Explains how to access schema-free NoSQL data storages like Microsoft Azure Table Service without the need for ORM/ODMs.

1. SCHEMA-FREE AZURE
DEVELOPMENT
By Example.

2. AZURE SCHEMA-FREE DATABASES
 Windows Azure Storage:
 Table storage NoSQL database.
 Massively scalable and Big Data capable (500 TB/Storage account).
 REST API (OData).
 Strongly typed .NET storage client object model.
 http://azure.microsoft.com/en-us/documentation/services/storage/
 NuGet: Install-Package WindowsAzure.Storage -Version 4.3.0

3. AZURE SCHEMA-FREE DATABASES
 Windows DocumentDB(released April ‘15):
 JSON document NoSQL database.
 1 TB/database.
 REST API.
 Strongly typed .NET storage client object model.
 «SQL-like» declerative query syntax.
 Supports dynamically typed declerative queries.

4. SCHEMA-FREE ADVANTAGES
 Boost developer performance:
 No need for database schema defintions.
 No need for Object-relational mappings (ORMs).
 No need for manual entity definitions in code.

5. THE OPTIMAL SOLUTION
 Create tables on the fly.
 Create table rows on the fly.
 Create entity properties on the fly.
 Support all data types.
…Solved using Dynamic Typing.

6. IMPLEMENTING DYNAMIC TYPING
 Inherit DynStorage from
System.Dynamic.DynamicObject.
 Implement TryGetMember().
 Create a table object by table name.

7. IMPLEMENTING DYNAMIC TYPING
 Inherit DynTable from
System.Dynamic.DynamicObject.
 Implement TryGetMember().
 Create an entity object by partition key
(primary key) and rowkey.
C# code available from http://ingehenriksen.wordpress.com

8. IMPLEMENTING DYNAMIC TYPING
 Inherit DynTableEntity from System.Dynamic.DynamicObject, ITableEntity, and
Idictionary<string, EntityProperty>.
 Implement TryGetMember().
 Fetch entity property from dictionary.
 Implement Save() method.
C# code available from http://ingehenriksen.wordpress.com

9. IMPLEMENTING DYNAMIC TYPING
 Implement dictionary EntityProperty().
 Write TableQuery() using partitionkey and
rowkey.
 Implement TryGetMember().
 Create an entity object by partition key
(primary key) and rowkey.
