How can i save my database without loosing some data's when my computer will accedentally turn off.

scenario:

 I created 5 new records (i call my procedure(SaveDatabase) to save the new datas). after a minute i created another new record and call again my procedure(SaveDatabase) to save that new data, then i tried to TURN OFF MY COMPUTER or pull-out the plug,(experimentation for BROWNOUTS),the result is this... When i browse my data again, it was all gone. whats wrong? how will i save my data into the harddisk making it permanent, even if my application hangs or shutdown accidentally, my new data STILL be there.

this is my procedure, whats wrong with this?

procedure TfBrowseForm.SaveDatabase(TheDatabaseTable:Twwtable);
begin
  if TheDatabaseTable.CachedUpdates then
  begin
   TheDatabaseTable.ApplyUpdates;
   TheDatabaseTable.CommitUpdates;
   DataModule1.refreshTables;
   TheDatabaseTable.UpdateIndexes;
  end
  else
  begin
   TheDatabaseTable.UpdateRecord;
   TheDatabaseTable.Post;
   DataModule1.refreshTables;
   TheDatabaseTable.UpdateIndexes;
  end;
end;


(DataModule1.refreshTables) this will only refresh the tables
