View Full Version : Simple Banking database
12-31-2011, 08:23 PM
I have to create a simple bank database using MySQL, so i have to create tables and relationships between them (normalization).
I have created those tables :
Branch (BranchID, BranchPlace)
Account (AccountID, AccountNumber, AccountType, Balance)
Client (ClientID, ClientName, ClientSurname, ClientCity)
Transaction (TransactionID, TransactionType, Amount)
So i need defining primary keys and foreign keys, can anyone help me with this ?

I created those tables, but i think i should relate table Client with another table , what would u suggest .
create table Branch (
Primary key (BranchID)
create table Account (
Foreign key(BranchID) references Branch(BranchID)
create table Client(
primary key (ClientID)
create table transaction(
primary key (TransID),
foreign key (AccountID) references account (AccountID)

You could relate client to branch, as most banks assign a client to a single branch, but from a database standpoint that's not needed.
If you do it, just add
Branch ID INT REFERENECES Branch(BranchID)
to the clients table.
