This page contains the draft version of the HSPC functional architecture specification, and serves as a hub for the various task forces working on different aspects of the HSPC architecture.
HSPC Architecture Proposals
The HSPC functional specification is based on a layered, "pyramidal" architecture.
- The Infrastructure layer contains the foundation services. These are commodity capabilities available from most infrastructure providers. The Core Infrastructure are base services that all systems and architectures would use, and are not necessarily specific to the support of Service Oriented Architectures
- The SOA Infrastructure layer incorporates SOA-oriented services that...
- The Enabling, or Horizontal Services layer contains services that are business oriented, but not inherently domain specific. These are the base "building blocks" to be used by more complicated, higher level services.
- The Coordinating, or Vertical Services layer contains healthcare domain specific services. These services are business oriented services. and generally utilize, by composition or orchestration, the Enabling Services, leveraging domain-specific content as guidance.
Core Platform Infrastructure
SOA Architectures require an underlying infrastructure, that is tailored to, but not specific to healthcare-related services.
Most cloud platforms offer capabilities such as:
- Storage
Storage solutions should not be limited to relational DBs, but include a combination of graph, document, XML, object, key-value, column and other "NOSQL" databases, to afford for optimal solutions based on applications' needs. - Computing
- Network
- Analytics
Analytics - as in the materialization of the HSPC knowledge architecture within the HSPC service architecture is a broader notion that spans across the stack.
This is in contrast with a more focused notion of analytics as in the application of data mining and visualization techniques to large data sets (e.g. using SAS, R or Tableau) - Internet of Things (IoT)
Particular emphasis should be given to device and device data integration across the stack.
HSPC defines the principles and requirements for the HSPC Core Platform Environment in a dedicated space.
SOA Infrastructure
This is general purpose SOA Infrastructure, not specific to healthcare.
