Although other characteristics of these items exist, such as behavior, fitness-for-purpose, and even aesthetics, it is the structural characteristic that is the most familiar and the most-often mentioned.It should not surprise you then that if you ask someone to describe the architecture of a software system he's working on, you'll probably be shown a diagram that shows the structural aspects of the system -- whether these aspects are architectural layers, components, or distribution nodes. Similarly, different stakeholders may express conflicting needs and, again, an appropriate balance must be achieved. Like a pattern, an architectural style represents a codification of experience, and it is good practice for architects to look for opportunities to reuse such experience. In order to execute, the software runs on some kind of hardware. Thus, an important consideration is to ensure that you document the decisions that have led to this architecture and the rationale for those decisions.This information is relevant to many stakeholders, especially those who must maintain the system. This is sometimes referred to as "architecture in context." This content is no longer being updated or maintained. What is the difference between an enterprise architecture and a system architecture? As a result, the content has been commented upon by many individuals that I would like to thank, who are Grady Booch, Dave Braines, Alan Brown, Mark Dickson, Holger Heuss, Kelli Houston, Luan Doan-Minh, Philippe Kruchten, Nick Rozanski, Dave Williams, and Eoin Woods. A component may be logical or physical, technology-independent or technology-specific, large-grained or small-grained. However, most definitions of architecture do not define the term "component," and IEEE 1471 is no exception, as it leaves it deliberately vague to cover the many interpretations in the industry. The environmental factors that influence the architecture include the business mission that the architecture will support, the system stakeholders, internal technical constraints (such as the requirement to conform to organizational standards), and external technical constraints (such as the need to interface to an external system or to conform to external regulatory standards).Conversely, as eloquently described in Bass, Clements, and Kazman,When it comes to software-intensive systems, there is a particular aspect of the environment that must always be considered, as discussed earlier in this chapter. Even in the field of software engineering, we often come across different forms of architecture. Software cannot achieve these properties in isolation of the hardware on which it executes.IEEE Std 12207-1995, the IEEE Standard for Information Technology -- Software Life Cycle Processes, defines a system differently from the IEEE 1471 system definition noted earlier (which focuses on software-intensive systems), but is in agreement with the definitions found in the systems engineering field: A configuration of the Rational Unified Process® for Systems Engineering (RUP SE) contains a similar definition. It is these interactions that provide the desired system behavior. Either the scope can be reduced in order to meet the schedule or all of the functionality can be provided within an extended timeframe. static.content.url=http://www.ibm.com/developerworks/js/artrating/ More complex scenarios require certain system qualities to be achieved through a combination of software, hardware, and people. This is a pitfall that is best avoided, since the result is typically a less-than-ideal architecture. It therefore makes perfect sense to align software development team structures with the architecture once it has been defined. For example, if performance is key, then a decision may be made to implement certain system elements in hardware, rather than software or people. Nonfunctional requirements are quite often the most significant requirements as far as an architect is concerned.An important aspect of an architecture is not just the end result, the architecture itself, but the rationale for why it is the way it is.
