Basic concepts of normalizing data:
- Each type of data gets its own “table” in the state.
- Each “data table” should store the individual items in an object, with the IDs of the items as keys and the items themselves as the values.
- Any references to individual items should be done by storing the item’s ID.
- Arrays of IDs should be used to indicate ordering.
- Use “Normalizr” library if you want to automate the normalization process
