It is a collection of character data in a database management system, usually stored in a separate location that is referenced in the table itself. Oracle and IBM Db2 provide a construct explicitly named CLOB, [1] [2] and the majority of other database systems support some form of the concept, often labeled as text, memo or long character fields.

A string of seven characters. In computing and telecommunications, a character is the internal representation of a character (symbol) used within a computer or system. Examples of characters include letters, numerical digits, punctuation marks (such as "." or "-"), and whitespace.
MIME defines two different mechanisms for encoding non-ASCII characters in email, depending on whether the characters are in email headers (such as the "Subject:"), or in the text body of the message; in both cases, the original character set is identified as well as a transfer encoding.
The same character in the linguistic sense, can be mapped to one or more computer characters depending on the character encoding. For example, the Unicode standard maps the same letters from Latin, Greek, and Hebrew alphabets to various duplicate code points in the Letterlike Symbols and other blocks, often meant to represent specific ...
