mysql - 简化/速记 SQL 数据定义语言？

Question

有些人喜欢以简单的文本方式描述他们的数据库结构，而不是使用CREATE TABLE 语句。几个例子:

• Foreign key as Primary key
• Multiple Primary Keys as single foreign key
• How can I set up a database schema where there are two concurrent many-many relationships?
• primary key and foreign key
• How should I set up database tables for this order situation

您知道有什么软件可以将这种速记符号转换为实际的 SQL 语句吗？

其实我刚刚完成了一个php脚本，它就是这样做的，但我希望那里有更专业的东西......

示例输入:

= ID id P AI

person
  ID
  mother_id -> person
  father_id -> person
  !FK mother_id, father_id -> family U:C, D:C

family
  P female_id -> person
  P male_id   -> person

输出:

CREATE TABLE IF NOT EXISTS person (
   id         INT NOT NULL AUTO_INCREMENT,
   mother_id  INT NOT NULL,
   father_id  INT NOT NULL,
   PRIMARY KEY ( id )
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;

CREATE TABLE IF NOT EXISTS family (
   female_id  INT NOT NULL,
   male_id    INT NOT NULL,
   PRIMARY KEY ( female_id, male_id )
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

ALTER TABLE person ADD FOREIGN KEY ( mother_id ) REFERENCES person( id );
ALTER TABLE person ADD FOREIGN KEY ( father_id ) REFERENCES person( id );
ALTER TABLE person ADD FOREIGN KEY ( mother_id, father_id ) REFERENCES family( female_id, male_id ) ON DELETE CASCADE ON UPDATE CASCADE;

ALTER TABLE family ADD FOREIGN KEY ( female_id ) REFERENCES person( id );
ALTER TABLE family ADD FOREIGN KEY ( male_id ) REFERENCES person( id );
