relationships between the classes:<\/p>\n<ol>\n<li><strong>ATM to Transaction<\/strong>: The ATM processes transactions, indicating a clear association between the ATM and Transaction classes.<\/li>\n<li><strong>Transaction to User and Account<\/strong>: Each transaction is related to a user and affects a specific account.<\/li>\n<li><strong>Card to User<\/strong>: The card has a direct relationship with the user, as it is associated with their account.<\/li>\n<\/ol>\n<h3>Explanation of the Relationships<\/h3>\n<ul>\n<li><strong>ATM to Transaction<\/strong>: The ATM can process multiple transactions, indicating it initiates and manages these transactions.<\/li>\n<li><strong>Transaction to User<\/strong>: Each transaction is initiated by a user, establishing a direct link between the transaction and the user requesting it.<\/li>\n<li><strong>Transaction to Account<\/strong>: Each transaction affects a specific account, demonstrating how transactions impact the user&#8217;s bank account.<\/li>\n<li><strong>User to Card<\/strong>: A user can own multiple cards, maintaining a direct relationship between the user and their cards.<\/li>\n<\/ul>\n<h2>Step 4:
