Architecture Overview of the iWay Change Data Capture Solution for Informix

The following diagram illustrates the architecture of the iWay Change Data Capture (CDC) Solution for Informix.

  1. iWay Informix CDC Agent listens and reads the Informix Logical Log for INSERT, UPDATE, DELETE records using the Informix Change Data Capture (CDC) API.
  2. The iWay Informix CDC Agent processes the records, composes the corresponding ANSI SQL statements, and then writes them into an Output CDC Data File.
  3. iWay Log Event Listener listens to the Output CDC Data File and reads the SQL statements record by record.
  4. iWay Log Event Listener transforms every SQL statement and feeds the iWay CDC SQL Batch Agent.
  5. iWay CDC SQL Batch Agent applies SQL statements (INSERT, UPDATE, DELETE) to the target Oracle database tables.
