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.

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.
