Managing student data programs are today a necessary tool for improving the efficiency, organization, transparency and quality of the educational process. The presented program is realized with JavaScript, HTML, CSS and Node.js technologies. It was designed taking into account two types of users, professors and administrators. Information provided is: student's grades, information about the professor's office and contact details, student's level of education (year of study and semester), ECTS credits, choice of majors for graduate studies, and the student's identification key. On the other hand, the functions provided to the professor are: entering grades, updating grades and changing personal data, such as password, office and contact. The administrator has the option of deleting students, enrolling students for multiple years of study, sorting students into ranking lists for graduate studies, registering new students and new professors, and enrolling students in graduate studies. The program automatically calculates the grade point average, the sum of ECTS points and the number of points for enrollment in graduate studies. In order to ensure correct operation, the program has been perfected with verification methods, such as validation and input restrictions, data verification and two-phase verification. These mechanisms help preserve data integrity, reduce errors, and ensure the reliability of records. This program is a prototype of an application intended for departmental departments, whose main role is the overall registration of students, a digital diary of grades and records of new professors in the system.
