The Importance of Models § A large part of the RUP focuses on modeling. § Models help us understand both the: § problem and § solution. § The model is not the reality but best models are ones that stick very close to reality 2

Architecture Suppose the task: describing a system so that designers, programmers, users, and managers would be able to do the following: § Understand what the system does § Understand how the system works § Be able to work on one piece of the system § Extend the system § Reuse part of the system to build another one 3

Architecture Multiple Views For a building, different types of blueprints are used to represent different aspects of the architecture: § Floor plans § Elevations § Electrical cabling § Water pipes, central heating, and ventilation § The look of the building in its environment (in sketches) 4

The 4+1 View Model of Architecture 5

The 4+1 View Model of Architecture 1) The Logical View § It is an abstraction of the design model and identifies: § major design packages/subsystems, and § classes 6

The 4+1 View Model of Architecture 7

The 4+1 View Model of Architecture 2) The Implementation View § It addresses the issues of § ease of development, § management of software assets, § reuse 8

The 4+1 View Model of Architecture 3) The Process View § This view illustrates the process decomposition of the system, including the mapping of classes and subsystems on to processes and threads. 9

The 4+1 View Model of Architecture 10

The 4+1 View Model of Architecture 4) The Deployment View § Addresses: § how the various executables and other runtime components § are mapped to the underlying platforms or computing nodes. 11

The 4+1 View Model of Architecture 5) The Use-Case View § It contains a few key scenarios or use cases. § Initially, § are used to drive the discovery and design of the architecture in the inception and elaboration phases, § later § they will be used to validate the different views. § For example as a starting point for tests of an architecture prototype 14

An Architecture-Centric Process RUP defines two artifacts related to architecture: 1) The software architecture description (SAD), § which describes the architectural views relevant to the project 2) The architectural prototype, § which serves to validate the architecture and serves as the baseline for the rest of the development 16

An Architecture-Centric Process These two key artifacts are the roots of three others: § Design guidelines § Product structure § The development environment is based on the implementation view. § Team structure § is based on the structure of the implementation view. 17
