How the Data 360 data that Tableau Next analyzes is ingested and managed: data stream settings and edits, reusing and keeping data lake objects, packaging streams and data models in data kits, and how streaming transforms delete records.

- Certification: Salesforce Tableau Next Consultant
- Exam section: Data Setup
- Study guide: https://www.certifyforce.com/study-guide/tableau-next-consultant

**Official exam objective:**

> Understand basic Data 360 features capabilities, including data integration, management, preparation, and modeling.

## What the exam expects

- Place ingestion, DLOs and DMOs before a semantic model, and judge whether Tableau Next setup must wait for them.
- Configure and edit a data stream: renames, disabled fields, refresh modes, filters and file settings.
- Reuse an existing DLO for a new file stream, and delete a stream while keeping its DLO.
- Package data models and streams in a data kit, then create, deploy, update and uninstall it.
- Predict when a streaming data transform deletes a target record.

Key terms:
- **Data stream:** a connection plus the data it ingests into Data 360.
- **DLO (data lake object):** where ingested data is stored in its original form.
- **DMO (data model object):** the harmonized object DLO data is mapped to.
- **Data kit:** a wrapper around packageable Data 360 metadata for deployment.
- **Conditional deletion:** deleting a stream without implicitly deleting its DLO.
