1.4. Performance

Indexes

  • Ensure indexes on columns used in WHERE, ON, GROUP BY clauses
  • Always ensure JOIN conditions are indexed (and have identical data types)
  • Be careful of the column order
  • If you don't pick a primary key (bad idea!), one will be created for you -> And, you have no control over the key

1.5. Naming

Use singular for table names, e.g. “page” not “pages”
A table structure describes a specific entity
