- Using MySQL Workbench, Create a database named “bank” with the following tables: Customer with filds: customer_id (integer) name (string) Account with fields: account_id (integer) balance (float) type (one of ‘savings’, ‘checking’, ‘cd’) Customer_Account id (integer) cust_id (integer) acc_id (integer) Populate the database with data of your choice. Note 1: Export the database into a self-contained file named bank1.sql before you continue. Note 2: Using Apache NetBeans, create a Java project that connects to the bank database.Answer the following prompts 1The InstantRide Management team founded a new team for car maintenance. The new team is responsible for the small maintenance operations for the cars in the InstantRide system. The main idea is to take actions faster and minimize the time spent for the maintenance. Therefore, the Car Maintenance team wants to store MAINTENANCE_TYPE_ID (char(5)) and a MAINTENANCE_TYPE_DESCRIPTION (varchar(30)) in the database. Using MAINTENANCE_TYPE_ID as the PRIMARY KEY, create a new table, MAINTENANCE_TYPES, and send the table description with the column names and types to the Car Maintenance team. 2The Car Maintenance team also wants to store the actual maintenance operations in the database. The team wants to start with a table to store CAR_ID (CHAR(5)), MAINTENANCE_TYPE_ID (CHAR(5)) and MAINTENANCE_DUE (DATE) date for the operation. Create a new table named MAINTENANCES. The PRIMARY_KEY should be the combination of the three fields.
