SchoolSystem

Project for the High Quality Code course at FMI

• Students have a first name, last name, grade and a collection of marks.
• Grades can be between 1 and 12.
• Teachers have a first name, last name and a subject that they teach. They also poses the mighty power to add marks to students. Poor kids...
• Marks have a subject and a value that can be between 2 and 6.

The program takes as input commands as strings. Each command consists of a name and a collection of parameters.

• CreateStudent [FirstName] [LastName] [Grade] - Creates a new student with the provided first name, last name and grade and prints out a success message that contains the full name, grade and the ID of the created student.
• CreateTeacher [FirstName] [LastName] [SubjectId] - Creates a new teacher with the provided first name, last name and subject and prints out a succes message that contains the full name, subject and the ID of the created teacher.
• RemoveStudent [StudentId] - Removes a student with the provided ID and prints out a success message.
• RemoveTeacher [TeacherId] - Removes a teacher with the provided ID and prints out a success message.
• StudentListMarks [StudentId] - Lists the marks of a student with the provided ID and prints out a list of marks in the format SUBJECT => MARKVALUE.
• TeacherAddMark [TeacherId] [StudentId] [Mark] - The teacher with the provided ID adds a mark to the student with the provided ID with the provided value.

Project structure

1. SchoolSystem.Data

Here is all the database related classes. Contains db context for entity framework (with an interface for abstraction), IRepository and IUnitOfWork with their implementations. Tests are located int SchoolSystem.Data.Tests

2. SchoolSystem.Models

This project contains the application models, which also are a representation of the database structure.

3. SchoolSystem.Factories

Contains interfaces for the factories, which create models. Because of Ninject's functionality (Ninject.Extensions.Factory) there are no implementation.

4. SchoolSystem.Providers

Interfaces for IReader and IWriter that allow easy switching of input and output streams. Implemented with ConsoleReaderWriterProvider (uses command prompt). Also ICommandParser which parses the input and creates a suitable ICommand implementation.

5. SchoolSystem.Services

Service layer for our application - contains ITeacherService and IStudentService interfaces for abstraction over the operations with different models. Also service implementations are there Service unit tests are located in the SchoolSystem.Services.Tests project

6. SchoolSystem.Commands

Project contains the abstraction ICommand interface and the ICommandFactory. Also implementations for different commands are contained in this project. All command implementations are unit tested in the SchoolSystem.Commands.Tests project

7. SchoolSystem.Core

This project contains the IEngine abstraction with the specific Engine implementation for running the application. It gets input from the injected IReader, parses and runs the command, and prints the output to the IWriter

8. SchoolSystem.CLI

Console interface for the application. Contains a DbContextFactory for entity framework migrations (only used in development). SchoolSystemModule which is the configuration for our inversion of control container. Program.cs is the main entry point of the application (composition root).
