Suppose i have a relationship 1 to N, for example Student , College. Student Attributes: Name,Surname,CollegeFKey, College attributes: CollegeKey,Other,Other.
Suppose that i have a program which read students and Exams from a plain text file. And on this file i have duplicated Colleges and Duplicated Studens. Like in denormalized tabels: CollegeId,Other,Other,Name,Surname,CollegeFkey. 1,x,y,Mike,M,1 1,x,y,R,P,1 ... ... you see i have to check in this case always that in my normalized db, i have still not inserted in the Table College 2 times the key 1, how can i solve this in Hbase ? i mean if i have 1000.. tables and rows i dont want check for every Primary Key and then for every Fk if it was inserted ok ? how can i solve that ? -- [email protected] Inviato con Sparrow (http://www.sparrowmailapp.com/?sig)
