Read this lesson. Pay attention to the lifecycle (process) of data sets. Answer the questions in this lesson. 

Data lifecycle management (DLM) is the policy or process that governs organizational data use. You learned that data management is an administrative function and DLM is a process to manage and preserve that data. Remember, good DLM includes all the phases of the data lifecycle. This is essential to data-driven decisions and actions taken by organizations daily.

Sharing & Preserving Data

Preserving your data

What happens to your data when…

  • the software you use to render it changes or becomes obsolete?
  • the platform on which you manipulate it changes?
  • the hardware you created it on becomes obsolete?

Preservation means storing your data in a place where it will be:

  • Stored
  • Backed up
  • Discoverable
  • Accessible for the future (as much as possible)

Preservation means that it is a particular person's job to make every effort to make the data usable in the future.

Preservation = Long-term access

Some repositories ensure preservation of data over time
