Data Management with SQL for Ecologists: Discussion

Proposed Episode on Database Design

Q & A on Database Design (review if time)

  1. Order doesn’t matter
  2. Every row-column combination contains a single atomic value, i.e., not containing parts we might want to work with separately.
  3. One field per type of information
  4. No redundant information
    • Split into separate tables with one table per class of information
    • Needs an identifier in common between tables – shared column - to reconnect (foreign key).
