4. Creating stored procedures for:
   - Entering Transaction: Withdrawal, Deposit, Transfer, Closing Account
   
   • Daily compounded interest calculation
5. Creating Triggers to automatically update the current balance of each account transaction.
6. Creating SQL reports An entity relationship model or diagram was created based on the needs, constraints and business rules of C/S Bank to ensure referential and data integrity. With the use of a SQL, a stored procedure was written that calculates any interest accrued on checking, savings or credit card accounts. A stored procedure was written that charges various maintenance fees on a monthly basis. A test database with multiple sets of sample data was loaded into the system to insure proper function. One such set of sample data was purposefully populated with data outside the constraints developed by C/S Bank to ensure proper data integrity and normalization of the first three levels were achieved.
