1. MVC Validations Ensuring Data Integrity and User Input Validation Asaf Guttman January 30, 2025

2. Introduction to MVC Validations MVC Architecture is: Model: Manages data and business logic View: Represents the user interface Controller: Handles user input and interacts with the model and view

3. What is Validation? Definition: To insure integrity throughout the overall program. Purpose: Ensures data integrity and prevents invalid data from being saved.

4. Types of Validations in MVC Client-Side Validation: Performed in the browser before data is sent to the server Server-Side Validation: Performed on the server after data is received Advantages and Disadvantages: Client-side: Improved user experience, immediate feedback, but can be bypassed Server-side: More secure, but slower feedback to the user

5. Data Annotations in MVC Common Data Annotations are: Required: Ensures the field is not empty StringLength : Sets a maximum length for a string Range: Defines a range for numeric values RegularExpression : Validates with a regular expression pattern

6. Client / Server Validations Advantages Client Advantages: Benefits of client-side validation is to prevent errors or invalid data going into the database or server. Server Advantages: Benefits of server-side validation provides added security and reliability.

7. Custom Validations Custom validation attributes in an MVC application is a powerful way to enforce specific validation rules that aren't covered by the default attributes

8. Displaying Validation Messages Error Message Handling : Displays validation error messages to the user. User Feedback: The importance of providing clear and concise feedback to users.

9. Conclusion Without Validations user interface and server would produce a large amount of errors and security related issues.
