The Environment Architecture group addressed the nature and roles of an architecture for a software engineering environment and how a next generation environment might look. An architecture can be thought of a number of different ways including as:• The accumulated information on the high level design• A set of descriptions, renditions, or views• What was decided first in designing the environment• A document addressing "architectural" issues.All of these have some merit when one considers the main uses of an architectural description. It is a record of design decisions, an aid in understanding the environment, an aid in evaluation and comparison of environemnts, and serves the needs of different audience --- primerily the architect, the user, and the tool builder.
