Datasets vs. Analysis Models

A Dataset defines a usable SQL data boundary from one connection and selected schemas. It exposes table and field context and can carry Dataset-specific knowledge.

An Analysis Model organizes reusable semantic knowledge in versions for compatible data sources and schemas. Building a version creates a candidate knowledge version; switching the active version is a separate action. Binding a model can make eligible legacy Dataset knowledge read-only.

Neither object copies source database rows. Compatibility and binding do not guarantee that every question can be answered.
