What is Data lifecycle management (or DLM for short) ? It's about handling data's full lifecycle inside an information system : from their creation to their deletion (or archiving) when they become obsolete. Data lifecycle management could be defined as the group of processes implemented in order to manage the enterprise's data from their definition to their retrieval ("technical" point of view). For instance, a typical question in DLM would be "When can you archive a particular datum ?".
