A memory tag that you update just after the data is saved in the database is probably the simplest method. (I would use a datetime memory tag and write `system.date.now()` to it.) The consumers in the UI would use a tag binding on a session or view or component custom property, with a change event to perform the necessary UI operations to redisplay content (probably a `.refreshBinding()` method call where the named query resides to make it run again). The only downside to the memory tag approach is that binding evaluation will likely double-execute the query on view startup. A more complicated approach that avoids that problem would be to broadcast a message after saving in the database, and having message handlers cause the content redisplay. Take a close look at this topic, and the behavioral differences between `system.util.sendMessage()` and `system.perspective.sendMessage()` in regards to gateway scope broadcasts: > [@system.perspective.sendMessage() function](https://forum.inductiveautomation.com/t/system-perspective-sendmessage-function/73047): > > Has anyone been able to use the system.perspective.sendMessage() function when it is triggered by a tag change event?
