These three acronyms refer to Digital Asset Management, Media Asset Management, and Production Asset Management. All three are concerned with better management and maintenance of your assets (files, videos, images, infographics, documents, etc.). Their difference is in emphasis. DAM focuses on metadata tagging so that you can find assets faster. PAM is all about collaborative features that help you streamline the production of assets while MAM is concerned with unique workflows for multimedia files. Pics.io DAM solution collects all 3 under one umbrella.
