software architecture technology guiding principles
Software Architecture & Technology “Guiding principles”
  • Provide a consistent and logical user view of data and state based on latest data, pending work, and potential conflicts.
  • Move from user initiated synch to a connectivity availability synch model
  • Provide a common interface to all user devices, scale functionality
  • Allow the user to modify app and system policies relating to consistency, synchronization, power mgmt, conflict resolution, etc.

User Experience

  • Make mobility an integral aspect of the application design
  • Assume & embrace asynchronous interactions & intermittent connectivity (Adopt a Service Oriented Architecture at the business layer; client and server)
  • Use data synchronization models for small, easily partitioned data sets and a business synchronization logic for complex data sets
  • Separate application logic from synchronization logic (Online/Offline transparency handled by a OCC proxy)
  • Architect for optimal use of resources (e.g. Power Management)
  • Address multi-master and multi-device synchronization

ApplicationArchitecture

  • Make the application network protocol independent (TCP/IP or Other)
  • Use open industry standard transport protocols (HTTP, HTTPS, FTPS, etc)
  • Use XML (at least), SOAP/WSDL (better) to exchange data & state/events
  • Use standard security mechanisms (SSL, client/server X.509 certificates, VPN, etc)
  • Use platform OS event policies & QoS capabilities for connectivity
  • Recognize & utilize device characteristics and capabilities
