Database Structure

All posts

• The posts category contains every post made in history. It is organized as a dictionary identified by a unique key (post-id), and each post contains a dictionary with the following structure: [“author”, “body”, “starCount”, “title”, “uid”, “userIDsStarredBy”]
• The unique keys (post-ids) are generalized as posts are created, sorting them would yield a list of posts from most to least recent.
• Example:

Comments on each post

• The post-comments category organizes every comment on each post. It starts with a dictionary of posts identified by a unique key (post-id), each post is composed of a list of comments identified by another unique key (comment-id), and each comment contains a dictionary with [“author”, “text”, “uid”].
• Comment-ids are generalized as comments are sent, sorting them would yield a list of comments from most to least recent.
• Example:

Posts grouped by users

• The user-posts category is a list of posts organized by “uid” (user-ids) that are unique to each user.
• Since the posts are grouped by users, it is easy to fetch and sort posts from a single user.
