We have 3 types of file extensions in SQL Server. MDF, NDF and LDF each one representing Primary, Secondary and Log file respectively. Do you think these extensions are need to be given to the respective files? If your answer is yes then you are wrong. You can give any extension as you like or else you can even interchange these 3 extensions to primary, secondary and log file. Extension plays a important role for us to understand which file is what where as when you attach the db, SQL (by pointing the primary file) knows where the log file and the additional files for the db, it will attach the database without any errors. This is because SQL will check the primary file (which you have pointed) and if it’s in right format then it will start reading the header page to fetch additional details about other files and attach the database.

Performance Data Collector is one of the new features that’s accompanied from SQL Server 2008. If you are a DBA , you know it’s very hard to get performance data from necessary inputs. We will get the data from Perfmon (system monitor), profiler, DMV etc and correlating this data is very hard, implementing the same process or scripts across your environment is also time consuming one. To Overcome this MS has added Performance data collector feature in SQL 2008. In a Nutshell performance data collector will collect performance data (integrating all your data from your server), upload it in centralized management data warehouse (MDW) in relational format and finally allows you to see reports in graphical format.
