What is a Statechart Diagram? Draw a statechart diagram modeling the behavior of the following bank account entity: A bank account is first created by a bank manager. The customer owning the account has to activate the account within one month, otherwise, this account is automatically cancelled. Once activated, the customer can use the account to perform bank transactions. The account becomes blocked for security reasons or if it is dormant for more than six months. In either case, the customer is asked to contact the bank. After being blocked for two weeks, if the customer does not contact the bank, the account is cancelled. The customer can cancel the account at any time while it is active.
