假设我有类似对象的数据记录:
$article = array(
'title' => '',
'tagline' => '',
'content' => '',
'stats' => array(
'words' => 0,
'paragraphs' => 0,
'tables' => 0
),
'references' => array(
'reference 1',
'reference 2',
'reference 3'
),
'attachments' => array(
'images' => array(
'image 1',
'image s'
),
'videos' => array(
'video 1',
'video 2'
)
)
);
我的问题是如何在关系数据库中存储这个数据记录数组?我该如何设计表结构?
我知道我总是可以设置stats_words,stats_paragraphs等平面字段,但是还有更多的结构方法吗?而不是将JSON或序列化字符串存储在单个字段中....
谢谢!
答案 0 :(得分:0)
例如这样:
article
ID
title _
tagline _
content ___
stat_words
stat_paragraphs
stat_tables
article_reference
ID
article_id -> article
reference _
article_attachment
ID
article_id -> article
att_type // image or video
path _
title _
(_
表示varchar / text字段,其他字段是数字)
或者作为MySQL DDL:
CREATE TABLE IF NOT EXISTS article (
id INT NOT NULL AUTO_INCREMENT,
title VARCHAR(255) NOT NULL,
tagline VARCHAR(255) NOT NULL,
content MEDIUMTEXT NOT NULL,
stat_words INT NOT NULL,
stat_paragraphs INT NOT NULL,
stat_tables INT NOT NULL,
PRIMARY KEY ( id )
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;
CREATE TABLE IF NOT EXISTS article_reference (
id INT NOT NULL AUTO_INCREMENT,
article_id INT NOT NULL,
reference VARCHAR(255) NOT NULL,
PRIMARY KEY ( id ),
FOREIGN KEY ( article_id ) REFERENCES article( id )
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;
CREATE TABLE IF NOT EXISTS article_attachment (
id INT NOT NULL AUTO_INCREMENT,
article_id INT NOT NULL,
att_type INT NOT NULL,
path VARCHAR(255) NOT NULL,
title VARCHAR(255) NOT NULL,
PRIMARY KEY ( id ),
FOREIGN KEY ( article_id ) REFERENCES article( id )
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;
