To access Azure storage you must use a valid account. When a new Azure storage account is created using the Windows Azure portal web interface, a 256-bit public shared key will be sent to you via e-mail. Usually it takes about couple of days for processing. The secret key must be passed as one of the parameters when initializing storage table access. The access will be authenticated based on the secret key. Authentication is required for each request to table storage. When REST is used to access table storage, the account name is part of the host name in the URL string. The URL is constructed with the format of http://<accountName>.table.core.windows.net. An example of an account can be found from DevelopmentStorage.exe.config of the Windows Azure SDK. The following are the key parts of the specification: Table: A table contains a set of entities. Table names are associated to the account. There is no limit on how many tables an application may create within a storage account. Entity: An entity can be understood as a row in cloud table storage, which is the basic data item stored in a table. An entity has a set of properties. Property: A property can be understood as a value being held in an entity. The name for a property is case-sensitive. A rich type set is supported for property values, as Table 1-1 shows.

PartitionKey: Every table has a special property called PartitionKey. Since the actual data of table storage is physically distributed to many storage nodes, which may cross many storage servers running in the cloud, the cloud storage system uses this key to manage the storage nodes distribution. RowKey: RowKey is the second key property defined for each table storage. This is the unique ID of the entity, and an entity can be identified using the combination of the PartitionKey and RowKey in a table. Timestamp: The Timestamp indicates the time a table is created. Partition: The Partition is a logical set of entities defined in a table with the same PartitionKey value. Sort Order: A single index is provided for all entities in a table. Data entities are sorted by PartitionKey and then RowKey. This makes queries specifying these keys more efficient.

It s worth having a closer look at entities before we go any further: Number of properties: The maximum number of properties an entity can define is 255, including PartitionKey, RowKey, and Timestamp. Type: PartitionKey and RowKey are of string type. Timestamp: Timestamp is a read-only property.
CHAPTER 1 CREATE CLOUD TABLE STORAGE
Schema: There is no schema stored in Windows Azure tables. The data storage model for properties is a name and typed value pair. A table can not have two entities with the same name, but it may have two properties with the same name because they belong to different parent entities. Size of an entity: The size limit for an entity is 1 MB. This size is the summation of the size of the property, the property values or their types, and the two mandatory key properties, PartitionKey and RowKey.
Now that we know a little about Azure s table storage, we should look at development storage, which allows us to test our Azure applications on our local machine.
Azure Development Storage
The Windows Azure SDK development environment includes out-of-the-box development storage, a utility that simulates the storage services available in the cloud. The Azure SDK provides the development storage services to allow developers to create, debug, and unit test the cloud data service on a local machine before they deploy their application to production. By default, development storage relies on a SQL Server Express database, either the 2005 edition or the 2008 edition, to simulate the storage environment in the cloud. It s possible to use the full SQL Server as we ll see next, but to use SQL Server Express, you must have it installed. You also need to install SQL Server Management Studio to manage SQL Server Express. Development storage connects to SQL Server Express by using Windows authentication. To switch from SQL Server Express to SQL Server 2005 or 2008, you need to modify the configuration file, DevelopmentStorage.exe.config, and one line in the DevtableGen.exe.config file, as shown in Listing 1-1 and Listing 1-2. These configuration files are located in the bin directory of Windows Azure as shown in Figure 1-1.
