Text - Order

Data System Architecture


Order in text data is defined by:

Order in text is known as collation

See therefore the collation page for the whole picture


Language directionality

The language directionality (known also as character order) specifies the axis and direction of the text readability (ie Left To Write, Write To Left, Top to Bottom).

Character Set Order

There are two main groups of encoding schemes:

  • on Unix machines, the scheme is usually ASCII,
  • whereas the majority of mainframes use EBCDIC.


ASCII sorts as follows:

  • numbers
  • upper case characters (A-Z)
  • lower case characters (a-z)


EBCDIC sorts in the reverse order:

  • lower case characters (a-z)
  • upper case characters (A-Z)
  • numbers
