We have adhering to attributes around candidate.CAND_ID = Candidate identification.CAND LNAME = Last surname of candidateCAND_FNAME = an initial name of candidateCAND MI = center name the candidateCAND_DOB = day of bear of candidateCAND_QUA = Qualification the candidateCAND_MAJOR = significant subject of candidateCAND_EXP = variety of years of experience of candidate
