In the example, this is the module Stdio. In this view, the relation between modules is uses, as described in Chapter 2. If the view is to be used to reason about viewrype schedulability, component types will likely be schedulable entities.
Overview | The Component-and-Connector Viewtype
The client-server connector allows a set of concurrent clients to retrieve data synchronously via service requests. Uses of Architecture Documentation P. Uses of Architecture Documentation P. Software Architectures and Documentation P. A set of client tellers cobnector interact with the account repository servers, embodying a client-server style.
This system contains a shared repository that is accessed by servers and an administrative component. Two of the three connector types in Figure 3.
Styles of the Component-and-Connector Viewtype
This variant of the client-server style supports transparent failover to a backup server. The Process of Software Architecting. Each of these connectors represents a complex form componeng interaction and will likely require nontrivial implementation mechanisms.
The database access connector supports authenticated administrative access for monitoring and maintaining the database. The Definitive Guide Definitive Guides. Seven Rules for Sound Documentation P. Although not illustrated in this example, the same code module might be mapped to several execution components: Viewwtype Architecture in Practice 2nd Edition.
Some of these problems follow from the usual pitfalls of visual documentation and are equally applicable to any of the viewtypes discussed donnector this book. In particular, there is a natural relationship between the componentsSplit, To-upper, To-lower, and Mergeand the modules that carry out the bulk of the computation.
Pathways of communication between the components are explicit, indicating that during runtime, the pipe connectors will mediate communication of data streams among those components. For example, a component may be a server in a client-server system. A main module is used to start things off, invoking the facilities of four modulesTo-upper, To-lower, Split, and Mergethat do the main work.
Finally, even in these types of cases, some correspondences are worth noting. Certified Ethical Hacker Exam Prep. Software Architecture in Practice 2nd Edition. Such a view may contain many instances of the same component type.
Relation to Other Viewtypes
Note also that connectors need not be binary: 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. For Further Reading Part I.
We learn from the supporting documentation that the purpose of the two servers is to enhance reliability: The Process of Software Architecting.
The Role conector Architecture P. Click here to find out more. We discuss sixpipe-and-filter, shared-data, publish-subscribe, client-server, peer-to-peer, and communicating-processesthat apply to a wide variety of systems and provide enough semantic richness to illustrate documentation principles.
Just Enough Software Architecture: Other interactions might represent multiparty forms of communication, such as event broadcast, or n-way data synchronization. Finally, a component allows an administrator to access, and presumably maintain, the shared-data store.
For example, you might have a Web client component type that is instantiated many times within the same view. If you may any questions please contact us: The same component may also act as a respository for data. A bird’s-eyeview of connectir system as it might appear during runtime. 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 interactions may represent complex forms of communication.
Relation to Other Viewtypes | The Component-and-Connector Viewtype
The publish-subscribe connector supports asynchronous event announcement and notification. If you may any questions please contact us: Often, these interactions are carried out using complex infrastructure, such as middleware frameworks, distributed communication channels, and process schedulers.
