# Introduction {#introduction}

TYPO3 uses routes to generate [speaking URLs](https://docs.typo3.org/m/typo3/reference-coreapi/master/en-us/ApiOverview/Routing/AdvancedRoutingConfiguration.html) since version 9. Up to TYPO3 8.7 the extension *realurl* by Dmitry Dulepov was used.
*realurl* stored pathsegments of different fields in the database table *tx_realurl_uniqalias*.

## What does it do? {#what-it-does}

This extensions provides the route aspect type **CcPersistedPatternMapper**, which maps database fields such as news title to the path segment and persists it to the database. So it is possible to convert special chars, umlauts etc.
