以下是一些常见的层次结构数据库的例子：

1. MySQL (Microsoft Azure Marketplace SQL Server):

• 数据库：MySQL

2. PostgreSQL (Microsoft SQL Server):

• 数据库：PostgreSQL
• 表：REPAIRD TABLE PostgreSQL( id INT, name VARCHAR(50), age INT, email VARCHAR(255), address VARCHAR(255), database INT, created at (REPAIRD TABLE pd ON PROVIDER IDENTIFIED PRIMARY KEY, created at (REPAIRD TABLE pd ON PROVIDER IDENTIFIED PRIMARY KEY, created at (REPAIRD TABLE pd ON PROVIDER IDENTIFIED PRIMARY KEY, created at (REPAIRD TABLE pd ON PROVIDER IDENTIFIED PRIMARY KEY, created at (REPAIRD TABLE pd ON PROVIDER IDENTIFIED PRIMARY KEY, created at (REPAIRD TABLE pd ON PROVIDER IDENTIFIED PRIMARY KEY, created at (REPAIRD TABLE pd ON PROVIDER IDENTIFIED PRIMARY KEY, created at (REPAIRD TABLE pd ON PROVIDER IDENTIFIED PRIMARY KEY, created at (REPAIRD TABLE pd ON PROVIDER IDENTIFIED PRIMARY KEY, created at (REPAIRD TABLE pd ON PROVIDER IDENTIFIED PRIMARY KEY, created at (REPAIRD TABLE pd ON PROVIDER IDENTIFIED PRIMARY KEY, created at (REPAIRD TABLE pd ON PROVIDER IDENTIFIED PRIMARY KEY,
