A.7.4.

What is the difference between the Oracle Data Dictionary and MySQLINFORMATION_SCHEMA?

Both Oracle and MySQL provide metadata in tables. However, Oracle and MySQL use different table names and column names. The MySQL implementation is more similar to those found in DB2 and SQL Server, which also supportINFORMATION_SCHEMA as defined in the SQL standard.

A.7.5.

Can I add to or otherwise modify the tables found in theINFORMATION_SCHEMA database?

No. Since applications may rely on a certain standard structure, this should not be modified. For this reason,we cannot support bugs or other issues which result from modifyingINFORMATION_SCHEMA tables or data.
