best way to add Entity id & entity types in database we are doing shopping site with mysql with eav model to store values.

in below image , 2 types of entity types are there under products_information table : 1) Mobile 2) T-shirts

I wanted to know in which table i have to store those entity types &amp; entity ids

Is i need to create new table or adding above 2 columns in existing table ?
Make "Entity" an entry in attributes_list and treat it as any other attribute.

Also, do the same for "Category" (whatever your categories might be) and drop Category_details table
