Database migrations
in Entity Framework (EF) are a way of managing changes to the database schema over time in sync with the changes made in the application's data model (e.g., adding/removing fields, changing data types, etc.). Migrations allow developers to evolve the database schema in a structured and manageable way without losing data or causing inconsistency between the application's model and the actual database.

Lazy loading in Entity Framework (EF) is a technique used to delay the loading of related data until it is specifically needed. It allows entities and their related navigation properties to be loaded from the database only when they are accessed for the first time, rather than being eagerly loaded along with the parent entity. This can help improve performance by reducing the amount of data retrieved initially, especially when the related data is not always required.
