  The Spectrometer and Telescope for Imaging X-rays (STIX) on board Solar
Orbiter observes solar X-ray emission in the range of 4 &ndash; 150 keV and
produces spectra and images of solar flares over a wide range of flare
magnitudes. During nominal operation, STIX continuously generates data. A
constant data flow requires fully automated data-processing pipelines to
process and analyze the data, and a data platform to manage, visualize, and
distribute the data products to the scientific community. The STIX Data Center
has been built to fulfill these needs. In this paper, we outline its main
components to help the community better understand the tools and data it
provides. The STIX Data Center is operated at the University of Applied
Sciences and Arts Northwestern Switzerland (FHNW) and consists of automated
processing pipelines and a data platform. The pipelines process STIX telemetry
data, perform common analysis tasks, and generate data products at different
processing levels. They have been designed to operate fully automatically with
minimal human intervention. The data platform provides web-based user
interfaces and application programmable interfaces for searching and
downloading STIX data products. The STIX Data Center has been operating
successfully for more than two years. The platform facilitates instrument
operations and provides vital support to STIX data users.
