**Response object:**

* `db_name` is the name of the database you gave when you called `new PouchDB()`, and also the unique identifier for the database.
* `doc_count` is the total number of non-deleted documents in the database.
* `update_seq` is the sequence number of the database.  It starts at 0 and gets incremented every time a document is added or modified.

There are also some details you can use for debugging. These are unofficial and may change at any time:

* `adapter`: The name of the adapter being used (idb, websql, leveldb, ...).
* `idb_attachment_format`: (IndexedDB) either `'base64'` or `'binary'`, depending on whether the browser [supports binary blobs](/faq.html#data_types).
* `sqlite_plugin`: (WebSQL) true if the [SQLite Plugin][] is being used.
* `websql_encoding`: (WebSQL) either `'UTF-8'` or `'UTF-16'`, depending on the [WebSQL implementation](http://pouchdb.com/faq.html#data_types)
* `backend_adapter`: (Node.JS) the backend *DOWN adapter being used (MemDOWN, RiakDOWN, ...).
