Answer 1

Use a ScheduledService.
The basic idea is
ScheduledService<ObservableList<MyTableDataType>> databasePollingService = new ScheduledService<ObservableList<MyTableDataType>>() {
  @Override
  public Task<ObservableList<MyTableDataType>> createTask() {
      return new Task<ObservableList<MyTableDataType>>() {
          @Override
            public ObservableList<MyTableDataType> call() throws Exception {
                // connect to database and return list of data....
databasePollingService.setPeriod(Duration.seconds(POLLING_TIME));;
TableView<MyTableDataType> table = new TableView<>();
// configure table etc....
table.itemsProperty().bind(databasePollingService.lastValueProperty());
databasePollingService.start();
