# Enterprise Communication Interface (ECI)

## Introduction

This document describes the Interprocess Communication (IPC) based on Application Programming Interface in "C" (C-API) of the Engineering Database Agile e6 for the link with external CAX systems (CAD, CAM, DTP, PPS, CAX etc.).

| Important note for the implementation of links: To restrict the necessary implementation and maintenance effort when realizing a CAX-link, try to perform the desired link functions as often as possible directly in interactive mode with the comfortable Agile e6 system itself.
