When querying a number, you can check whether the number can be obtained as the target type: Checking When a Number is parsed, it is stored in the DOM as one of the following types: Type RFC 4627 says the range of Number is specified by the parser implementation.Īs C++ provides several integer and floating point number types, the DOM tries to handle these with the widest possible range and good performance. Number can be an integer or a real number. JSON provides a single numerical type called Number. In the next tutorial, you'll buid the JSON data classification models and analyze the results.M.name.GetString(), kTypeNames)

The completed workflow looks like this: Description of Build Classification models to provide predictive analysis on the JSON data.Examine the JSON data using the JSON Query node.Specify the desirable attributes for query purposes.Once the data is in relational format, you can treat it as a normal relational data source and start analyzing and mining it immediately. The JSON Query node enables you to selectively query desirable attributes and project the result in relational format. In this lesson, you create a workflow that imports JSON data by using the JSON Query node. In additional, the current Data Source and Create Table nodes are enhanced to allow users to specify JSON data in the input data source.
