+Framework and tech debt
+	# build extensible CLI framework
+
+		commands.json maps command names to command class names. Command classes must
+		implement command interface and provide execute method, which CLI framework calls.
+
+		Each command calls to service layer, and service layer interacts with the ORM.
+	# Collections do filtered queries:
+		given attribute, comparison type (less than, equal to, and greater than), and comparisonValue
+
+		(also possible with activeRecord model, coupled to DB, if expose setId publicly or 
+		as package private).
+
+	# Use builders, repositories, and collections?
+
+		Client only uses repository, collection. Client cannot change entity ID.
+
+		ID is set in constructor only: if you provide ID in constructor, you must also
+		provide every other value so that object is immediately saveable. Constructor only
+		called by builder, builder only called by repository and collection.
+
+		Entity has two constructors: empty and with all attributes included.
