A fundamental component of a data model dataset. Constraints filter out irrelevant events and narrow down the dataset that the dataset represents.
Constraint definitions differ according to the object type. They can be simple searches (root event datasets, all child datasets), complex searches (root search datasets), or transaction definitions (root transaction datasets).
Each child object inherits the constraints of its parent object and includes a new constraint that ensures it represents a subset of the data covered by its parent dataset.
