Schema Validation
Schema validation is the process of verifying that structured data conforms to a defined schema or format specification.
“A type of static analysis based on a database schema.”

It ensures that data contains the required structure, fields, data types, and constraints before processing.
Structure verification: Data matches the defined schema.
Data quality: Prevents invalid or incomplete data from being processed.
Automation support: Often performed automatically during API or XML/JSON validation.
Real World Example
A regulated product team is preparing a release where Schema validation appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Schema validation as interchangeable with nearby ISTQB terms. That makes test scope blurry and can lead to weak evidence for the release decision.
The tester anchors the discussion in the official definition, asks where the concept appears in the product, and designs examples that show the difference between Schema validation and similar ideas.
The page becomes useful in practice because Schema validation is connected to a specific testing decision, not memorized as a detached definition.
