Service Layer Pattern¶
Service layer is an architectural pattern, applied within the service-orientation design paradigm, which aims to organize the services, within a service inventory, into a set of logical layers.
Core Idea¶
Service Layer Pattern is treated here as the recurring computer science and information systems identity summarized by this source-grounded definition: Service layer is an architectural pattern, applied within the service-orientation design paradigm, which aims to organize the services, within a service inventory, into a set of logical layers. Service layer is an architectural pattern, applied within the service-orientation design paradigm, which aims to organize the services, within a service inventory, into a set of logical layers. Services that are categorized into a particular layer share functionality.
Scope of Application¶
-
Rationale. Restricting each layer to a particular functionality, simplifies the design of the service.
-
Usage. Applying this pattern requires creating a service inventory blueprint, a list of services with associated functionality.
-
Usage. Adopting a common layering strategy across the enterprise facilitates reuse in other applications, because developers don't have as much to learn (or invent) when they join a project.
-
Rationale. Grouping services into functional layers reduces the impact of change.
-
Usage. Next, group the services into layers according to function.
Clarity¶
A clear use of Service Layer Pattern names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is Service layer is an architectural pattern, applied within the service-orientation design paradigm, which aims to organize the services, within a service inventory, into a set of logical layers.
Manages Complexity¶
Service Layer Pattern compresses multiple computer science and information systems details into a stable diagnostic relation. The source shows both the central mechanism—applying this pattern requires creating a service inventory blueprint, a list of services with associated functionality.—and the practical consequence—similarly, the service composability principle advocates designing services so that they can be composed in various ways.
Abstract Reasoning¶
- Type the carrier. Identify the computer science and information systems entities to which the claim applies.
- State the relation. Use the source-grounded identity: Service layer is an architectural pattern, applied within the service-orientation design paradigm, which aims to organize the services, within a service inventory, into a set of logical layers.
- Check operation and conditions. An alternative layering from Bieberstein et al., involves five layers, namely enterprise, process, service, component and object.
- Demand recognition evidence.
Knowledge Transfer¶
Within the home domain. Knowledge about Service Layer Pattern transfers literally when a new case preserves the same carrier type, relation, and recognition test. Restricting each layer to a particular functionality, simplifies the design of the service. Applying this pattern requires creating a service inventory blueprint, a list of services with associated functionality. Beyond the home domain. Transfer the broader Pattern relation when the computer science and information systems-specific differentia cannot be filled. Retain the name Service Layer Pattern only when the same carrier, operation, and rejection conditions are present literally rather than metaphorically.
