用JSON表示数据库Schema：employee与car表结构转换需求

没问题，我把你给出的employee和car两张表的结构转换成了清晰易读的JSON格式，你可以直接用这个来表示你的数据库Schema：

{
  "tables": [
    {
      "name": "employee",
      "columns": [
        {"col_name": "eid", "data_type": "int"},
        {"col_name": "name", "data_type": "string"},
        {"col_name": "salary", "data_type": "int"},
        {"col_name": "destination", "data_type": "string"}
      ]
    },
    {
      "name": "car",
      "columns": [
        {"col_name": "cid", "data_type": "int"},
        {"col_name": "name", "data_type": "string"},
        {"col_name": "model", "data_type": "string"},
        {"col_name": "cylinders", "data_type": "int"},
        {"col_name": "price", "data_type": "int"}
      ]
    }
  ]
}

这个结构用tables数组统一管理所有表信息，每个表对象包含表名和对应的列详情，每一列都明确映射了字段名和数据类型，不管是用于文档记录还是程序解析都很方便。
