  30. Backup

  31. 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 SW Platform Features
