Woocommerce plugin database

I am new at woocommerce plugin. I just installed woocommerce plugin by wootheme. Now i want to know what kinds of datas are stored in woocommerce plugin database. So i can input/push custom data into them.

Like i came to know after installing woocommerce plugin, 9 custom tables are created in my wordpress database. They are woocommerce_attribute_taxonomies,woocommerce_termmeta, woocommerce_downloadable_product_permissions, woocommerce_order_items, woocommerce_order_itemmeta, woocommerce_tax_rates, woocommerce_tax_rate_locations, woocommerce_api_keys, wp_woocommerce_downloadable_product_permissions

Now i want to know what types of datas are stored into those tables. I can figure out by seeing each tables but i am afraid of missing some of data types.

That's why i am asking for help so that i can have complete data types stored into woocommerce database.
