E-R diagram and Database Implementation

A) In the given Entity-Relationship diagram, there are four main entities Customer, Branch, Transaction and Account. The purpose depicted from this ER diagram is: It shows the operations of a banking database application where various customers has their accounts. The customer has been given an id which is the unique identification of the customer. The customer can have their account in various branches of the same bank. Every branch has its own unique code and a name. A distinct account number is provided to every customer that holds their private transactions such as Account Type and Balance. All the transactions made by the bank customers are recorded in the bank database and every single transaction made by any of the customer possesses a unique identification number. The date and type of transaction is recorded and if it is monetary transaction then amount used is also recorded in the database. In brief it depicts that, a customer has an account in some branch of the given bank and performs transaction on his account which all gets recorded in database.

B. The database has been created using MS ACCESS and the database has been named as OrientalBank. All the four tables were created with the desired fields and same has been shown thorugh screenshots using snippin tool:

C. Following are the screenshots of the 4 tables after entering 10 data records in each table:

Other than these four tables it was necessary to create three other tables that will allow joining the data and those are as follows:

D.  The report cards that can be generated using Oriental Bank Database are:

  • List the name of customers those who have only savings account in branch Sydney
  • List all the branches of Oriental Bank
  • List all the customers of Oriental Bank who have an account in Adelaide branch
  • List all the transactions occurred on a particular date.
E. Customer (CID, CNAME)

Branch (BCODE, BNAME)

Account (ANO, ATYPE, BALANCE)

Transaction (TID, TTYPE, TDATE, TAMOUNT)

F. A primary key column (either a single column or combination of 2 or more columns) is a distinctive column in a relational database which is designated to contain uniquely identifiable records. The main feature of a primary key is to consist of a unique value for every row of data present. And there cannot be any null values for the primary key column.

The primary keys for OrientalBank database are:

  • cid for Customer Table
  • bcode for Branch Table
  • ano for Account Table
  • tid for Transaction Table
A. Please refer Task 1 (B) and (C) for the answer of this question.

B. SELECT Account.BALANCE

FROM Account

WHERE (((Account.BALANCE)>500));

SELECT Customer.CNAME

FROM Customer, CustomerBranchAccountDetails AS D, Account AS A

WHERE (Customer.CID = D.CID and D.ANO=A.ANO and A.balance>(SELECT AVG(BALANCE) FROM Account));

SQL View for the query:

SELECT C.CID, C.CNAME, T.TID, T.TDATE, T.TTYPE  

FROM Customer C, Transaction T, CustomerTransactionRecord R WHERE (C.CID=R.CID and R.TID=T.TID and C.CID=(SELECT CID FROM CustomerBranchAccountDetails D, Account A where D.ANO=A.ANO

SQL View for the query:

SELECT C.CID,C.CNAME

FROM Customer C,CustomerBranchDetails D

WHERE C.CID=D.CID and D.BCODE= (SELECT BCODE FROM BRANCH WHERE BCODE=102);

Result:

SELECT *

FROM Customer;

Result:

FROM Account;

Select A.ANO, C.CNAME

From Account A, Customer C, CustomerBranchAccountDetails D

WHERE C.CID=D.CID and D.ANO=A.ANO and A.BALANCE<1000 and D.BCODE=(SELECT BCODE FROM BRANCH WHERE BCODE=102);

Result:

Select C.CID, C.CNAME

From Account A, Customer C, CustomerBranchAccountDetails D

WHERE C.CID=D.CID and D.ANO=A.ANO and

A.BALANCE<1000 or (D.BCODE=(SELECT BCODE FROM BRANCH WHERE BCODE=102));

Select C.CID, C.CNAME

From Customer C, Branch B, CustomerBranchDetails D

WHERE C.CID=D.CID and D.BCODE=B.BCODE

and B.BNAME="MELBOURNE";

Select SUM(BALANCE)

FROM Account;

Result:
