You are developing a Windows Store app for purchasing school supplies.
The app has the following storage requirements:
Inventory data must be accessible to the app and over the Internet to external suppliers.
Suppliers will access the data over HTTP by using OData.
App storage for the high volume sales periods must be able to scale rapidly, but at the
lowest possible cost.
Color preferences for the user must be stored on the host device.
You need to choose the appropriate data access strategy for each requirement.
Which data access strategies should you use? (To answer, drag the appropriate data access
strategies to the correct requirements in the answer are

Explanation:
Box 1:
The Windows Azure storage services provide storage for binary and text data, messages,
and structured data in Windows Azure. The storage services include:
The Blob service, for storing binary and text data
The Queue service, for storing messages that may be accessed by a client
The Table service, for structured storage for non-relational data
Windows Azure drives, for mounting an NTFS volume accessible to code running in your
Windows Azure service
Box 2: With HTML5, web pages can store data locally within the user’s browser.
Earlier, this was done with cookies. However, Web Storage is more secure and faster. The
data is not included with every server request, but used ONLY when asked for. It is also
possible to store large amounts of data, without affecting the website’s performance.
The data is stored in key/value pairs, and a web page can only access data stored by itself.
