18. NCLOB
The character set defined by the international character set of the database can be used to store character-based data of the Unicode type only. A maximum of 4 GB of data can be stored, which is larger than the maximum data that can be stored in the oracle10gb database. This is also a factor in the size of blocks specified by the database (~ 4 GB * data block size ).

19. BLOB
A large binary object that can store up to 4 GB of data is larger than the maximum data that can be stored in the oracle10gb database. This is also a factor in the size of blocks specified by the database (~ 4 GB * database block size ).

20. BFILE
