Kuidas kontrollib server edastatud andmete struktuuri õigsust?

Server checks the correctness of the transmitted data structure using validation, which may include:

• Data schemas (JSON Schema, XML Schema): the server compares the received data with a predefined schema to ensure all required fields are present and have the correct type.
• Validation at the business logic level: checking the validity of field values (e.g., number range, date format).
• Use of libraries and frameworks: many server platforms provide tools for automatic verification of data structure and types.

Example: if the server expects a JSON with fields "name" (string) and "age" (number), it will check that these fields exist and match the types before processing the request.
