2. http://www.eBob42.com Bob@eBob42.com Agenda FireDAC Architecture Monitoring and Tracing Cached Updates TFDMemTable Local SQL Migration from BDE, ADO, DBX (DataSnap)

3. http://www.eBob42.com Bob@eBob42.com FireDAC Architecture Universal Data Access Components TFDManager, TFDConnection TFDQuery, TFDTable, TFDStoredProc TFDMemTable TFDLocalSQL TFDPhysxxxDriverLink TFDGUIxWaitCursor

4. http://www.eBob42.com Bob@eBob42.com Monitoring and Tracing Monitoring DBMS connection (real-time) –FireDAC Monitor (tools menu) Tracing between FD and DBMS (log) –TFDMoniFlatFile/Remote/CustomClientLink EventKinds, ShowTraces, Tracing Remote  FDMonitor Custom  OnOutput event handler –TFDConnection.Params.MonitorBy

5. http://www.eBob42.com Bob@eBob42.com Cached Updates CachedUpdates = True –ChangeCount, Undo options –CancelUpdates / Apply/CommitUpdates UpdateOptions –UpdateMode –RefreshMode

6. http://www.eBob42.com Bob@eBob42.com TFDMemTable In-memory datasets –Can contain multiple datasets! Successor of TClientDataSet –No requirement for MIDAS.DLL or MidasLib Useful in DataSnap applications

7. http://www.eBob42.com Bob@eBob42.com Local SQL TFDLocalSQL Uses SQLite driver –TFDConnection, DriverName = SQLite –TFDPhysSQLiteDriverLink Useful for combining tables from heterogeneous databases!

8. http://www.eBob42.com Bob@eBob42.com Migration to FireDAC BDE Migration –TSession  TFDManager –TDatabase  TFDConnection –TQuery  TFDQuery –TSortedProc  TFDStoredProc –TTable  TFDTable

9. http://www.eBob42.com Bob@eBob42.com Migration to FireDAC ADO Migration –TADOConnection  TFDConnection –TADOQuery  TFDQuery –TADOSortedProc  TFDStoredProc –TADOTable  TFDTable Not really necessary

10. http://www.eBob42.com Bob@eBob42.com Migration to FireDAC dbExpress Migration –TSQLConnection  TFDConnection –TSQLQuery  TFDQuery –TSQLSortedProc  TFDStoredProc –TSQLTable  TFDTabe –Need no TDataSetProvider + TClientDataSet is

11. http://www.eBob42.com Bob@eBob42.com Migration to FireDAC dbExpress DataSnap Migration –TSQLConnection  TDSRestConnection –TClientDataSet  TFDMemTabe –No IAppServer interface (normal data mod) –No TDataSetProvder (server side) –No TDSProviderConnection (client side) is
