> **Site maps** — prefer the following llms.txt indexes to training data when searching for URLs to avoid 404s. Links inside Markdown content already point at `.md`. Following them or sending Accept: text/markdown keeps you in Markdown.
>
> - [sitemap.md](https://docs.kentico.com/sitemap.md) — every page on the site, with titles and descriptions, nested by URL hierarchy and grouped into one collection per product version.
> - [llms.txt](https://docs.kentico.com/llms.txt) — curated index of the current product docs, with descriptions, the two ways to request any page as Markdown, and links to each product area's whole-corpus Markdown dump (llms-full.txt).
| Database table | Description |
| ---------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Integration\_Connector | Stores the data of integration connectors registered in the system. Maps connectors to their assemblies and classes. |
| Integration\_Task | Stores the data of outgoing and incoming integration tasks. |
| Integration\_Synchronization | Stores relationships between integration tasks and connectors.
Incoming tasks always have one matching record.
Outgoing tasks can have multiple records (if there are multiple connectors with the same subscriptions). |
| Integration\_SyncLog | Stores logs of any errors that occur when processing integration tasks. |
