Behavior-driven development (BDD) is a process that was born out of Test-driven development (TDD).
BDD involves organizing tests such that their behavior is tested, rather than their implementation.
When designing these types of tests, think, “How can I describe, in sentence form, what this code does and what I should expect from it.”

The concept of Domain-Driven Design implies that the structure of a software solution is built around a certain business domain and matches its requirements.
DDD implies that you distinguish a certain bounded context, which is a set of entities tightly connected with each other but minimally connected with other entities in your system.
Bounded context is a good fit for a microservices architecture. It is much easier to build a microservice around a bounded context.
A repository is nothing but a class defined for an entity, with all the operations possible on that specific entity.
A Repository Pattern can be implemented in the following ways:
Non-generic: This type of implementation involves the use of one repository class for each entity. For example, if you have two entities Order and Customer, each entity will have its own repository.
Generic: A generic repository is the one that can be used for all the entities, in other words, it can be either used for Order or Customer or any other entity.
Unit of Work is referred to as a single transaction that involves multiple operations of insert/update/delete.
In other words, it means that for specific user action (say registration on a website), all the transactions like insert/update/delete and so on are done in one single transaction, rather than doing multiple database transactions.
