[Question] Does it fit my use case?

[Extarys]

Discovered this on Twitter ! :O

Now, I'm asking this because I never used an ORM before and would like to optimize this to reduce both database load and disk usage/space.

I want to use routing-controllers and socketio to send realtime data for some stats.
(Still trying to figure out how to make r available in my controllers though)

Example 1
Table Heroes: (~100 records)
hero_id, name, stat1, stat2, stat3, created_at, updated_at, version, abils

Table Abilities (belongs to Hero) (~1000 records, each hero may have between 1 and 30 abilities for example)
abil_id, hero_id, name, desc, dmg, recover, mod, ...

Table Upgrade (belongs to one or mulitple abilities)(~4000 records, each hero and/or ability may have between 1 and 30 upgrade for example)
up_id, name, desc....

Will this store 'Upgrade' elements in both an Upgrade table and a sub-doucment of the parent hero or ability.

Example 2:
I grab data from a website that doesnt support API and want to cache as much as possible to reduce the bandwidth/requests made to this site.

Table Players: (~500 players)
player_id, player_name, last_update

Table PlayerStats: (~alot, 1 document per player every 6 hours or so)
player_id, stat_id, created_at, kills, death, orb, gems, time, hero_id, ...

I would like to get all kills for a player, or the global average kill per hero.

Thanks for taking the time! <3
