\libraries\nop.data
The Nop.data project contains a series of data access classes and methods to read and save data from a database or other data medium. It also helps to separate data access logic from your business objects. Nopcommerce uses the entity Framework (EF) Code-first method, which allows you to define entities in Nopcommerce code (all core entity classes are defined in Nop.core), and then let EF generate the database. That's why it's called Code-first. You can then query the object using LINQ, which itself transforms the query into an SQL statement and executes it in the database. Nopcommerce has a Cow B API that lets you fully customize the persistent mapping, and you can find code-first information here and here.
\libraries\nop.services
This project contains a series of core services, business logic, validation, and, if there is data, a method of computing data, the legendary Business Access Layer (BAL)
