- Clean data based on data quality specs defined in Checks Studio and collect statistics
- Apply business logic defined in Rules Studio
- Perform data analysis operations - summary, correlation, etc.
- Score analytical models defined in Analytics Studio
Scheduling
Flows studio allows you to group transformation jobs into a flow and run them on schedule. In a flow you can:
- Group similar jobs
- Manage dependencies between jobs
- Setup a schedule - daily, weekly, monthly, specific date and time, etc.
- Monitor and debug previous runs
Glossary
Definitions studio allows you to create, modify and maintain a business glossary. In a glossary you can:
- Define entities, specify characteristics and relationship with other entities

- Perform basic data preparation - filter, append, merge, etc.
- Perform feature engineering
- Feature Extraction - word to vector, Inverse document frequency, etc.
- Feature Transformation - binarize, scale, normalize, etc.
- Feature Selection - slice vector, chi-sq select, etc.
- Develop clustering models - Kmeans, Guassian mixture model, lda, etc.
- Develop regression models - linear, decision tree, survival, isotonic
- Develop classification models - logistic regression, random forest, GBT, etc.
- Perform model tuning
- Build pipelines
Business Views
Business views studio allows you create a simpler logical view over complex data from various sources as business views.
Reports
Reports studio allows you to build reports over business views.
