Intelligent SQL Server REORGANIZE and REBUILD Script

I've been doing a lot of database analysis recently, and fortunately I'm one of those people that enjoys it. I'm primarily a .Net developer, but I've spent many years looking after SQL Server databases, helping out (and even educating) DBAs, writing ETL packages and designing both large and complex databases. The database in question was in pretty bad shape; missing, unnecessary, and extremely fragmented indexes, missing primary and foreign keys, bad normalisation, and (the main reason I decided to look into it) undesired table locks during ETL operations. It's a 24/7 system, and live lookups are performed around the clock - data is imported early in the morning (when usage is at a minimum), which is when most of errors occur. Amongst many other pre-emptive actions I've recently performed on the database, I decided to set up regular table index maintenance job to keep queries as quick as possible.

Handling uploads with MVC4, JQuery, Plupload and CKEditor

The upload form is created using a combination of Editor Templates, JQuery and AJAX. I will be stripping down any examples to their bare bones to make things a little clearer. This article assumes you are familiar with MVC fundamentals such as creating controllers, views and models within Visual Studio 2010 or later, you
