我之前曾问过这个问题（How to store a Tree Of Life in MySQL? (Phylum, Class, Order, Family, etc)）我正在使用MySQL但是在有人建议使用MongoDB后，我决定环顾四周并安装Couchbase。 （有趣的是，geraldss在我安装之后在我上一个问题的评论中建议使用Couchbase。）
我会在文件中为每条鱼存储王国，门，等等。但我也希望有文档来帮助进行多级下拉。
我希望第一个下拉列表是5个王国，然后下一个下拉列表将填充此王国的Phylum。然后第三个下拉列表将填充此Phylum类的列表，依此类推。< / p>
现在我正在努力寻找最好的实用方法来存储它。
我应该创建一个名为分类法的单个巨大文档，还是应该创建多个文档，比如每个Phylum（仍然是大文档）或其他什么？
帮助我创建文档的小PHP数组示例：
"Fungi" => array(
"type"=>"kingdom",
"origin" => "Latin, derived from Greek - sp(h)onges, sponges",
"description" => "Obtain food through absorption, excrete enzymes for digestion",
"example" => "molds, mushrooms, lichens",
"Phylum" => array(),
),
"Plantae" => array(
"type"=>"kingdom",
"origin" => "Latin - plant",
"description" => "Multicellular organisms that are autotrophic",
"example" => "mosses, ferns, grasses, flowers, trees.",
"Phylum" => array(),
),
"Animalia" => array(
"type"=>"kingdom",
"origin" => "Latin - breath, soul",
"description" => "Multicellular organisms that develop from the fertilization of an egg by a sperm",
"example" => "sponges, worms, insects, fish, birds, humans",
"Phylum" => array( //32 total, 12 here
"Porifera" => array(
"name" => "Porifera",
"type" => "Phylum",
"origin" => "Latin - to bear pores",
"description" => "Sponges",
),
"Cnidaria" => array(
"name" => "Cnidaria",
"type" => "Phylum",
"origin" => "Greek - nettle",
"description" => "",
"Class" => array(
"Hydrozoa" => array(
"name" => "Hydrozoa",
"description" => "Hydras",
"Order" => array( //Multiple Order
"Family" => array( //Multiple Family for each Order
"Genus" => array( //Multiple Genus for each Family
),
),
),
),
我该怎么办？创建一个单独的文档会是一个好方法吗？你会怎么存储这个？
（请不要关闭这个问题，我正在努力将我的思路从关系转向基于文档的数据库，而我正在努力解决这个问题）
