Getting Started with Windows Azure Data Storage

Windows Azure Data Storage

Account Name / Key
AccountName
A unique name identifying the Azure Data Storage
AccountKey
A blob of encrypted data used for authentication

Windows Azure Data Storage - Blobs
Unstructured data storage
Partitioned by container
Unlimited containers

Windows Azure Data Storage - Tables
Windows Azure Table provides scalable, available, and durable structured (or semi-structured) storage in the form of tables.
The tables contain entities, and the entities contain properties.
The tables are scalable to billions of entities and terabytes of data, and may be partitioned across thousands of servers.
The tables support ACID transactions over single entities and rich queries over the entire table.
Simple and familiar .NET and REST programming interfaces are provided via ADO.NET Data Services.

Windows Azure Data Storage – Tables (Terms Part 1)
Table – contains a set of entities.
Entity (Row) – Entities are the basic data items stored in a table.
Property (Column) – This represents a single value in an entity.
PartitionKey– The first key property of every table. The system uses this key to automatically distribute the table’s entities over many storage nodes.

Windows Azure Data Storage – Tables (Terms Part 2)
RowKey– A second key property for the table. This is the unique ID of the entity within the partition it belongs to.
Timestamp – Every entity has a version maintained by the system.
Partition – A set of entities in a table with the same partition key value.
Sort Order – There is a single index provided for the CTP, where all entities in a table are sorted by PartitionKey and then RowKey
