    解析: Oracle存储模型,逻辑结构在左,物理结构在右。  逻辑结构由大到小database-->tablespace-->segment-->extent-->oracle data block 
    1、数据库是由多个表空间组成。  
    2、每个表空间只属于一个数据库,包含一个或多个数据文件,每个数据文件只属于一个表空间, 
    3、每个段包括一个或多个extents区  
    4、extent(区),由相邻的数据块的组成。 
    5、块BLOCK:是数据库中最小的I/O单元,db_block_size

  • 第8题:

    Which three statements are true about logical structures of the Oracle database()
    A

    Each segment contains one or more extents.

    B

    Multiple tablespaces can share a single data file.

    C

    A data block is the smallest unit of input/output (I/O) in data files.

    D

    It is possible to have tablespaces of different block sizes in a database.

    E

    Each data block in the database always corresponds to one operating system block.


    正确答案: A,C,D
    解析: A答案:每个段包含一个或多个区,正确。 
    B答案:一个数据文件只能属于一个表空间,故错误。 
    C答案:Oracle data block是最小的I/O单位,正确 
    D答案:可以是不同的块大小,需要指名非标准块的位置。 
    E答案:每个数据库里面的数据库对应一个或多个操作系统块,故E错误。
