The CData FireDAC Components for Open Exchange Rates models the Open Exchange Rates API as relational views and stored procedures.
Views and stored procedures are defined in schema files, which are simple, text-based configuration files.
Views are tables that cannot be modified. Typically, read-only data are shown as views.
Stored Procedures are function-like interfaces to Open Exchange Rates. They can be used to surface additional capabilities of the Open Exchange Rates API.
API limitations and requirements are documented in this section; you can use the SupportEnhancedSQL feature, set by default, to circumvent most of these limitations.
