Some database trade-offs

Accessibility v security
  • a totally inaccessible database is totally secure
  • a database totally accessible to one & all is totally insecure

Reliability v accessibility

  • Who decides what is accurate? [What is your name, Cherie Blair? Nicky Campbell? Cary Grant? Peachesandcream Zola Minerva Monteverdi Cholmondely-Smyth?]
  • Who is responsible for checking the accuracy of the database
  • Who has access to correct mistakes

Timeliness v accuracy

  • How to ensure that whoever accesses the database, whenever & wherever they access it, will see the most up-to-date information
  • What happens if information is corrected/updated while I am looking at a screen
  • can we flash important information - STOP THIEF
