@Matt H: 这种方法是否被视为“AEV”或仅仅是“标准关系”?
So because i will have many users in many dif industries that will want to add their own custom fields to a number of different tables (contacts, transactions, events, etc) i am assuming that i would need the customfield table to have a user_fk/id or company fk/id, a related table fk/id, an id, and a field name? Am i on the right track? Then in the need to create a 2nd table to hold the data for each custom field buy having a customfield fk/id, customer fk/id, id and a data field to hold the actual data. Is this correct?
因此,一旦在接触表中增加两个表格,我如何增加这些表格,这样,它就象一个大的用户表格,而不是三个表格?
Thanks again for you help.

after much research i have found that most people who wish to accomplish this are using document databases not relational databases.
