Software Architectural Styles

1. Software Architectural Styles Description:

Sr. #	Style Name	Component Types	Connectors	Configuration / Topology	Quality Attributes
1.	Process Control Architecture	Processes	Message Protocol	Arbitrary	· Performance · Reusability
2.	Message Bus Architecture	· Schemas · Shared Data Infrastructure	Buses	Network	· Extensibility · Scalability · Flexibility · Performance
3.	Component based Architecture	· Software package · Service · Resource containing related functions	Interface	Components are put together on a single platform thus creating a new system	· Maintainability · Performance · Reusability · Reliability
4.	Service Oriented Architecture (SOA)	Services	Communication protocol over network	Varying topology based upon business structure	· Reusability · Maintainability · Interoperability
5.	Mobile- Code Architecture	· Execution Dock – Code and State handler · Code compiler / interpreter	· Network protocols · Elements for code packaging · Transmission data	Network	· Performance · Adaptability
6.	Acyclic	Transducers	Data Stream	Acyclic	· Modifiability · Simplicity · Robustness
7.	Fanout	Transducers	Data Stream	Hierarchy	· Modifiability · Simplicity · Robustness · Reusability
8.	Dataflow Network	Transducers	Data Stream	Arbitrary	· Modifiability · Simplicity · Robustness
9.	Closed Loop Control	· Embedded process · Functions	Continuous Refresh	Fixed	· Modifiability · Simplicity · Robustness
10.	Information Hiding	Managers	Procedure Calls	Arbitrary	· Decomposition · Abstraction · Accuracy · Encapsulation
11.	Lightweight Processes	· Lightweight Processes · Data Structures	· Threads · Shared Data	Arbitrary	· Performance · Scalability
12.	Abstract Data Types	Managers	Static Procedure Calls	Arbitrary	· Modifiability · Performance
13.	Distributed Objects	Managers	Remote Procedure Calls	Arbitrary	· Performance · Scalability
14.	Process – based Naive Client/Server	Processes	Reply/Request Messages	Star	· Performance · Scalability
15.	Token Passing	Processes	Message Protocols	Arbitrary	· Performance · Scalability
16.	Probe/Echo	Processes	Message Protocols	Incomplete Graph	Scalability
17.	Replicated Worker	Processes	Message Protocol	Hierarchy	· Performance · Scalability
18.	Transactional Database	Memory Computations	Transaction Streams (queues)	Star	· Performance · Scalability
