SEMANTIC DATA MODELING FOR ATM SYSTEM
AIM:
To create E-R Diagrams
ALGORITHM:
1. Semantic data models define the meaning of data within the context of its interrelationships with other data.
2. A semantic data model is an abstraction which defines how the stored symbols relate to the real world. Thus, the model must be a true representation of the real world.
3. Draw E-R diagram to represent the model of the ATM System
PROBLEM STATEMENT:
1. This system is build for the bank client and the manager.
2. The bank client must be able to deposit and withdraw amount form his/her accounts using the ATM machine. Each transaction must be recorded and the client must be able to review all transactions performed in his/her account. Recorded transactions must include the date, time, transaction type, amount and account balance after the transaction.
3. The bank manager must be able to view the ATM machine status that is the total balance of the ATM machine, today’s withdrawal, today’s balance and the limitations of the machine.
4. The bank client is provided by login verification. If it is valid he/she will access their account otherwise an appropriate message is displayed to the client.
SOFTWARE REQUIREMENTS:
E- Draw
OUTPUT:
RESULT
The use case, sequence and collaboration diagrams have been successfully drawn for ATM system using CASE tool.
