If you have code that looks like the preceding one, you are in contravention of the SRP. The StarShip class is no longer responsible for just itself and things that have to do with star ships. It now has to fulfill the role of logging errors to the database too. You see the problem here is that the database-logging code does not belong in the catch clause of the SetMaximumTroopCapacity method. A better approach would be to create a separate DatabaseLogging class with methods to create connections and write exceptions to the appropriate log table. You will also find that you are going to have to write that logging code in multiple places (in every catch clause). If you are finding that you are repeating code (by copying and pasting from other areas), you probably need to put that code into a common class, and you have likely broken the SRP rule.
