  22  * Here are described all the tables, fields and indexes Friendica needs to work.

  24  *
  25  * Syntax (braces indicate optionale values):
  26  * "<table name>" => [
  27  *      "comment" => "Description of the table",
  28  *      "fields" => [
  29  *              "<field name>" => [
  30  *                      "type" => "<field type>{(<field size>)} <unsigned>",
  31  *                      "not null" => 0|1,
  32  *                      {"extra" => "auto_increment",}
  33  *                      {"default" => "<default value>",}
  34  *                      {"default" => NULL_DATE,} (for datetime fields)
  35  *                      {"primary" => "1",}
  36  *                      {"foreign|relation" => ["<foreign key table name>" => "<foreign key field name>"],}

  47  *
  48  * Whenever possible prefer "foreign" before "relation" with the foreign keys.
  49  * "foreign" adds true foreign keys on the database level, while "relation" is just an indicator of a table relation without any consequences
  50  *
  51  * If you need to make any change, make sure to increment the DB_UPDATE_VERSION constant value below.
