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
