title: Best Practice Updating DB Records
body: <p>Say you retrieve 100 records, and display them on a page. The user only updates 2 of the records on the page. Now you want to update only the two records, and not the other 98.</p>
  
  <p>Is it best to have one submit on the page, then somehow know which 2 are updated, then send only those two to the db for an update?</p>
  
  <p>What does the "somehow" look like?</p>
  
  <p>Or, would you have an update-submit button for each row, and have it only update the record its tied to?</p>
