+The Netdata Agent uses a time-series database (TSDB), named the [database engine

The default settings retain about two day's worth of metrics on a system collecting 2,000 metrics every second, but the

-For more information about the database engine, see our [database reference doc](/database/engine/README.md).
+If you have multiple nodes with the Netdata Agent installed, you can [stream
+metrics](/docs/metrics-storage-management/how-streaming-works.mdx) from any number of _child_ nodes to a _parent_ node
+and store metrics using a centralized time-series database. Streaming allows you to centralize your data, run Agents as
+headless collectors, replicate data, and more.
Storing metrics with the database engine is completely interoperable with [exporting to other time-series
databases](/docs/export/external-databases.md). With exporting, you can use the node's resources to surface metrics
when [viewing dashboards](/docs/visualize/interact-dashboards-charts.md), while also archiving metrics elsewhere for
further analysis, visualization, or correlation with other tools.
-If you don't want to always store metrics on the node that collects them or run ephemeral nodes without dedicated
-storage, you can use [streaming](/streaming/README.md). Streaming allows you to centralize your data, run Agents as
-headless collectors, replicate data, and more.
