About Data Annotations
Data annotation is one of the most famous methods of validation in the ASP.NET framework. It can be
placed within the domain model to dictate the model behavior while also simplifying debugging by
making validation rules transparent and easy to understand.
It is mainly used to convey information about a resource between resources. To give an example, it
can be a blog post about a news article or a comment or tag on a web page or image.
Data annotation is a structured model and format that enables annotations and can be utilized in
different software platforms.
In web development, data annotation refers to the annotation of web resources like web pages. With
data annotation, users can modify, add, or remove information from web resources without changing

About Fluent Validations
Fluent Validation is a free and powerful .NET library renowned for its quick and easy implementation of
validation rules. It offers a fluent syntax for defining validation rules, enabling the creation of separate
public classes, and easy user input validation, which helps maintain and prevent code bloat issues.
The library has various built-in validators and supports a variety of validation rules and features, such
as:
Customizable Validation Rules
Property-Level and Cross-Property Validation
Error Messages and Localization
Rule sets — group validation rules together
Asynchronous Validation
Custom Error Codes and Severity Level
Testing Support
Fluent Validation allows clean, maintainable, and better coding, which removes the requirement of data
annotations while creating a separate public class to test models.
