Collation sensitivity is used to define the rules for sorting and comparing the strings of character data. The basic rule for sorting a character data are correct character sequence, Case-sensitivity, character width, and accent marks, etc.
Different types of collation sensitivity :
Case Sensitivity : Case sensitivity defines every character with a unique value, as alphabet characters A and a are treated individually, as they have different ASCII values for a computer language
Accent sensitivity : Accent sensitivity is related that whether the accent is off or not, as a and á both should be treated differently
Kana sensitivity : Kana sensitivity defines the difference between two Japanese words: Hiragana and Katakana
Width sensitivity : It differentiates between a single-byte character (half- width) and representation of the double-byte character of the same character
