At the user level, system data is accessed through form lists and by viewing individual form records; at the data-flow level it is accessed through
API interfaces: in formula design that follows the data flow, data is mainly passed through data interfaces.
An API data interface is defined with parameters, corresponding to the way database views (view) are designed in traditional system development;
interface definitions on this platform are fully compatible with all kinds of SQL keywords and functions.
Flexibly defining and using API interfaces enables efficient access to all kinds of data and the development of statistical and analytical reports.
