2.7 Data contracts
We will touch on data contracts at various stages in this pipeline. This application’s data acquisition, for example, may have a formalized contract with a data provider. It’s also possible that an informal data contract, in the form of a schema definition, or an API is all that’s available.
In Chapter 8, Project 2.5: Schema and Metadata we’ll consider some schema publication concerns. In Chapter 11, Project 3.7: Interim Data Persistence we’ll consider the schema provided to downstream applications. These two topics are related to a formal data contract, but this book won’t delve deeply into data contracts, how they’re created, or how they might be used.
