query the vendor list, format each vendor information as a JSON object, and use additional queries to obtain a list of products from this vendor, and convert it to a JSON object array to attach to the vendor object. Other scenarios may use a link query to obtain a list of vendors and product information, which can be formatted as JSON objects using client code (additional queries may be generated if the Entity Framework is used). With the FOR JSON cl
