我的数据库中有以下图表：

在Node 1有一个保密要求，我需要在Node 4设置一个条件。我需要根据节点1的值设置评级在节点4的值。我对如何做到这一点一无所知。以下是我的创建脚本：

CREATE 
(App4:App {name:          'Consumer Banking Portal No Review',  confidential_requirement: 'high', integrity_requirement: 'high', availability_requirement: 'high',           inherent_risk_rating: 'critical', crown_jewel_application: 'yes', internet_facing: 'yes', average_transaction: '100', max_number_of_daily_transaction: '200',         number_of_pii_record: '5000' }),
(feat1: FEATURE {name: "Update_Profile", desc: "update customer profile"}),
(gf_query: GENERIC_FEAT {name: "QUERY_INFO",  desc: "retrieve info"}),
(t_auth_read: THREAT {name: "Auth_Read_t", desc: "Compromise authorization in query info", impact: "Information Disclosure", rating: ""}),
(App4)-[:HAS]->(feat1),
(feat1)-[:HAS]->(gf_query),
(gf_query)-[:HAS]->(t_auth_read);
