pipes Separates communication from computation May influence non-functional system characteristics e.g. procedure call, RPC, shared data access, message passing Constraints on communication structure/direction e.g. Supports data transmission: Different communication mechanisms e.g.

calls or shared data accesses, but much more sophisticated connectors are used in practice Connectors typically provide application-independent interaction facilities 6 3Ĥ Configurations Components and connectors are composed in a specific way in a given system s architecture to accomplish that system s objective Notional definition: An architectural configuration, or topology, is a set of specific associations between the components and connectors of a software system s architecture 7 More on Software Connectors Connectors often overlooked in architecture discussions Connectors manage more than just control flow Data movement Checking interaction protocol Services: persistence, transactions, load balancing, etc. entity that Encapsulates system functionality and/or data Restricts access via explicitly defined interfaces Has explicitly defined dependencies on its required execution context Components typically provide application-specific services 5 Connectors Notional definition: A software connector is an architectural building block that manages component interactions Connectors often simple proc. s have 3 types of elems Components Connectors Configuration 4 2ģ Components Elements that encapsulate processing and data in a system s architecture Definition: A software comp. for talking about system structure 2 1Ģ The Architecture of Software Notional definition: A software system s architecture is the set of principal design decisions about the system Software architecture is the blueprint for a software system s construction and evolution Design decisions encompass every facet of the system under development Structure Functional behavior Interaction Non-functional properties Implementation 3 Software Architecture Elements One view: s/w arch.
