It allows users to create more flexible and complex workflows that can handle complex data processing requirements.ġ0. What is a data flow variable in KNIME?Ī) A variable that stores the output of a nodeī) A variable that stores the input of a nodeĬ) A placeholder for data values that can be used to pass data between nodesĭ) A variable that stores the name of a workflowĮxplanation: A data flow variable in KNIME is a placeholder for data values that can be used to pass data between nodes in a workflow. It allows users to create more flexible and dynamic workflows that can handle changing data inputs.ĩ. It allows users to group a set of nodes into a single node, making the workflow easier to manage and understand.ī) A type of node that performs a specific functionĮxplanation: A workflow variable in KNIME is a placeholder for data values that can be used throughout the workflow. They cannot type the connection name manually.Ī) A type of node that represents a sub-workflowī) A visualization tool for displaying metadataĮxplanation: A metanode in KNIME is a type of node that represents a sub-workflow. Which of the following is not a way to connect nodes in KNIME?Įxplanation: In KNIME, users can connect nodes by dragging and dropping them, copying and pasting them, or right-clicking and selecting the appropriate option. It consists of nodes and connections between them, which specify the data flow and processing steps.Ħ. Instead, users can combine various nodes to manipulate data, such as filtering, joining, and transforming nodes.Ī) A set of instructions for data analysisĬ) A graphical interface for data visualizationĮxplanation: A workflow in KNIME is a set of instructions that define how to process and analyze data. Which of the following is not a type of KNIME node?Įxplanation: Although data manipulation is a common function in KNIME workflows, it is not a specific type of node. Users can connect nodes to create a workflow that processes and analyzes data.Ĥ. However, it does not support complex data types.ī) A component that performs a specific functionĮxplanation: In KNIME, a node is a component that performs a specific function, such as data filtering, aggregation, transformation, or visualization. Which of the following is not a data type supported by KNIME?Įxplanation: KNIME supports various data types, including string, integer, floating-point, date/time, and Boolean. It provides a graphical interface for creating and executing data workflows, making it easier for users to analyze and visualize data.Ģ. A) A software application for data analysisĮxplanation: KNIME is an open-source software application used for data integration, processing, analysis, and reporting.
