Three reasons CK should utilize Data Categories when creating articles in Knowledge are:

Data Categories help organize the Knowledge base content displayed. Data categories are logical

groupings of articles that reflect your business needs and processes. You can create a data category

group and assign it to one or more article types, and then create data categories and subcategories

within that group. Data categories help you organize your articles by topic or criteria and make them

easier to find and browse by your users or customers.

Data Categories provide a way to secure access to the Knowledge base content. Data category

visibility is a setting that determines which data categories users can access based on their profiles or

permission sets. You can use data category visibility to control access to your articles based on their

data categories and ensure that only relevant and appropriate content is displayed to different users

or customers.

A Knowledge article can be tagged to more than one Data Category. A Knowledge article is a

document that provides information or answers to common questions or issues. A Knowledge article

can be tagged to one or more data categories within each data category group that is assigned to its

article type. This allows you to classify your articles by multiple criteria and make them searchable

and accessible by different users or customers.
