Please, add LINQ2DynamoDB to data access section

LINQ2DynamoDb is a type-safe data context for AWS DynamoDB with LINQ and in-memory caching support. 

Allows to combine DynamoDB's durability with cache speed and read consistency. Translates LINQ queries into corresponding DynamoDB Get/Query/Scan operations and stores query results in an in-memory cache. Data updates are propagated both to DynamoDB and cache.

Bridges the gap between AWS SDK's object model and Microsoft's stack of data access technologies like data binding, ASP.Net datasources etc. Also allows to easily expose data from DynamoDB as an OData endpoint.
