As mentioned in Chapter 2, this guide lays out a framework for navigating the diverse
world of data content centered on two primary classes of content:
1. Reference data
2. Business data.
The term ‘reference data’ takes on a very precise definition within this guide as a sub-
set of the overall universe of market data:
Reference data is a collection of facts that describe an issuer, a financial
instrument, or a market quote and their associated interrelationships.
