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.
