Azure Tables

Tables - Capabilities What tables don’t do Not relational No Referential Integrity No Joins Limited Queries No Group by No Aggregations Limited Indexes No Transactions What tables can do CheapCheap Very Scalable FlexibleFlexible DurableDurable If these are important to you, use:

Data Model Data stored in Tables A Table is a set of Entities (rows) An Entity is a set of Properties (columns) Entity has: PartitionKey – enables scalability RowKey – unique id within the partition the only indexed property Timestamp – for optimistic concurrency 255 properties for your data Max size of 1MB
