Chapter 1: INTRODUCTION

1 About the Organization

Truong Ha fashion shop was first introduced and open for business 2 years ago, most of the store’s products include clothing and sometimes jewelry, but the jewelry business of the shop was not a success so there will be no data whatsoever included in the system The operation of the store is rather simple, the manager buys items from a trustworthy wholesale partner in China and then puts a tracking and authentication tag for after service and to prove that item is a high-quality item from our store afterward, the items will be sold to the customer in Vietnam’s region The business also includes collaboration with a certain shipping company

It was not hard to figure out the database system of the shop since the owner was a very good friend of mine and our team had 3 types of investigation made to clarify the data which afterward used by us to build up parts of this final examination

i —s Interview

We spent 2 hours every day for a whole week to interview the owner of the shop, we asked about where the source of her products was, how was that product made, if it was good to use and if it was from trustworthy and high-quality factures and suppliers

After investigating all about the origin and how the items were made,

me conducted research on the shop’s Facebook page ad website to find out the way they handle their business with customer, or to be exact, how did they sell their items and if the customer come to the shop directly to buy the items or they buy them online and have them delivered to their house

We found out that the shop is now working only on online platforms since the pandemic brought up a very big safety issue, they decided to close the physical shop until the working environment is safer, this is when we

inspect their shipping collaboration more carefully and put it in our database

After looking at the store’s online platforms and its shipping companions, we wanted to inspect further in the flow of the items, would there be any other trading activities of goods after it was bought used by the customer or not In this investigation, we found out the shop supported its clients to buy and trade theirs good after buying it by establishing a trading and reselling the store’s goods community a website and there is no shipping collaboration seen in this part, the customer can offer and deal and trade freely with the website playing the role of a midman to verify the authenticity of the product

3 Business Narrative

The first part that we consider the root of this business is the MANUFACTURER and the SUPPLIERS of the shop, without these two factors, the shop would not be able to operate, the MANUFACTURER has its name and address

to prove that this is a good and verified source of item, then the MANUFACTURER contact with its wholesale partner who will resell to the retail shop — the SUPPLIERS and each supplier will have its own number symbolize for the priority to buy better goods, which SUPPLIER have lower number in the MANUFACTURER’s list will have the better chance to buy good items Many SUPPLIERS provide many ITEMS which have authenticity code and proof of origin And through the SHOP, the ITEMS will be DELIVERED to CUSTOMERS by SHIPPERS who are bound to the SHIPPING COMPANY Afterwards, the CUSTOMERS can through the trading platform, trade the goods to 2NDCUSTOMERS

Chapter 2: ANALYZING AND DESIGNING THE DATABASE

ERD

To draw an ERD, we must first find out all the strong entities and theirs attributes, firstly the strong entities can be observed are MANUFACTURER have attribute name and address, SUPPLIERS have attribute number and phone number, ITEMS have attribute code and origin, SHIPPING COMPANY have attribute shipping code and delivery code, CUSTOMERS have attribute name, address and phone number and finally 2ND CUSTOMERS have attribute name, address and phone number For the part of relationships between them, MANUFACTURER to SUPPLIERS will be one must to maybe many since there must be manufacturer as the source and that source may sell to many suppliers and for the rest of the strong entities, the relationships between them all are many maybe to many maybe since many suppliers provide many items and those items may be shipped to many customers by many shipping company such as GHTK or Be or Extra Shipping and so on and many customers can also trade to many second customers

After expanding the ERD, we can see some more weak entities added in between all the many to many relationships first we have the SHOP weak entities after the expansion of suppliers and items many to many relationships since supplier have to go through shop and the shop will sell items, the shop entity has attribute is its name Followed by the expansion of shipping company and items many to many relationships is the appearance of the weak entity DELIVER since items must be delivered to the shipping company in order to be shipped to the customers, this leads to the appearance of weak entity SHIPPER when expanding many to many relationships of shipping company and customer

Relational Schema

-Firstly, we will list, select the filter information that must be given

-Next, we define the files and relationships between the implementation collectives

-For example, in my ERD, we have:

One MANUFACTURER can have a lot of SUPPLIERS

From SUPPLIERS we can add more unimportant entity is weak entity - SHOP One SUPPLIERS and One ITEMS can have a lot of SHOP

From ITEMS we can add more unimportant entities that are weak entities -

DELIVER

One ITEMS may have a lot of DELIVER

One SHIPPER may have a lot of DELIVER

From SHIPPER we can add more unimportant entity is weak entity - SHIPPING

COMPANY

One SHIPPER may have a lot of SHIPPING COMPANY

One CUSTOMER may have a lot of SHIPPING COMPANY

From CUSTOMER we can add more unimportant entity is weak entity -

RESELLER

One CUSTOMER may have a lot of TRADING

2NDCUSTOMER may have a lot of TRADING

-The next step is to define attributes like primary key, foreign key and bind the attribute for the file and relationship

-For example, in my ERD, we have:

Primary key:

Primary Key

(Manufacturer_Name) Primary

Key (Supplier_Number)

Primary Key (Item_Code)

Primary Key (Shipping Code)

Primary Key (Customer_Name)

Primary Key (Second_Customer_Name)

Forgein key:

Foreign Key (Manufacturer_Name) references SUPPLIERS

Foreign Key (Item_Code) references ITEMS

Foreign Key (Supplier_Number) references SUPPLIERS

Foreign Key (Shipping Code) references

SHIPPING_COMPANY Foreign Key (Customer_Name)

references CUSTOMER

Foreign Key (Second_Customer_Name) references SECOND_CUSTOMER Finally, draw an ERD diagram that identifies the type associations of the jobs performed in the schema
