  I try to explain the purpose of each project briefly.

It is responsible for calculation and performing business logic of the application. In this solution it convert a decimal number ( cheque amount ) to its equivalent presentation.This layer is used by API layer for data manipulation

It provides common functionalities to other projects. In this solution, database connection string to other project is provided by this project.

This project is the data access layer of the solution and talks to database directly. It is responsible for simple CRUD functionalities and provides data functionalities to API layer only.

This is the database project of the solution. It contains SQL table and stored procedures.

This project holds the data model of the application. Entities such as cheques request and response are in this project

This is the API layer of the solution which exposes basic functionalities through REST APIs. other clients can subscribe to its endpoints and send or receive data. It is implemented using ASP.Net Web API

This is the presentation layer of the application implemented in ASP.Net MVC and bootstrap.This layer consumes the API layer as a client

This is the test project of the solution contains Integration test for API, Business and Data components

• Dependency injection through constructor and IOC container. I used SimpleInjector for IOC container
• Separation of concerns through multi-layers application patterns
• Singleton design pattern for memory intensive resources like HttpClient
• Programming against Interface
• Single Responsibility through various projects and separate classes which promotes extend-ability
• ORM for performing CRUD with database . I used Dapper for the ORM
• Integration Testing. I used Nunit and NSubsitute for testing framework
