Doing billing on my end, what are considered DB objects that count toward your total DB object count (and ultimately what is billed)?

Does it include literally everything or just the records model for example? Are forms, pages, partials, constants, assets etc. all counted since they also have database records?

For example:
Production 25 has 8000 DB objects

Lets say I have 20 pages, 20 partials, 100 assets

Using this query

    {%- graphql records -%}
      {
        records(per_page: 1) {
          total_entries
        }
      }
    {% endgraphql %}

It tells me I have 1,000 total entries

Have I used 1,000 of my 8,000 or have I used 1,140 (counting pages, partials, assets).... or something totally different?
