title: UML Sequence Diagram help needed
body: <p>I am currently stuck with creating a UML sequence diagram. The diagram will only have one Actor which is staff, staff needs to instate a member once they are informed by the member and this goes through the database as well.</p>
  
  <p>1 actor- Staff</p>
  
  <p>Classes- Library information system- Interface
           Member
           Database</p>
  
  <p>Please could you help me with the sequence diagram as I am currently stuck. </p>
  
  <p>Staff needs to add member to library system once the member has informed the staff to add him or her to to the library system.</p>
  
  <p>Then this needs to go to the database which send a return message to the staff to tell them that the member has been added.</p>
  
  <p>Only staff is talking to the system and nobody.  </p>
