SSDS MIX08 Session Summary

Saturday, March 8th, 2008

Watched Nigel Eillis’ MIX08 presentation today: http://sessions.visitmix.com/?selectedSearch=BT05.  Here is a short summary on what I have learned about SSDS.

• SSDS is a layer of WS been put on top of MSFT’s 18k+ SQL servers.
• Taking Invitation only Beta application now, public Beta within 6 month, go live in Q1, 09.
• SSDS supports REST and SOAP services now, will support more later.
• There are three concepts you need to know:
  • Authority
  • Container
  • Entity
• Authority contains Containers, and Container contains Entities.
• No schema is needed for Containers and Entities.
• Entities have two kinds of properties:
  • Fixed properties.  There are three so far:  ID, Kind, Version.  They are referenced as SomeEntity.ID, SomeEntity.Kind, SomeEntity.Version.
  • Flex properties.  Can be any number if them.  Referenced as SomeEntity["SomeProperty"].  Same property name on different entities needs not to be the same type.  E.g. “DatePublished” on EntityA can be a datetime, but on EntityB could be a string.
•  Queries are in LINQ like syntax.
