The data lifecycle

Data management comprises all disciplines related to handling data as a valuable resource, it is the practice of managing an organization’s data so it can be analyzed for decision making.[1]

Concept

The concept of data management arose in the 1980s as technology moved from sequential processing [2] (first punched cards, then magnetic tape) to random access storage.

Since it was now possible to store a discrete fact and quickly access it using random access disk technology, those suggesting that data management was more important than business process management used arguments such as "a customer's home address is stored in 75 (or some other large number) places in our computer systems." However, during this period, random access processing was not competitively fast, so those suggesting "process management" was more important than "data management" used batch processing time as their primary argument.

As application software evolved into real-time, interactive usage, it became obvious that both management processes were important. If the data was not well defined, the data would be mis-used in applications. If the process wasn't well defined, it was impossible to meet user needs.

Topics

Topics in data management include:

  1. Data governance
  2. Data architecture
  3. Data modeling and design
  4. Database and storage management
  5. Data security
  6. Reference and master data
  7. Data Integration and inter-operability
    • Data movement (ETL, ELT)
    • Data interoperability
  8. Documents and content
  9. Data warehousing and business intelligence and Analytics
  10. Metadata
  11. Data quality

Usage

In modern management usage, the term data is increasingly replaced by information or even knowledge in a non-technical context. Thus data management has become information management or knowledge management. This trend obscures the raw data processing and renders interpretation implicit. The distinction between data and derived value is illustrated by the information ladder. However, data has staged a comeback with the popularisation of the term big data, which refers to the collection and analyses of massive sets of data.

Several organisations have established data management centers (DMC) for their operations.[3]
