Relasi adalah aturan yang memasangkan anggota suatu himpunan ke himpunan lainnya tanpa syarat khusus (bebas menghubungkan berapa pun pasangan).<br>
<b>Contoh:</b> Himpunan Anak {Ani, Boni} dihubungkan ke Himpunan Warna {Merah, Biru, Hijau} dengan relasi "menyukai warna". Satu anak boleh suka lebih dari satu warna.

Diagram panah menyajikan relasi dengan menghubungkan anggota himpunan A (Domain) ke himpunan B (Kodomain) menggunakan anak panah.<br>
<b>Contoh:</b> Himpunan A = {1, 2, 3} dihubungkan ke B = {2, 4, 6} dengan aturan relasi <em>"setengah dari"</em>. Maka 1 dipanah ke 2, 2 dipanah ke 4, dan 3 dipanah ke 6.
