Other access methods

The way that the generic B-tree secondary-access method orders data is useful for one-dimensional data. When your data type is not one dimensional, you might need to use some other access method.

For information about the R-tree access method, refer to the Informix® R-Tree Index User's Guide. For more information about the secondary-access methods that DataBlade® modules provide, check the user guide for your DataBlade® module.
