Hi,
I have a database of about 20,000 business customers that is growing. But many of these customers are part of a larger business entity and I need to identify that. They are connected through names of owners listed on the customers. However, not all customers under the main entity have same owners. If they have even one common owner, I will assume that they are part of that major entity. For example: if I have 10 customers C1, C2…C10 and 10 owners O1,O2,O10. They are connected as below.
C1: O1, O2, O3
C2: O2, O4, O5
C3: O4, O5, O6
C4: O7
C5: O6, O7
C6: O8
C7: O8, O10
C8: O9, O10
C9: O8
C10: O10I can tell that there are 2 major groups: Group 1 includes C1, C2, C3, C4, C5 and Group 2 includes C6, C7, C8, C9, C10. I would like to use an algorithm that does this or create one in SQL? May be an open source tool that has capability? Any suggestions? Please let me know if you need more clarity.
PS: There are other ways to identify if two business customers are part of the same entity for example through their mailing addresses, email address, phone numbers and such. If I can introduce multiple criteria into my groups that would be ideal, but I can do with just one for now.Thanks in advance.
