[Notes from Pinal]: In my career, I have seen many database experts who are great with what they do, but when they have to work with clustering or AlwaysOn solutions, they usually avoid it. The reason is that there are not many experts who know this subject well enough. One thing I always personally felt that the documentation is also not widely available when it is about clustering. If one receives some error, they are usually lost. This is when I reached out to Eduardo and asked him what can we do to if we face error while attaching or restoring database in clustering environment in SQL Server.

As an independent database consultant, I often face a challenge when analyzing the performance of SQL Server instances, which I see for the first time in my life. In many cases, this may seem a difficult task, because in order to fix something you must first understand the database structure. A great many of the companies do not document their database. And even if documentation exists, it is rarely updated. As a result, we have the following situation – documentation is either obsolete, or does not reflect the actual state of things. Let understand SQL SERVER – View Dependencies.
