ExtendedValidation

ExtendedValidation is a term often used in software development to describe a more thorough or comprehensive validation process than standard or basic validation. Standard validation typically checks for the presence of required fields, basic data type correctness (e.g., ensuring a number is entered where a number is expected), and adherence to simple format rules (e.g., a valid email address format). ExtendedValidation, in contrast, goes further by incorporating additional checks that are specific to the business logic or context of the application.

These extended checks can include a variety of scenarios. For instance, they might verify that a user's input is within a specific range of acceptable values, that a date falls within a valid period, or that a combination of fields meets certain interdependent criteria. ExtendedValidation can also involve checking against external data sources, such as a database or an API, to confirm the validity or uniqueness of the submitted information. For example, validating a product ID against an existing product catalog or checking if a user account already exists before allowing registration. The goal of ExtendedValidation is to catch a wider range of potential errors and ensure data integrity and application correctness at a deeper level, thereby improving the overall quality and reliability of the system.
