Access er diagram. I just went from a USG + CloudKey + Ubity PoE Switch to UDM SE last night. Since the UDM has a PoE switch built in I eliminated the switch and plugged in the devices to the same numbered ports on the UDM from the switch. Everything is working ok as far as I can tell, but one of the access points is showing at the same level as the UDM SE vs behind it in the network diagram. I've tried to force reprovisioning on that access point and restarting it, but no change so far. Any thoughts on how to f...

Answer in Databases for Sandy #159758

Let's say I'm designing a new feature that requires adding a couple new tables, and adding some columns on existing tables in a relational DBMS. I need to create a design doc and present it to my team for a design review. Should I design the new DBMS data model directly, or should I first create an entity relationship (ER) diagram (which will later have to be translated into a DBMS data model)? It seems like the latter approach is more thorough, since we can brainstorm about the conceptual des...
