Toward Higher-Level Abstractions for Software Systems

Software now accounts for most of the cost of computer-based systems.
Over the past thirty years, abstraction techniques such as high level
programming languages and abstract data types have improved our
ability to develop software. However, the increasing size and
complexity of software systems have introduced new problems that are
not solved by the current techniques. These new problems involve the
system-level design of software, in which the important decisions are
concerned with the kinds of modules and subsystems to use and the way
these modules and subsystems are organized. This level of
organization, the software architecture level, requires new kinds of
abstractions. These new abstractions will capture essential
properties of major subsystems and the ways they interact.
