What are the CRM systems with my subordinate tables?

Question

Web development

Hello
Tell me some CRM-system in which you can add your own invented subordinate tables to the records of contacts (and others).
For example, I want to add to the client a list of dishes that he likes (with a price and where they are sold). You can, of course, put them in a simple field, but then filtering and generally servicing them is much more difficult.

Answer 1

See www.sysclick.ru
Any data structure. Configurable without programming.

Answer 2

Before asking a question, you yourself have just now set yourself a priority task - to draw up a client profile.
Having compiled the questionnaire, leave only those items that have informational and practical value. And only then ask a question with a ready-made questionnaire template.
