# PARCserver Overview

This section provides a general overview of PARCserver, including its architecture and various functions. The basics of configuring and interacting with PARCserver applications are also introduced.

There are two types of PARCserver applications: those that require that a license for the dataPARC historian and those that are licensed individually or do not require a license.

The dataPARC historian is not required to utilize PARCview as a visualization tool. Also, several PARCserver applications may be used to process or monitor data from third-party historians. Many other dataPARC features are only accessible with a full PARCserver license including the dataPARC Historian.

| Fire Daemon | PARChistory |
| PARCaggregate | PARChistory Defrag |
| PARCalarm Server | PARChistory Average |
| PARCrollup Server | PARChistory Backfill |
| PARCtag Sync | PARChistory Import Server |
| PARCtask Server* | PARCcalc Config |

Some of the PARCserver applications have a corresponding client-side PARCview display or tool. For instance, [PARCtask Workflow Designer](/v1/docs/parctask-workflow-designer) is part of PARCview and [PARCtask Server](/v1/docs/parctask-server) executes the workflows set up in the Designer.
