The National Bank of Erehwon handles money and maintains bank accounts on behalf of clients. A client is a person who does business with the bank. A client may have any number of accounts, and an account may belong to multiple clients (e.g., spouses, business partners). The client record is used for identification and contact data. For each account, the bank maintains the current balance on hand. Clients are identified by a five digit number starting with 10001. Accounts are identified by a seven digit number starting with 1000001. When an account is first opened, its balance is set to zero. During the course of day-to-day business, Erehwon Bank applies transactions to accounts, including deposits, withdrawals, bill payments, and debit purchases or returns. For each transaction, the date and time, amount, and account are recorded, along with reference data applicable to that type of transaction: Deposits and withdrawals require the branch number to be recorded. Bill payments, and debit purchases or returns require the merchant number. Building and Populating the Schema Develop a database in Oracle to implement the Erehwon Bank scenario. Populate your database with the test data. Views: To facilitate queries, three views are required. generate your SQL script(s) as well as a SELECT * FROM … listing of each view. Join of Client to Account via the Owns table, containing the client’s number, name, the account number, and balance. (Hint: Use an outer join as one client has no accounts.)
