Tinnitus is the name for these head noises, and they are very common. Nearly 36 million other Americans suffer from this discomfort. Tinnitus may come and go, or you may be aware of a continuous sound. It can vary in pitch from a low roar to a high squeal or whine and you may hear it in one or both ears.
By default, the directory where all database files and transaction log files are located is \Program Files\Microsoft SQL Server\Mssql.1\Mssql\Data. When you run SQL Server Setup, you can specify a different location as the default location for data files. The data file location is the root directory where Setup creates the folders that contain database and log files, in addition to directories for the System log, back-up, and replication data.
SQL Server supports table and index partitioning. The data of partitioned tables and indexes is divided into units that can be spread across more than one filegroup in a database. The data is partitioned horizontally, so that groups of rows are mapped into individual partitions. All partitions of a single index or table must reside in the same database. The table or index is treated as a single logical entity when queries or updates are performed on the data. Prior to SQL Server 2016 SP1, partitioned tables and indexes were not available in every edition of SQL Server.
