For a one-to-many relationship, where the “many” has a small number of known values, relationships can be stored as bitmasks in the parent table as an integer, replacing the need for an additional table.

Say we have a table Person and we’d like to know how many Continents a person has visited. We’d start by assigning each Continent an “orthogonal” bit value. In C#, an enum is a good choice for this:

[Flags]
public enum JobAdvertisingRegion
{
    NorthAmerica = 1,              // or 1 << 0
 SouthAmerica = 2, // 1 &lt;&lt; 1
