Choosing a tool in projects (Watson Studio)
With Watson Studio and its complimentary services, projects provide a range of tools for users with all levels of experience in preparing, analyzing, and modeling data, from beginner to expert. The right tool for you depends on the type of data you have, the tasks you plan to do, and the amount of automation you want.
To pick the right tool, consider these factors.
The type of data you have
- Tabular data in delimited files or relational data in remote data sources
- Image files
- Textual (unstructured) data in documents
The type of tasks you need to do
- Prepare data: cleanse, shape, visualize, organize, and validate data.
- Analyze data: identify patterns and relationships in data, and display insights.
- Build models: build, train, test, and deploy models to make predictions or optimize decisions.
How much automation you want
- Code editor tools: Use to write code in Python, R, or Scala, all also with Spark.
- Graphical builder tools: Use menus and drag-and-drop functionality on a builder to visually program.
- Automated builder tools: Use to configure automated tasks that require limited user input.
