    \n
  1. Simple atribute : entity yang atributnya tidak dapat dibagi menjadi bagian <\/span>yang lebih kecil.<\/span><\/li>\n

  3. Single<\/span>–<\/span>valued attribute : entity yang atributnya hanya dapat berisisatu <\/span>nilai. Misal nomer induk pekerja.<\/span><\/li>\n
  4. Multivalued attribute : entity yang atributnya dapat berisi nol, satu atau <\/span>lebih dari satu nilai. Misalnya : atrib<\/span>ut telephon, bisa jadi seorang pekerja <\/span>mempunyai nol, satu, atau lebih telephon.<\/span><\/li>\n
  5. Atribut<\/span> turunan<\/span> :<\/span> entity<\/span> yang<\/span> atributnya<\/span> dapat<\/span> diturunkan<\/span> dari <\/span>atributlainnya.
