Introduction

TREX is based on a client/server architecture. The client component is integrated into the application that uses the TREX functions, and allows communication with the TREX servers. The server component processes the requests; it indexes and classifies documents and answers search queries. The server component comprises of the following individual servers:

• Web server with TREX extension
• RFC server
• Queue server
• Preprocessor
• Index server
• Name server

The figure below illustrates the individual components and the communication between components:
