+## Data freshness and update frequency
+Advanced hunting data can be categorized into two distinct types, each consolidated differently:
+
+- **Event or activity data**—populates tables about alerts, security events, system events, and routine assessments. Advanced hunting receives this data almost immediately after the sensors that collect them successfully transmit them to the corresponding cloud services. For example, you can start to query event data from healthy sensors on workstations or domain controllers almost immediately after they are available on Microsoft Defender ATP and Azure ATP.
+- **Entity data**—populates tables with consolidated information about users and devices. This data comes from both relatively static data sources, such as Active Directory entries, and dynamic sources, such as event logs. To provide fresh data, tables are updated every 15 minutes with any new information, adding rows that might not be fully populated. Every 24 hours, data is consolidated to insert a record that contains the latest, most comprehensive data set about each entity.

 The [advanced hunting](advanced-hunting-overview.md) schema is made up of multiple tables that provide either event information or information about devices and other entities. To effectively build queries that span multiple tables, you need to understand the tables and the columns in the advanced hunting schema.
 
-## Schema tables
+## Get schema information in the security center
+While constructing queries, use the built-in schema reference to quickly get the following information about each table in the schema:
+
+- **Tables description**—type of data contained in the table and the source of that data.
+- **Columns**—*all the columns in the table.
+- **Action types**—possible values in the `ActionType` column representing the event types supported by the table. This is provided only for tables that contain event information.
+- **Sample query**—example queries that feature how the table can be utilized.
+
+### Access the schema reference
+To quickly access the schema reference, select the **View reference** action next to the table name in the schema representation. You can also select **Schema reference** to search for a table.
