data management (DM)

Data management(DM) includes the capture of data, processing, administration, archiving and output. This includes the organization of data with search and query functions.

Other functional areas include data output, reorganization of data stocks or storage media, functions for recovering data and preventive procedures for restarting after system interruptions.

Modern data management takes into account the life cycle of data in all functions. During this time, data has different requirements for its protection, disk performance, storage media and management. These lifecycle characteristics are partly taken into account in Hierarchical Storage Management( HSM), and more comprehensively in Information Lifecycle Management( ILM).
