a DBMS is uniformity in the units of data held in the database. Text meets none of those

DBMS requirements are rigid. DBMS requirements are nonnegotiable. You either arrange
data the way the DBMS wants you to or you don’t use a database.
And text is free form. No one tells the author of words or the speaker of words what to
say. The very essence of communication with language is the freedom to express one's
self as one desires. Every person expresses differently.

management system.
