BookExchange API

The design of the Web API follows CQRS pattern, that allows intercating with the main database (SQL Server) and ElasticSearch, for smart search of books.

BookExchange Application

Application layer of the web application, containing queries and commands for each entity, as well as the book recommendation service, based on the content-filtering algorithm.

BookExchange Domain

BookExchange Infrastructure

Contains the implementation of repositories for interacting with databases and dbContext.

SQL Server acts as a main database, which contains all of the data. ElasticSearch db contains only the information of books and allows to perform smart queries.
