# Overview

The ENLYZE Manufacturing Data Platform represents your production through a set of **resources**: sites, machines, data sources, edge devices, production runs, and more. This section explains what each resource means, where it sits in the hierarchy, and where you find it in the ENLYZE App.

{% hint style="info" %}
**Platform and App:** You use ENLYZE through the **ENLYZE App**, the web interface. It has two areas, which you switch between via the menu in the bottom left:

* In the **Platform** area you set up and manage your data infrastructure organization-wide (sites, machines, data sources, edge devices, topology).
* In the **App** area you work with your data on a per-site basis: OEE, downtimes, analyses, Co-Pilot, and reports.
  {% endhint %}

## The hierarchy of your production

The resources build on one another. A company groups its sites, sites group machines, machines are supplied with data through data sources, and data sources deliver individual variables:

```
Company (organization)
└── Site
    └── Machine
        └── Data source
            └── Variable
```

The top level is the **company**. Each company is represented in ENLYZE as its own **organization**: all sites, machines, and data live within this one organization and are isolated from other companies. Users are assigned to the organization as well. You manage users and their roles under [User management](/en/administration/user-management.md).

This hierarchy model follows the industry standard ISA-95 (IEC 62264), which structures production facilities from the enterprise level down to the device level. ENLYZE uses the levels relevant to data acquisition.

## Resources at a glance

[**Production hierarchy**](/en/resources/production-hierarchy.md) describes what physically exists at the customer site:

* [**Sites**](/en/resources/production-hierarchy/sites.md): the top-level grouping of your production environment.
* [**Machines**](/en/resources/production-hierarchy/machines.md): the individual machines or lines for which KPIs like OEE are calculated.

[**Data infrastructure**](/en/resources/data-infrastructure.md) describes how ENLYZE acquires the data:

* [**Data sources**](/en/resources/data-infrastructure/data-sources.md): split into OT data sources such as controllers/PLCs, meters, and sensors that process data is read from, and IT data sources such as ERP, MES, and QMS systems that the production context is read from.
* [**Edge devices**](/en/resources/data-infrastructure/edge-devices.md): the devices that connect data sources and stream their data into the platform.

[**Production context**](/en/resources/production-context.md) describes what happens in production:

* [**Production runs**](/en/resources/production-context/production-runs.md): assign machine data to a product and time range.
* [**Products**](/en/resources/production-context/products.md): what is being manufactured.
* [**Downtimes**](/en/resources/production-context/downtimes.md): periods during which a machine is not producing.
* [**Setup sheets**](/en/resources/production-context/setup-sheets.md): the machine settings per product.

## Visualizing the relationships: the Topology View

The **Topology View** in the platform shows all resources and their relationships as an interactive graph. Sites, machines, edge devices, and data sources appear as nodes, their connections as edges.

At a glance you can see which data source is connected through which edge device, and to which machine at which site it belongs. You can search for nodes, filter by site, and spot connection errors directly in the graph. The Topology View is therefore well suited to reviewing your infrastructure and narrowing down connection problems.

The Topology View is also ideal for spotting problems in your infrastructure and identifying their root causes.
