@izadmehr The readme explains it here:
https://github.com/nolanlawson/relational-pouch#dbrelmakedocidparsedid
It provides a natural sort order for keys.
On reason it is useful is that you can easily determine min and max keys for a particular document type, which can be used as startkey/endkey on Batch Fetch and Query
Here's some example code determining min and max keys for an object type of "person":
var minId = db.rel.makeDocID({ "type": "person");
var maxId = = db.rel.makeDocID({ "type": "person", "id": {});
This would produce a minId of person_0 and a maxId of person_3 which according to sort order would make min id less than a id of number or string (eg less than person_1_0000000000000123 or person_2_onetwothree) and the max id would be greater than these ids.
Does that make sense?

Thanks for your answer @jkleinsc. I'm working on syncing pouchDB with couchBase, so data added to couchBase & used in PouchDB. I think this id generator is not necessary. Just adding prefix with underline, do the work.
