How is the data implemented?

Q. How does oik-types implement the data for CPTs, taxonomies and relationships?
A. It records the information in structured arrays on the wp_options table.

• bw_types contains the manually defined custom post types
• bw_fields contains the manually defined custom fields
• bw_f2ts contains the Fields to Types relationships
• bw_x2ts contains the Taxonomies to Types relationships

oik-types does not create any tables of its own.

• Each instance of a custom post type is created in the wp_posts table
• Each instance of a custom field for a custom post type is created in the wp_postmeta table
• Each instance of a custom taxonomy is created in the wp_taxonomy and related tables
