Virtual-Index Interface Guide

These topics explain how to create a secondary access method with the Virtual-Index Interface (VII) to extend the built-in indexing schemes of HCL Informix® typically with a DataBlade module.

These topics are written for experienced C programmers who develop secondary access methods, as follows:
  • Partners and third-party programmers who have index requirements that the B-tree and R-tree indexes do not accommodate
  • Engineers who support HCL Informix customers, partners, and third-party developers

Before you develop an access method, you should be familiar with creating user-defined routines and programming with the DataBlade API.

For information about software compatibility, see the HCL Informix release notes.
