Relational Database
-------------------

`draft` `optional`

This NIP offers a plug-and-play method to export/sync information from existing systems using relational databases into Nostr. 

Event kind `31200` represents a row in a database. Each value of the row is added as a tag whose name is the column's name. 

The `d` tag is used for the row's primary key, the `n` tag places the row into an unbound list and the optional `u` tag references a database name. 

Values can be public or encrypted to the user. 

```js
{
  "kind": 31200,
  "tags": [
    ["d", "<row-primary-key>"]
    ["n", "<table-name>"]
    ["u", "<database-name>"]
    ["<column-name>", "<column-row-value>"]
    // other public columns
  ],
  "content": nip44Encrypt(JSON.stringify((
    [
      ["<column-name>", "<column-row-value>"]
      // other private columns
    ]
  )),
  // .. other fields
}
```

Inserts and updates are supported via Nostr's regular signing operations and deletions via [NIP-09](09.md).

The pubkey MAY be own by the system and represent several users from that system.
