Quicklinks and Translations
Introduction

This page documents the databases tables used in OpenSimulator.

Tables are split up into Common, Services and Simulator.

On a grid, the grid services will contain the Services and Common tables, whilst each simulator instance will access the Simulator tables.

A standalone will contain Common, Services and Simulator tables, with the exception of the regions table, which is not currently persisted for standalones.

SQLite is generally not considered appropriate for this use case and will not be covered here; however the table structures are very similar and most of what is here will be useful in that context as well.

Note that some of these tables may be relics, some may be planned for future use, and some may see heavy use but have columns which are relics, not yet properly updated or not yet used at all.

Code

There is a common package for database code, OpenSim.Data and each database has its own package (e.g. OpenSim.Data.MySQL).

Each database package has to supply implementations for the interfaces in OpenSim.Data. For instance, IAssetData is the asset interface, used by OpenSimulator to store and retrieve asset data.

Organization

OpenSimulator 0.9.x onwards

Robust
  • Avatars - Persistence of the visual appearance of avatars between logins and attached objects
  • Friends - A list of an avatars friends, friendship requests, and permissions granted to friends
  • GridUser - Information about a user in this particular grid, for everyone who uses the grid, local and foreign. This includes their home region, last region, online status and last login/logout. This is distinct from auth information
  • Presence - Region and session information for currently logged in users. Used for IM routing amongst other things.
  • UserAccounts - User account information, such as name, user level and e-mail. Just local accounts.
  • assets - Grid assets including such things as textures and sounds
  • auth - User authentication information
  • inventoryfolders - Inventory folder-related details except for the contents
  • inventoryitems - points back to inventoryfolders
  • inventoryitems - All inventory item details (including folder associations) except contents - contents are referenced in the assets table
  • regions - Regions known to the grid
  • tokens - unused
Simulator
  • land - Parcel Properties
