The task was to create a web application as a recordation of school marks. User can add a student in list, evaluate a student and also know an average grade per student or per subject.
It was needed to use Flask & SQLAlchemy.

There are three classes in my lab: Students, Subjects and Journal (description in model.py). We create a schema of database by the classes structure.

Class Students:
id - attribute of class (and table field)
name - attribute of class (and table field)
surname - attribute of class (and table field)
get_all - method of class to list all rows in table Students
get_st - method of class to find a student by name and surname
insert - method of class to add a student record into table

Class Subjects:
id - attribute of class (and table field)
subjname - attribute of class (and table field)
get_all - method of class to list all rows in table Subjects
get_d - method of class to find a student by subject name

Class Journal:
id - attribute of class (and table field)
student_id - related with Students.id
discipline_id - related with Subjects.id
grade - attribute of class (and table field)
date - attribute of class (and table field)
get_all - method of class to list all rows in table Journal
st_avg - method of class to calculate an average mark of a student
disc_avg - method of class to calculate an average mark of a discipline
insert - method of class to add a record in Journal table

To create a database with test data, run Create_SCHEMA.py

To run the application, run Server.py
