title: Is there a term to describe tables where only the last value should be used?
body: <p>In my database there are tables where each row represents an entity, and there are other tables where the same entity can appear multiple times, but only the latest entry is the valid one.</p>
  
  <p>For example, I have a table <code>customer</code> where each row represents a customer and another table <code>customer_membership_status</code> where the same customer can be referenced multiple times, but only the last record for each customer is suppost to be used. Data is never updated in <code>customer_membership_status</code>, only inserted.</p>
  
  <p>Is there a term to describe this pattern? I'm asking because I would like to quickly and easily explain the intended use of the table to others.</p>
