How To Start Process of Data Classification?
First step is to evaluate and divide the various applications and data as follows:
- Structured data (statistically around 15% of data)
- Generally describes proprietary data which can be accessible only through application or application programming interfaces (API)
- Applications that produce structured data are usually database applications.
- This type of data usually brings complex procedures of data evaluation and migration between the storage tiers.
- To ensure adequate quality standards, the classification process has to be monitored by Subject Matter Experts.
- Unstructured data (all other data that cannot be categorized as structured around 85%).
- Generally describes data files that has no physical interconnectivity (e.g. documents, pictures, multimedia files, ... ).
- Relatively simple process of data classification is criteria assignment.
- Simple process of data migration between assigned segments of predefined storage tiers.

Famous quotes containing the words start, process and/or data:
“Stop usin’ your hands, Skip, and start usin’ your head.”
—Samuel Fuller (b. 1911)
“Yet I doubt not through the ages one increasing purpose runs,
And the thoughts of men are widened with the process of the suns.”
—Alfred Tennyson (1809–1892)
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
