尊敬的腾讯云用户，您好：
腾讯云数据库 SQL Server 计划于2023年02月07日起，调整磁盘存储空间的组成规则，新增实例系统库纳入磁盘存储空间的统计。
调整前磁盘存储空间由数据文件空间、事务日志文件空间、临时表文件组成。
调整后磁盘存储空间由数据文件空间、事务日志文件空间、临时表文件、系统库组成。
其中：
数据文件空间：即用户数据所占用的空间，SQL Server 的数据文件空间都是预分配的，所以您每建一个 DATABASE 都会占用近500MB空间用以存储您的数据。
事务日志文件空间：SQL Server 的每个 DATABASE 都有一个日志文件，数据库完整模式下会将事务日志写入日志文件。
临时表文件：SQL Server 的 TEMPDB 占用的文件，复杂查询产生的临时表。
系统库：SQLServer 数据库实例系统库所产生的文件。
是
