-# 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.
+**Table Id**主要用来建立连接器与外部系统存储对象的映射关系，所有外部系统的数据集合都可以映射到一个专用的
+Table Id。
 
-The following table lists the parts in table Id of different data systems:
+# 示例
 
-| data system           | parts in tableId         | String example      |
-|-----------------------|--------------------------|---------------------|
-| Oracle/PostgreSQL     | database, schema, table  | mydb.default.orders |
-| MySQL/Doris/StarRocks | database, table          | mydb.orders         |
-| Kafka                 | topic                    | orders              |
+为了兼容绝大部分的外部数据系统，Table Id 由命名空间、模式名、表名3个部分组成，即(namespace, schemaName, tableName)。不同的外部系统Table Id的构造参数可能不同，比如Oracle数据库的Table Id包含命名空间(database)、模式名(schema)和表名(table)，Doris的Table Id包含模式名(database)和表名(table)，Kafka的Table Id仅包含表名(topic)。
+
+下面是一些常见的外部系统及其对应的 Table Id 格式：

+| Oracle/PostgreSQL     | database, schema, table | mydb.default.orders |
+| MySQL/Doris/StarRocks | database, table         | mydb.orders         |
+| Kafka                 | topic                   | orders              |
