Some of the patterns used in the lower tier were:

- get persistent attribute (ex. getStartDate)

- get derived attribute (ex. getAge)

- set persistent attribute (ex. setStartDate)

- relate (two objects together) (ex. relateActivityWithNatureIdStartDate)

- get related (ex. getRelatedActivitiesWith NatureId)

- isEffective (ex. isEffectiveAsOf)

- createWith...(ex. createWithTypeIdStartDate)

- findRelated...(ex. findAgreementsRelatedToActivtyWithNatureId)

- findBy...(ex. findByAgreementForwardWithAgreementTypeIdReverseNatureId)
