Where is Ticker Text Stored

The easier/better way of going about this would be to use the built-in filters and just populate the ticks through php as opposed to trying to modify the database (which I don’t have any suggestions on accomplishing this). Here’s a starting point (add to either your theme’s funtions.php file, or a build a custom plugin to run the code):

function my_custom_ticks( $ticks, $id, $meta_data ) {

	if( $id == 555 ) {

		$new_ticks = array();

		// Use your php here to create an array of data (each array item is a "tick").

		// Return the new ticks
		return $new_ticks;
	}

	return $ticks;
}
add_filter( 'mtphr_dnt_tick_array', 'my_custom_ticks', 10, 3 );

You would need to create a ticker in your dashboard, but you wouldn’t have to actually create any ticks for it as the code above would be used to populate the ticker. Be sure to change the “555” to the post ID of your ticker.
