Forwarded records in SQL Server can cause performance issues on heap tables because the record outgrows the page and the database engine uses pointers to reference the data. The best practice is to have a clustered index on every table, however, sometimes there are cases when a clustered index is not needed.
How you examine and approach a problem might have a large impact on how you solve it. Steve Jones notes that it's important that all of us look at the problem from the point of view of the customer, as well as our own view.
The continuing drop in the price of memory has made fast in-memory OLTP increasingly viable. SQL Server 2014 allows you to migrate the most-used tables in an existing database to memory-optimized 'Hekaton' technology, but how you balance between disk tables and in-memory tables for optimum performance requires judgement and experiment.
This metric returns the number of check constraints that have their is_not_trusted flag set to 1 in the sys.check_constraints table. Untrusted constraints force SQL Server to construct less efficient query plans, because it doesn’t know enough about the kind of data contained in the table. This can point to a data integrity issue which should be investigated.
Is there a better way to put together a conference or event? Today Steve Jones speculates on how events are run and how we might change things.

SQL Server 2012 Integration Services introduces an innovative approach to deploying SSIS projects, known as Project Deployment Model. However, the traditional, package-based methodology remains available and supported, and, in some scenarios, it might be considered more viable, since it allows for separation of SQL Server Database Engine and SQL Server Integration Services.
