Making the Dean's List is an honor, indeed, but it is just one semester's GPA - like making the National Honor Society "A" Honor Roll in Jr/High school. That really doesn't count for much outside of that semester - you can make the Dean's List several times and still not graduate with honors. Graduating with honors will be what you use on your resume to impress. Graduation with honors 'cumm laude' requirements can vary but in general: GPA for cumm laude (with honor) - 3.5 to 3.74; GPA for magna cumm laude (with great honor) - 3.75 to 3.99; GPA for summa cumm laude (with highest honor) - 4.0+. [the correct spelling for 'cumm' is with only one 'm' but our word censor program will not allow it - it thinks I'm trying to type a dirty word]
By data capa are you perhaps thinking of Delta Kappa? Different fraternities, and schools, have different requirements to pledge and actively participate in fraternity activities. You'll have to check with the fraternity to see what their requirements are.
Congrats on making the Dean's List for this semester. Keep up the good work and you'll graduate with honors!
