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>"],}
37  *                      "comment" => "Description of the fields"
38  *              ],

41  *      "indexes" => [

44  *              ...
45  *      ],
46  * ],
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.
