For an html/Css/JQuery public Azure website to be coded using Zurb Foundation html5 responsive framework, I'd like to use SQL Azure (web edition) to store product descriptions and links to images that I store in Azure Blob Storage.
Therefore I would want to link my SQL Azure to my Zurb Foundation Azure Website and have an easy interface (I'm an absolute beginner in dba) to insert and update product descriptions. I'd like to be able to import the product descriptions, links and whatever other useful info for SEO from csv files.
Will a relational db like SQL azure perform well for this application (even if it scales to a few hundred to say three thousand concurrent users) or should I select from a document database or key/value database application (mongoDB, CouchDB etc?) that I would host in Azure ?
