| Business Data Model Data Model |
| Description | A relationship between a composite activity and a component activity that comprises it, that is, parent and child activities, where all these activities are part of a global library of activities. For example: A battery of tests may be composed of multiple routine labs that are always ordered together as a group. A glucose tolerance test which is composed of administering glucose and taking multiple timed blood samples which are then tested for glucose. This class helps represent an AND relationship between siblings with the same parent activity. |

Activity Join Code
| Description | A coded value specifying whether, and how, a specific activity in a set of parallel activities should come together before subsequent activities can begin. For example: Wait for this activity to complete before the subsequent activity. Terminate this activity as soon as all parallel "wait" activities are completed (and if this activity hasn't started yet, don't start it at all). Continue this activity after all "wait" activities complete, but don't wait for it to complete before beginning subsequent activities. |

Pause Qty
| Description | The time falling within minimum and maximum bounds that specifies the elapsed time between when an activity is ready for execution and the beginning of the execution. For example: If you take a blood sample 15 minutes after administration of a study drug, or measure blood glucose two hours after each meal, the pause quantity is 15 minutes and two hours. |

Priority Seq
| Description | An integer specifying the relative sequential or temporal ordering of this relationship among other similar relationships having the same source. In a course of treatment (a composite activity) that is composed of a chemotherapy activity and a radiotherapy activity, the sequence number indicates which component activity precedes the other. |
