The BLOB replaces the LONG data type which was the standard data type for any binary data. The LONG data type had a number of key limitations including only one being allowed per table and minimal support for controlling its storage. As of Oracle11g a BLOB does not have a maximum size.

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar?
