Ask HN: How important is to invest in DB design from scratch ?
I have an app in mind that I want to implement and can possibly do with basic knowledge of a DB. Is it a good idea to go ahead and develop it and come back later to optimize the DB.
PS: Also I was having a hard time to search for a Class being mapped to a DB<p>Example:
Class Person{
String Name;
String Age;
Person myFriends[];
}<p>user_table
name | age | {myFriends[]} |<p>how do you map the myFriends[n] to a DB ?
