    <p>I recommend taking a look at CQRS, which stands for Command Query Responsibility Segregation.</p> <p>The purpose of this architecture is to create systems that are loosely coupled, extensible, and scalable.</p> <p><a href="http://cqrsjourney.github.com/" rel="nofollow">http://cqrsjourney.github.com/</a></p> <p>Greg Young invented this system and there are a number of open source implementations available to expedite the building of distributed, scalable systems. Before him was Bertrand Meyer, who laid the groundwork.</p> <p>The oversimplified concept is that a series of queues separate web roles and worker roles. So when users submit work from a web role, that work gets queued up, and later picked up by a worker role. A trade off is that there is eventual data consistency, not immediate consistency. The benefit is that it is loosely coupled and scalable. If the queue starts to grow too big, additional worker roles can be added to handle the additional scale.</p> <p>The approach uses concepts like Commands, Queries, Domain objects. CQRS is becoming an extremely powerful way to accomplish the goals I think you are seeking.</p> <p>A search engine can give you many good resources. Here are some useful videos: Greg Young <a href="http://www.youtube.com/watch?v=KXqrBySgX-s" rel="nofollow">http://www.youtube.com/watch?v=KXqrBySgX-s</a> My Friend Rinat <a href="http://www.youtube.com/watch?v=CnvO_nlvrps" rel="nofollow">http://www.youtube.com/watch?v=CnvO_nlvrps</a></p> <p>Good luck!</p>

    1. COLooks to me that this is another redundant product from Microsoft. Went over their homepage, bunch of text about nothing. I am wondering what is the difference between Azure Storage Queues and this CQRS... I find this to be a big issue with MS that they keep spitting out redundant products, that no one knows what they are for. There are too many people working there and they have to keep themselves occupied and the result is all these products that no one ever uses.

    2. COCQRS has got nothing to do with a MSFT product, it an industry standard pattern on which MSFT are providing guidance on, on how to use it in Windows Azure. Take a look at Martin Fowler blog post on it if you want to know more. http://martinfowler.com/bliki/CQRS.html I suggest you open up a new thread on the difference between Azure Storage Queues and CQRS...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
