see what drugs are in the store and the different names of them.

➢ I want to add and delete drug information such as drug name or price of each drug.

<b>II.Design The Relational Database System</b>

According to a recent survey of pharmacies, It is difficult for pharmacies to manage their drugs as well as their orders and Staff, especially inmedium to large drugstore chains for the following reasons:

➢ The amount of medicine is too many different names and many specific types of treatment for other diseases.

➢ Staff in medium to large systems are many, difficult to manage, besides there will be cases where these pharmacists leave work and newStaff come back to work, it will be very difficult to manage if it happens often.

➢ Customers often buy many products at the same time. It will be tough for them if they have to wait for the staff to calculate, not to mention that a customer shop is crowded and they buy many medicinal products, they will wait a long time, and their experience at the store will not besatisfactory. they will complain about their uncomfortable experience.

Because of the above inadequacy, the store decided to create a management system to better manage its drugs and employees as well asincrease a better customer experience. Attract more new customers, increase store revenue
