What is ISO 27001?

Methodology for ISMS, framework, process, etc. I do not know there are these priorities.
When I Management System has been created, the first process is created, and the second methodology, know that the third framework is created.
What is really in their relationships, or what not wonder.

Answer:
I am sorry but I am not sure if I have understood your question, but for the ISO 27001 is not relevant the relationships that you have mentioned. The central idea of an ISMS based on ISO 27001 is the risk management, so this article can be interesting for you “The basic logic of ISO 27001: How does information security work?” : https://advisera.com/27001academy/knowledgebase/the-basic-logic-of-iso-27001-how-does-information-security-work/
