The user, rather than the database itself, typically initiates data curation and maintains metadata. [8] According to the University of Illinois' Graduate School of Library and Information Science, "Data curation is the active and on-going management of data through its lifecycle of interest and usefulness to scholarship, science, and education; curation activities enable data discovery and ...
As an increasing portion of the world’s information output shifts from analog to digital form, preservation metadata is an essential component of most digital preservation strategies, including digital curation, data management, digital collections management and the preservation of digital information over the long-term.
For example, when an object is appraised (a sequential action that always occurs in the lifecycle of a digital object’s curation) if it adheres to or, more aptly, doesn’t adhere to certain institutional curation policies, it can be disposed of or reappraised—both of which are occasional actions in the lifecycle.
The Web is only one example of what might be considered the "data deluge". [2] For example, the Library of Congress currently amassed 170 billion tweets between 2006 and 2010 totaling 133.2 terabytes [62] [63] and each Tweet is composed of 50 fields of metadata. [64] The economic challenges of digital preservation are also great.
The term "digital curation" was first used in the e-science and biological science fields as a means of differentiating the additional suite of activities ordinarily employed by library and museum curators to add value to their collections and enable its reuse [12] [13] [14] from the smaller subtask of simply preserving the data, a significantly more concise archival task.

Records life-cycle in records management refers to the following stages of a records "life span": from its creation to its preservation (in an archives) or disposal. While various models of the records life-cycle exist, they all feature creation or receipt, use, and disposition.
Product life-cycle management (PLM) is the succession of strategies by business management as a product goes through its life-cycle. The conditions in which a product is sold (advertising, saturation) changes over time and must be managed as it moves through its succession of stages.
Examples include birth, death, medical/health, and educational records. e-Science , for example, is an area where ILM has become relevant. In 2004, the Storage Networking Industry Association , on behalf of the information technology (IT) and information storage industries, attempted to assign a new and broader definition to Information ...
