  1. Database Programming with FireDAC Bob Swart(aka “Dr.Bob”) Bob Swart Training & Consultancy (eBob42) www.eBob42.com Delphi Benelux 2016 Congress 26 May 2016, Eindhoven http://www.eBob42.comBob@eBob42.com

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

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

  4. 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 http://www.eBob42.comBob@eBob42.com

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

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

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

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

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

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

  11. 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 http://www.eBob42.comBob@eBob42.com

  12. Questions • Bob@eBob42.com • http://www.eBob42.com • ebob42 and drbob42 • http://facebook.com/drbob42 • http://twitter.com/eBob42 • http://nl.linkedin.com/in/drbob42 http://www.eBob42.comBob@eBob42.com
