Hi,
Why SQL Database files ware called "Virtual File". Like sys.dm_io_virtual_file_stats - defination of this DMV is "Returns I/O statistics for data and log files. This dynamic management view replaces thefn_virtualfilestats function."
This DMV returns I/O Statistics for data and log files. Then why we cannot call this DMV as dm_io_physical_file_stats or dm_io_database_file_stats? why sql team suggest name "virtual_file"?
