Summary

In this lesson, the following has been discussed:

		Large information systems must often be developed as a network of loosely coupled autonomous
		components, services (possibly information systems) integrated using peer-to-peer principle (P2PIS).

		The ability of components to be developed autonomously is the crucial qualitative property of the
		components of large systems.

		The properties of the interfaces of AC, is the basis of the requirements specifications of software
		confederations.

		The requirement specifications for confederations must often be oriented toward the use of existing systems
		and their interfaces.
