Oracle 数据库使用表空间中的数据段保存表数据。 As explained in "User Segments", a segment contains extents made up of data blocks. 如"用户段"所述，段包含由数据块组成的扩展盘区。 The data segment for a table (or cluster data segment, when dealing with a table cluster) is located in either the defau...
表压缩 The database can use table compression to reduce the amount of storage required for the table. 数据库可以使用表压缩来消除数据块中的重复值。 Compression saves disk space, reduces memory use in the database buffer cache, and in some cases speeds query execution. Table compression is transparent to database applications. 对于数据高度冗余的表，压缩可以节省磁盘空间，减少数据库高速缓存中的内存使...
