3. DataSphere Studio uses Linkis

        DataSphere Studio, referred to as DSS, is an open source part of WeBank’s big data platform Station-type data analysis and processing platform, the DSS interactive analysis module integrates Scriptis. Using DSS for interactive analysis is the same as Scriptis. In addition to providing the basic functions of Scriptis, DSS provides and integrates richer and more powerful data analysis functions, including Data services for data extraction, workflow for developing reports, visual analysis software Visualis, etc. Due to native support, DSS is currently the most integrated software with Linkis.
