DLM or ILM ?

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 ?". 

Information lifecycle management (or ILM for short) is generally defined as the management of data and their metadata from birth to destruction. By information we mean all data collections meeting user needs. This view takes place at the business level and according to the use of the information ("user" point of view). A typical question in ILM would be "Is this information still timely ?".

To know which strategy you should choose, you first have to understand what a datum is and how your company is going to use it.

You can indeed compare a datum to an atomic element that's part of an information which is necessary to a user. The datum is the raw material and the information is the use thereof.

As an example, let's take a customer file :

table client example

  • the column "addressLine1" contains a datum on a customer
  • the data contained in columns "addressLine1" + "city" + "postalCode" + "country" form an information on the customer = their home address

 

Life of a datum

Birth (or creation) --> exploitation (or evolution) --> retrieval (or deletion)
|
according to one's needs : extraction, fusion, migration...
 
Quality must be maintained all along the lifecycle !

 

The events happening during data's lifecycle are multiple and depend on the type of data and on the enterprise's needs. Each intervention during this cycle can represent a risk for the enterprise (data loss, failure to follow the legislation, data inconsistency...). A smart solution of DLM will naturally lower the "data risks".

Here is a presentation of the crucial steps of a datum's lifecycle, in our opinion, and whichever the origin or use of it :
