我需要以以下方式提取数据
Compare_Result Association_Type_name Association_Role
Type in Dev,but not Prod ProcessingSite Null
Role in Dev,but not Prod ProcessingSite MoodedActivity
Role in Dev,but not Prod Specimen ProductRelationship
要求：我需要比较开发和生产。如果生产中不存在任何关联类型或关联角色，那么我需要返回一条消息，例如“在开发中找到的类型对象，但不是生产”
任何人都可以给我一个想法。

例子
让我们假设我有以下结构
Dictionary_area
development
Association_Dictionary
ProcessingSite(type1)
TreatingSite(role1)
MoodedActivity(role2)
MaterialName(role3)
PerformedClass(type2)
RegulatoryAssessment(role1)
Submission(role2)
Mooded(role3)
Specimen(type3)
class13th(role1)
ProductRelationship(role2)
production
Association_Dictionary
ProcessingSite(type1)
TreatingSite(role1)
MaterialName(role2)
BiologicEntityGroup(type2)
StudyInvestigator(role1)
Assessor(role2)
Distributor(role3)
Specimen (type3)
class13th(role1)
ProcessingSite 是一个关联类型，它有 3 个关联角色。我们可以在生产中观察到相同的关联类型，但 MoodedActivity(association_role) 不可用。在这种情况下，我们需要返回“在开发中找到类型对象，但不是在生产中找到”。
表信息
节点：此表将包含节点和父节点信息。例如，如果开发对象有一些像 100 这样的节点，它的父节点是 99。
对象：对象信息。
object_types：object_type 信息。例如 ProcessingSite object_type 是“Association_Type”。
