Software Architecture in Practice 2nd Edition. In the example, we have Main and Config. For example, you might have a Web client component type that is instantiated many times within the same view. Software Architecture in Practice 2nd Edition. For example, does the use of the administrative interface lock connextor the servers?
The Process of Software Architecting.
Relation to Other Viewtypes | The Component-and-Connector Viewtype
Just Enough Software Architecture: Two of the three connector types in Figure 3. Note also that connectors need not be binary: The component-and-connector viewtype is specialized by numerous styles. It should be clear even with this simple example that the two descriptions differ wildly in what they include and how they partition the system. In this view, the relation between modules is uses, as described in Chapter 2. For instance, the design decision that causes the administrative interface to be the only way to change the database schema would have a positive impact on the security of the system.
Thus, assuming that both client-server and shared-data styles are important to understanding the system, views in both styles will include the same component, showing different patterns of interaction. For Further Reading Part I. These client components communicate among themselves by publishing and subscribing to events. Conversely, the pipe connector does not appear in the module view, although one might argue that it is most closely associated with the module Stdio.
Styles of the Component-and-Connector Viewtype
Each of the components is a filter that transforms character streams. Click here to find out more. Some of these problems follow from the usual pitfalls of visual documentation and are equally applicable to any of the viewtypes discussed in this book.
These interactions may represent complex forms of communication. The Role of Architecture P. The documentation accompanying the figure elaborates on the elements shown.
Other interactions might represent multiparty forms of communication, such as event broadcast, or n-way data synchronization.
The simple system illustrated here accepts a stream of characters as input and produces a new stream of characters identical to the original but with uppercase and lowercase characters alternating. We are being shown a bird’s-eyeview of the system as it might appear during runtime.
A set of client tellers can interact with the cknnector repository servers, embodying a client-server style. The database access connector supports authenticated administrative access for monitoring and maintaining the database. Often, these interactions are carried out using complex infrastructure, such as middleware frameworks, distributed communication channels, and viwwtype schedulers.
Also, the mapping of interfaces comnector not at all obvious. These modules can be more easily seen by factoring out modules that are associated with setup and modules that implement communication infrastructure.
Just Enough Software Architecture: Identifying and Managing Project Risk: For example, a connection between a client component and a server component might represent a complex protocol of communication, supported by sophisticated runtime infrastructure. Additionally, component-and-connector models include as elements the pathways of interaction, such as communication links and protocols, information flows, and access to shared storage.
c) Component-and-Connector (C&C) Views – Software Architecture in Practice
Software Architectures and Documentation P. The publish-subscribe connector supports asynchronous event announcement and notification.
Viewtypes and Styles P. Certified Ethical Hacker Exam Prep. If the view is to be used to reason about vieetype schedulability, component types will likely be schedulable entities.
The Process of Software Architecting. A bird’s-eyeview of a system as it might appear during runtime. This variant of the client-server style supports transparent failover to a backup server. Seven Rules for Sound Documentation P.
Similarly, by knowing properties about the reliability of the individual servers, you might be able to produce numeric estimates of the overall reliability of the system, using some form of reliability analysis. The Definitive Guide Definitive Guides. The Process of Software Architecting.
