Excel can be used to design a database by organizing data into tables, with each table representing a different aspect of the data being tracked. For example, a basic database layout for a gradebook for a graduating class’s overall GPA might include a table for student information, a table for course information, and a table for grades. The student information table might include columns for student name, student ID, and contact information. The course information table might include columns for course name, course ID, and instructor name. The grades table might include columns for student ID, course ID, and grade.
If a business existed that used students’ information to propose specific colleges for them, several columns from the original spreadsheet would be kept, such as student name, student ID, and GPA. In addition, several new columns would be added to the database to support the business’s needs. For example, a column for intended major might be added, to help the business suggest colleges that have strong programs in that area. Another column for geographic location might be added, to help the business suggest colleges that are located in areas that the student is interested in. A third column for extracurricular activities might be added, to help the business suggest colleges that have strong programs in those areas. Finally, a column for SAT or ACT scores might be added, to help the business suggest colleges that have appropriate admissions standards.
Together, these columns would help the business’s database function by providing more detailed information about each student, allowing the business to make more informed recommendations about which colleges would be the best fit for each student. By organizing this information into a database, the business could quickly and easily search for relevant data, compare different students’ profiles, and track the effectiveness of their recommendations over time.
