Database structures

+
    +
  1. Every table must have an auto-incrementing id field (INT(10)) as primary index.
    2. +
  2. The main table containing instances of each module must have the same name as the module (eg widget)
    3. +
  3. Other tables associated with a module that contain information about 'things' should be named widget_things (note the plural)
    4. +
  4. Column names should be simple and short, following the same rules as for variable names.
    5. +
  5. Columns that contain a reference to the id field of another table (eg widget) should be called widgetid.
    6. +
  6. Boolean fields should be implemented as small integer fields (eg INT(4)) containing 0 or 1, to allow for later expansion of values if necessary.
    7. +
  7. Most tables should have a timemodified field (INT(10) which is updated with a current timestamp obtained with the PHP time() function.
