In brief: Very similar

Some substances only dissolve in water like salt, some only in oils like fats.
A soap is one molecule with two faces, one is like water and dissolves watery items, and the other face is like fat and dissolves oily items. That's why soaps are so useful, they can dissolve such a wide range. Detergents are a type of soap that works very well in mineral laden waters like hard water.
