Social network business use case

This use case talks about using DynamoDB as a social network. A social network is an online service that lets different users interact with each other. The social network we'll design will let the user see a timeline consisting of their posts, their followers, who they are following, and the posts written by who they are following. The access patterns for this schema design are:

• Get user information for a given userID

• Get follower list for a given userID

• Get following list for a given userID

• Get post list for a given userID

• Get user list who likes the post for a given postID

• Get the like count for a given postID

• Get the timeline for a given userID
