(Plugin for Indexing Multidimensional Data in PostgreSQL Using R-tree)
In commercial database platforms, the standard search over multiple attributes is provided by B+-tree (or it’s variants) with compound keys. On the other hand, such systems provide also multidimensional indexing, however, just for spatial purposes (such as GIS or CAD applications) and use special data types and querying syntax. Our solution allows to apply R-tree index (hence multi-dimensional indexing structure) in the same way as B+-tree with compound keys is applied. The solution is delivered as a plugin for PostgreSQL database.
