Sencha Ext JS Web App from GetIt In C++Builder 10.2.2, Embarcadero has added a new component to the FireDAC BatchMove architecture, to support generating JSON data from database tables, in an easy and flexible way. RAD Studio (Delphi and C++ Builder) has offered support for JSON in different ways and for a long time. From the JSON system unit (originally part of the DBX space) to the DataSnap table mapping (also via DBX) and to FireDAC tables to JSON mapping, there are many ways to interact with JSON data structures. As an enhancement, in the 10.2.2 release, we now added the capability to map a dataset to a custom JSON structure -- the FireDAC JSON support produces a FireDAC specific structure,metadataa data, and record status information.
