A dagger is an off-hand weapon. A character can use a dagger to make attacks even while holding another one-handed weapon in the other hand, and can use the other one-handed weapon to make attacks even if it isn't an off-hand weapon. A dagger is also a light thrown weapon, so a character can throw it as a ranged attack.
All classes have weapon proficiency with the dagger as a class trait. Swordmages have implement proficiency with light blades, including the dagger. Monks and sorcerers also have implement proficiency with the dagger.
