Description: Entity Validation is the critical process of verifying the integrity and accuracy of data before it is stored in a system. This process ensures that entities, which can be user records, products, or any other type of information, meet certain criteria and defined rules. Validation can include format checks, verification of mandatory data existence, and validation of relationships between different entities. This process not only helps maintain data quality but also prevents errors that could affect the functioning of applications and systems. Entity Validation is essential in software development, especially in applications that handle large volumes of data, where accuracy is fundamental for decision-making and reporting. Additionally, it contributes to system security by preventing the entry of malicious data that could compromise system integrity. In summary, Entity Validation is a key component in data management, ensuring that the stored information is valid, consistent, and useful for users and applications that rely on it.
