large software system	cannot be understood by one person
	has requirements document for a large system
	is hard to understand
	is a subtopic of 1.2 - What is Software Engineering?
	is a kind of software system
	must be developed by a software development team
	must be developed using engineering discipline
	requires a software architecture^3
software system	becomes complex because it is easy to add new features and because software engineers typically add features without fully understanding a system, which may not have been originally designed to accommodate the features
	can automate business process
	can be divided in many ways: A distributed system is divided up into clients and servers A system is divided up into subsystems A class is divided up into methods
	is typically initially developed as a prototype
	should be designed for flexibility right from the start
	undergoes evolution over its life-span
system	can have specification which is then implemented by a collection of components
	exists even if its components change over the course of time, or are replaced by equivalent components
	has scope
	has part component
	has part hardware
	has part module
	has part software
	has part subsystem
	is divided up into subsystems
