# Data Source Support and Integration

JUNE5 is compatible with various data sources and can display their data centrally.

The following historian packages and interfaces are supported:

* [Dataforum acron](/june5-3.7/en/datenquellenunterstuetzung-und-einbindung/dataforum-acron.md)
* [Data Store](/june5-3.7/en/datenquellenunterstuetzung-und-einbindung/data-store.md)
* [OPC UA](/june5-3.7/en/datenquellenunterstuetzung-und-einbindung/opc-ua-ha.md)
* [OSISoft PI System](/june5-3.7/en/datenquellenunterstuetzung-und-einbindung/osisoft-pi-system.md)
* [GE Historian](/june5-3.7/en/datenquellenunterstuetzung-und-einbindung/ge-historian.md)
* [Siemens WinCC](/june5-3.7/en/datenquellenunterstuetzung-und-einbindung/siemens-wincc.md)
* [Microsoft OLE DB](/june5-3.7/en/datenquellenunterstuetzung-und-einbindung/microsoft-ole-db.md)
* [Honeywell Uniformance Process History Database (PHD)](/june5-3.7/en/datenquellenunterstuetzung-und-einbindung/honeywell-uniformance-process-history-database-phd.md)
* [Honeywell Experion Batch (HEB)](/june5-3.7/en/datenquellenunterstuetzung-und-einbindung/honeywell-experion-batch-heb.md)
* [JUNE5 Connector](/june5-3.7/en/datenquellenunterstuetzung-und-einbindung/june5-connector.md)
* [JUNE5 Batch Connector](/june5-3.7/en/datenquellenunterstuetzung-und-einbindung/june5-batch-connector.md)

The integration of data sources takes place in two sequential steps:

1. Create the endpoint
2. Configure data sources for the endpoint

Both configuration steps are performed in the web application. Depending on the data source type, measurements from the configured data source can optionally be imported individually or completely into the JUNE5 object model.

{% hint style="info" %}
Data is retrieved from a data source through a call in the web application. Data is only displayed in the web browser (e.g., in a line chart) once all data from the selected measurements has been successfully retrieved.

If a timeout is reported and the data is not displayed successfully, the following measures could lead to a **successful** query:

* Reduce the time range (from/to) for data retrieval
* Reduce the number of measurements to be queried
* Select a higher aggregation level (e.g., switching from process data to interval or daily data)
  {% endhint %}
