Question

我创建了一些使用Oracle SQL具有相关表的表。我的讲师希望我将这些迁移到一个mongodb，我在网上搜索，但我对他们正在做的事情一无所知。我知道如何设置mongodb并获得连接，但我不知道如何迁移到mongodb。

这是我创建的表格

CREATE TABLE TBL_EVENT_ORDER
 (
  ORDER_ID INT CONSTRAINT PK_TBL_EVENT_ORDER     
  PRIMARY KEY,
  CLIENT_ID VARCHAR2(10),
  CONSTRAINT FK_CLIENT FOREIGN KEY (CLIENT_ID) REFERENCES
  TBL_CLIENT(CLIENT_ID),
  ORDER_DATE DATE DEFAULT SYSDATE,
  EVENT_ID INT DEFAULT 1,
  CONSTRAINT FK_WINE_EVENT FOREIGN KEY (EVENT_ID) REFERENCES
  TBL_WINE_EVENT(EVENT_ID)
 );

CREATE INDEX IDX_FK_CLIENT_ID_TBL_CLIENT ON TBL_EVENT_ORDER(CLIENT_ID);
INSERT INTO TBL_EVENT_ORDER VALUES
(1,'1',DEFAULT,'1');
INSERT INTO TBL_EVENT_ORDER VALUES
(2,'2',DEFAULT,'1');
INSERT INTO TBL_EVENT_ORDER VALUES
(3,'3',DEFAULT,'1');
INSERT INTO TBL_EVENT_ORDER VALUES
(4,'4',DEFAULT,'1');


CREATE TABLE TBL_WINE
 (
   WINE_ID INT CONSTRAINT PK_WINE PRIMARY KEY,
   WINE_NAME VARCHAR2(20),
   PRICE NUMBER(6,2) CONSTRAINT NN_PRICE NOT NULL,
   WINE_TYPE VARCHAR2(20) CONSTRAINT NN_WINE_TYPE NOT NULL,
   WINE_YEAR INT CONSTRAINT NN_WINE_AGE NOT NULL,
   WINE_COUNTRY VARCHAR2(20),
   WINE_REGION VARCHAR2(20)
 );

INSERT INTO TBL_WINE VALUES
(1,'AGUILA RED',100.50,'BORDEAUX',2010,'COUNTRY1','REGION1');
INSERT INTO TBL_WINE VALUES
(2,'CLOUD BAY',150,'BORDEAUX',2010,'COUNTRY2','REGION2');
INSERT INTO TBL_WINE VALUES
(3,'HARLAN ESTATE',175.50,'BORDEAUX',2010,'COUNTRY3','REGION3');
INSERT INTO TBL_WINE VALUES
(4,'KRUG',200,'BORDEAUX',2010,'COUNTRY4','REGION4');

CREATE TABLE TBL_ORDER_DETAIL
 (
  ORDER_ID INT,
  WINE_ID INT,
  CONSTRAINT PK_ORDER_DETAIL PRIMARY KEY (ORDER_ID, WINE_ID),
  CONSTRAINT FK_EVENT_ORDER FOREIGN KEY (ORDER_ID) REFERENCES      
  TBL_EVENT_ORDER(ORDER_ID),
  ORDER_QTY INT CONSTRAINT NN_ORDER_QTY NOT NULL,
  UNIT_PRICE NUMBER(6,2),
  EXCLUSIVE_IMPORT CHAR(1)
);

CREATE INDEX IDX_FK_ORDER_ID_EVENT_ORDER ON TBL_ORDER_DETAIL(ORDER_ID);
CREATE INDEX IDX_FK_WINE_ID_WINE ON TBL_ORDER_DETAIL(WINE_ID);

INSERT INTO TBL_ORDER_DETAIL VALUES
(1,1,3,100.50,'N');
INSERT INTO TBL_ORDER_DETAIL VALUES
(2,2,1,150,'N');
INSERT INTO TBL_ORDER_DETAIL VALUES
(3,3,4,175.50,'N');
INSERT INTO TBL_ORDER_DETAIL VALUES
(4,4,2,200,'Y');

如何将oracle sql表迁移到mongodb？
