# Definition
When connecting to external systems, it is necessary to establish a mapping relationship with the storage objects of the external system. This is what **Table Id** refers to.
# 定义
# Example
To be compatible with most external systems, the Table Id is represented by a 3-tuple : (namespace, schemaName, tableName).
Connectors should establish the mapping between Table Id and storage objects in external systems.
