SQL Server 2014: ONLINE operation on a single partition of partitioned object

Here I continue a series of articles devoted to new options in SQL Server 2014. Today let's review another useful operation - ONLINE rebuilding some partitions of partitioned objects (tables or indexes).First let me remind you that some versions of SQL Server (Enterprise, Evaluation, Developer) allow you to perform a number of operations in ONLINE mode. The main advantage of this mode is that we can create / change index and keep on working with the data (including changing these data) at the same time.This happens due to the fact that schema lock (Sch-M) is not retained throughout creation / changing process.

Top 4 Reasons to decide on Remote DBA Services

Before we review what remote DBA services are, let’s clarify the DBA itself. Database administration or shortly DBA aims to maintain functionality, safety and integrity of database management software – Oracle, DB2 and SQL Server in the first hand. Nobody wants to end up with a non-working system with all the data become unavailable or even lost. So the scope of DBA services covers every matter that explicitly or implicitly influences the operation of a DBMS.
