There is lots of talk about DAMA-DMBOK2 and DCAM and this can be confusing for people who are new to data governance and data management. There are many definitions describing what data governance is. For example Wikipedia states
'Data governance is a term used on both a macro and a micro level. The former is a political concept and forms part of international relations and Internet governance; the latter is a data management concept and forms part of corporate data governance.'
I came across this article Data Management and Data Governance in a Nutshell which has a useful concept map of data management and data governance definitions. DAMA and DCAM are fairly well aligned now.
