How can a string field have choices?

[othomas1]

Hello community, im having some trouble understanding how a string type field, can have choices. The two screenshots are from the cmdb_ci_appl table, a field labeled "Business criticality", i see that the base table is cmdb_ci but how can i replicate this if i need to create a similar field on a new table?
