Your School Maintains Information About Students In Several Interconnected Database

Your school maintains information about students in several interconnected database files. The student-contact file contains student contact information. The student-grades file contains student grade records, and the student-financial file contains financial records including tuition and student loans. Draw a diagram of the fields these three files might contain, which field is a primary key in each file, and which fields serve to relate one file to another. Use Figure 5.7 as a guide.
