Parse.com android relationship

Question

I am using parse.com for my app. I need help to solve this scenario. I have two tables say

category table

with n number of category and

product table

with n number of products. Now how can i set the relation between category and products. A product may comes in more than one category. Say productX may comes under categoryA and also categoryB. Should i use pointer or relation. Can any one provide a good example.

Thanks in advance.

Answer 1

For almost all your relationships, a pointer is all you need. However, a pointer column can only include 1 objectId, so in your case you need to create the column as an array, and store pointers in the array.
