Example of CRC cards
Let’s understand CRC Cards using example of banking system.
1. Class: Account
Responsibilities:
- Store account holder information (name, address, contact details).
- Maintain account balance.
- Perform transactions (deposit, withdrawal).
- Generate account statements.
Collaborations:
- Collaborates with Transaction class for performing deposit and withdrawal operations.
- Collaborates with Statement class to generate account statements.
2. Class: Transaction
Responsibilities:
- Record transaction details (date, type, amount).
- Update account balance based on deposit or withdrawal operations.
Collaborations:
- Collaborates with Account class to perform deposit and withdrawal operations.
3. Class: Statement
Responsibilities:
- Generate account statements for a specified period.
- Include transaction details (date, type, amount) in the statement.
