DataManagement
Everything about where data lives and how it's accessed — pre-existing folder with Storage/Database/DataEng already started.
Why we need this / what value this brings
How data is stored, cached, and accessed shapes almost every other part of system performance and correctness.
When to use this
Foundational — get the core schema and access patterns right early since they're expensive to change once data has accumulated.
How to use or implement this
Design the schema around actual query patterns (see Database/), and add caching only once a specific read is measurably slow.
