Dataset Protocol
Real-time dataset synchronization across multiple connected clients. Broadcast inserts, updates, and deletes automatically as they happen.
Real-time dataset synchronization across multiple connected clients. Broadcast inserts, updates, and deletes automatically as they happen.
Streams TDataSet changes from a server-side TDataSet to remote clients in real time. Send the initial snapshot, then push inserts / edits / deletes as they happen.
TsgcWSPClient_Dataset
TDataSet sync over a WebSocket channel
Windows, macOS, Linux, iOS, Android
Enterprise
Bind a TDataSet to the server component, bind the matching client-side TDataSet, the framework keeps them in sync.
