This is my first real crack at making a database in Third Normal Form. I managed to create the DDL script ok (I had the logical model verified to 3NF before I went ahead and built the script) but I get a whole lot of errors I am unsure of fixing. I may have bitten more than I can chew for this particular case but I don't want to give up - it's a big learning curve for me and with some help I can get past this and move on.

First of all, here is my DDL script:

-- This sql script creates the structure.
-- of the rugby club database.

DROP DATABASE IF EXISTS database_rugby;

CREATE DATABASE database_rugby;

USE database_rugby;

And here's the logical model (if anyone sees problems with any of the relationships - in particular, the many:many relationships, please let me know).

I apologise if I gave too much information, but I thought if I gave all this information it would make things easier on people that want to help me out. I have spent a good 3 hours making adjustments to the DDL script but after spending that long I realised I need someone with more experience to help me. I've showed the logical model to someone with industry experience in databases and they believe it conforms to 3NF. Doing the conceptual and logical models wasn't so bad for myself, it was trying to convert the logical model to working script and successfully inserting data (I want to insert at least 10 records for each table) that has become the biggest hurdle.

Thanks in advance!


回答1:


You have to add this statement as well Add it at the top of your dump file 

SET foreign_key_checks = 0;

This will disable the foreign key checks and you can easily execute the dump file

and add another statement at the bottom of your dump file to enable back the foreign key check

SET foreign_key_checks = 1;

The Foreign Key constraints you have between person (the Superclass) and player, parent and coach (the Subclasses) are not defining 1:1 relationships. Here is a possible solution: 

-- Create the "person" table.
--
-- This table has one:one relationships
-- with the parent, coach and player 
-- tables.
DROP TABLE IF EXISTS `person` ;                --- no change
CREATE TABLE `person` (
  `personID` INT(5) NOT NULL AUTO_INCREMENT ,
  --- ...
  --- several columns omitted for clarity
  --- ...
  PRIMARY KEY (`personID`))
ENGINE = InnoDB;

The parent table can have the personID both as Primary and Foreign Key to person:

-- Create the "parent" table.
DROP TABLE IF EXISTS `parent` ;
CREATE TABLE `parent` (
  --- `parentID` INT(5) NOT NULL ,             --- removed

  `personID` INT(5) NOT NULL ,

  --- PRIMARY KEY (`parentID`, `personID`),    --- removed

  PRIMARY KEY (`personID`),                    --- this part only as PK
                                               --- which is also a FK
  FOREIGN KEY (`personID`)                     --- as previously (no change here)
    REFERENCES `person` (`personID`)
    ON DELETE CASCADE 
    ON UPDATE CASCADE)
ENGINE = InnoDB;

And similarly for player:

-- Create the "school" table.
-- omitted for clarity
--
--    
-- Create the "player" table.
--
-- Inherits fields from the "person"
-- and "school" tables.
DROP TABLE IF EXISTS `player` ;
CREATE TABLE `player` (
  --- `playerID` INT(5) NOT NULL ,             --- removed
  `personID` INT(5) NOT NULL ,
  `schoolID` INT(5) NOT NULL ,
  PRIMARY KEY (`personID`),                    --- Primary Key
  FOREIGN KEY (`personID`)                     --- that is also Foreign Key
    REFERENCES `person` (`personID`)
    ON DELETE CASCADE 
    ON UPDATE CASCADE, 
  FOREIGN KEY (`schoolID`)
    REFERENCES `school` (`schoolID`)
    ON DELETE CASCADE
    ON UPDATE CASCADE)
ENGINE = InnoDB;

The same should be done to the coach table.

Note that the above solution allows a person to be both a player and a parent or both a parent and a coach. If you want to restrict a row of the superclass (person) table to be only one the subclass tables, it would have to be a slightly different approach.
