Five Security Features of RDBMS
... One of the advantages of commercial databases like Oracle, DB2, SQL Server etc.. is that their internal architecture is highly proprietary making it difficult for other third party tools to decipher meaning out of them. For example the above databases support CLOB, BLOB storage types which are typic ...
