How does Fluent API provide more flexibility than Data Annotations when configuring relationships?

Fluent API in Entity Framework allows for defining complex relationships between entities using fluent syntax. This flexibility includes specifying custom naming conventions for foreign keys, mapping entities to different tables, defining cascading delete behavior, and more. Unlike Data Annotations, Fluent API provides a programmatic way to configure relationships, which can be more powerful and expressive, especially in scenarios involving complex data models or when you need to define relationships that cannot be expressed using attributes alone.
