Data lifecycle management and information lifecycle management are related concepts but they are not the same.
Data lifecycle management (DLM) is the process of managing the entire lifecycle of data, from creation to deletion, while ensuring that it is properly managed and used throughout its life cycle. This includes everything from data acquisition, storage, use, maintenance, retention, and eventual deletion.
Information lifecycle management (ILM) is a broader concept that encompasses data as well as other types of information such as documents, records, and knowledge. ILM is the process of managing the entire lifecycle of information, from creation to deletion or archiving, while ensuring that it is properly managed and used throughout its lifecycle.
While data lifecycle management is focused specifically on managing data, information lifecycle management is a more holistic approach to managing all types of information within an organization.
