An operator used to assert that two (or more) parts of a concept definition or expression constraint must both be true.
Notes
- Conjunction can be represented by the AND operator. A conjunction of A with B, means that both A AND B must be true.
- Conjunction gives the same result as an intersection between the set of concepts or expressions for which A is true and the set of concepts or expressions for which B is true.
Example
The following expression constraint is satisfied by clinical findings which are subtypes of both 19829001 | Disorder of lung (disorder)| AND 301867009 | Edema of trunk (disorder)| .
