What is Quandl's nomenclature system for data?
Each database on Quandl has a short (3-to-6 character) database ID. For example:
- CFTC Commitment of Traders Data: CFTC
- Core US Stock Fundamentals: SF1
- Federal Reserve Economic Data: FRED
Each database contains many datasets. Datasets have their own IDs which are appended to their parent database ID, like this:
- Commitment of traders for wheat: CFTC/W_F_ALL
- Market capitalization for Apple: SF1/AAPL_MARKETCAP
- US civilian unemployment rate: FRED/UNRATE
You can jump directly to any database page on Quandl by going to www.quandl.com/DATABASE_ID. For example, you can jump directly to the CFTC Commitment of Traders database by going to www.quandl.com/CFTC.
Similarly, you can jump directly to any dataset page on Quandl by going to www.quandl.com/DATABASE_ID/DATASET_ID. For example, you can jump directly to the dataset for Commitment traders for wheat by going to www.quandl.com/CFTC/W_F_ALL.
Database and dataset IDs are sometimes also referred to as Quandl Codes.
Note that dataset IDs are not guaranteed to be unique across databases. For example, SHFE/CUG2014 is not the same as MCX/CUG2014. Thus, you need both the database code and the dataset code to go directly to a dataset.
