description: Salesforce Knowledge uses data categories to classify articles. Data categories are organized in category group. After creating category groups, admins decide which groups to use for Salesforce Knowledge articles. For example, if your org uses both the Answers and Salesforce Knowledge, you might want one category group to be used by the answers site and two other category groups for articles. Answers and articles can use the same category group. Authors can assign up to eight data categories from one category group to an article so that users searching for articles can find and filter by category. By default, all the category groups you create are assigned to Salesforce Knowledge
