Describe how filegroups are used in a database.
What will be an ideal response?
Data files are placed into filegroups for storage management. Each database must have a primary filegroup with at least one data file. However, a database may have more than one data file in a filegroup; the database is able to use all the data files concurrently, which can improve performance. If using more than one data file within a filegroup, the data files should all be the same size as the database attempts to fill them equally.
