|Column name|Data type|Description|  
|-----------------|---------------|-----------------|  
|name|**sysname**|Name of data space, unique within the database.|  
|data_space_id|**int**|Data space ID number, unique within the database.|  
|type|**char(2)**|Data space type:<br /><br /> FG = Filegroup<br /><br /> FD = FILESTREAM data filegroup<br /><br /> FX = Memory-optimized tables filegroup<br /><br /> **Applies to**: [!INCLUDE[ssSQL14](../../includes/sssql14-md.md)] and later.<br /><br /> PS = Partition scheme|  
|type_desc|**nvarchar(60)**|Description of data space type:<br /><br /> FILESTREAM_DATA_FILEGROUP<br /><br /> MEMORY_OPTIMIZED_DATA_FILEGROUP<br /><br /> **Applies to**: [!INCLUDE[ssSQL14](../../includes/sssql14-md.md)] and later.<br /><br /> PARTITION_SCHEME<br /><br /> ROWS_FILEGROUP|  
|is_default|**bit**|1 = This is the default data space. The default data space is used when a filegroup or partition scheme is not specified in a CREATE TABLE or CREATE INDEX statement.<br /><br /> 0 = This is not the default data space.|  
|is_system|**bit**|**Applies to**: [!INCLUDE[ssSQL11](../../includes/sssql11-md.md)] and later.<br /><br /> 1 = Data space is used for full-text index fragments.<br /><br /> 0 = Data space is not used for full-text index fragments.|
