HBASE嵌套数据模型

HBASE版本：0.94.10

NOSQL为初级保健系统设计数据模型的新功能。我有标准化的样本数据库关系模型，例如HBASE-0.94.0

Patient table: 

============ 

1) Patient_id - PK 

2) Added_BY 

3) Gender 

4) Usual_GP 

,

,

,

,

对于上面的标准化数据模型，我在下面创建了示例NoSQL数据模型，我希望数据模型适用于基于文档的NoSQL。需要将下面的数据模型转换为基于HBASE列的数据模型，请帮助我

Patient :{Patient_id:22, 

              Added_by:Doctor1, 

              Gender:Male, 

              UsualGP: Doctor2, 

              PatName:[ 

              {NameType:Usual, FirstName:Hari, LastName:prasad,Middlename:' '}, 

              {NameType:Other, FirstName:John,LastName:prasad,Middlename:kenndy}  

              ] 

              PatAddr:[ 

              {AddType:Usual, Line1:2, Line2:Harrington road, Line3: near central, Line4:Newyork,Line5:NY008}, 

              {AddType:Tmp, Line1:2, Line2:Mylapore road, Line3: near Zoo, Line4:WashingtonDC,Line5:WA00098} 

              ] 

              PatPhone:[ 

              {PhoneType:Usual, Phoneno:4453443344, ext:099}, 

              {PhoneType:Tmp, Phoneno:9198332342343, ext:} 

              ] 

              PatMedication:[ 

              {MedStardate:'01/01/2013', MedEndDate:'', Code:'Snomode', MedDesc:'Paracetmol', DosDet:'Take 2 daily', Noauth: 5, Issue: 3}, 

              {MedStardate:'01/05/2013', MedEndDate:'01/05/2013', Code:'readcode', MedDesc:'Avil', DosDet:'Take 1 daily', Noauth: 3, Issue: 1}, 

              {MedStardate:'01/10/2013', MedEndDate:'24/10/13', Code:'readcode', MedDesc:'Metacin', DosDet:'Take 2 daily', Noauth: 5, Issue: 3}, 

              ] 

             }

正如评论中所说，HBase用于非关系数据。但是，您仍然可以将其用于此目的。首先，应该定义柱族。不需要列名称，因为它是列形式的

将这些列放在同一列族中可以提高性能。因此，一个柱族就好了。除此之外，缩短列和列族名称也是另一个性能问题。如果可以，请使用一个或两个字母命名这些列和列变量

但是，不能按原样使用外键。我的意思是，可以将另一个表的id存储在列中，但不能直接检查它是否存在。相反，您应该转到此表并手动检查它

我希望这个解释能对你有所帮助。查看更多详细信息。

欢迎来到SO，请先阅读：也向我们展示您的尝试。为什么是HBase？！它是为非关系数据库使用而制作的！。。
