R-tree secondary access method concepts

These topics provide a detailed discussion of the R-tree secondary access method and an in-depth discussion about how R-tree indexes work.

DataBlade module developers can use the Informix® DataBlade Developers Kit (DBDK) to develop the objects that form the DataBlade module that uses the R-tree access method. The Informix DataBlade Developers Kit (DBDK) automatically generates most of the SQL commands and some of the C code needed to create the objects. For purposes of clarity, however, this guide gives examples of the SQL commands and C code so that the process of creating the objects is easier to understand.

This guide uses the Shapes3 sample DataBlade module, described in Shapes3 sample DataBlade module, to illustrate how to use the R-tree access method and how to create DataBlade modules that implement the R-tree access method.
