The overall objective of this project was to create a fullyfunctional database system for a online bank.

The database should allow the introduction of newcustomers along with allowing existing customers toview their account as well as obtain new productsin terms of loans and additional accounts.

To produce this database there are three main steps;Conceptual data model, Logical

data model and Physical data model

Introduction

Underline Assumptions and Limitations

‘Products’ refers to all services which the bank offers

Credit card bills are generated on a monthly basis

Bank statements are generated on a quarterly basis

Each customer automatically receives a debit cardand ICT ID and password when they create anaccount with the bank

Underline Assumptions and Limitations Cont.

Query One

What is the ICT ID and Password for all thecustomers with the surname Doyle?

Query Two

What is the sum of all transactions which have beencarried out by Mr. O’ Connor?

On completion of this project we have learned

extensively about the different stages involved when creating a database system.

One of the key learning outcomes we received from completing this database system is that before one can continue on to the next stage of the project you must first ensure the previous stage is correct, if not this will only cause errors in future stages.
