The document discusses various solutions and blueprints for integrating data between an Oracle relational database management system (RDBMS) and the Apache Kafka streaming platform. It begins with an introduction to microservices architecture and the need for integrating traditional and modern applications. It then outlines five blueprints for moving data from an Oracle RDBMS to Kafka, including polling database tables/views, change data capture, polling APIs, producing directly to Kafka, and using queues. Finally, it briefly discusses blueprints for moving data from Kafka to an Oracle RDBMS.

4. Introduction

5. Microservices / Modern Applications
• Highly decoupled
• Independently deployable
• Bounded Context/Aggregate (DDD)
• Responsible for their data
• Favour asynchronous, event-driven
interaction over synchronous
• Smart Endpoints and Dump Pipes
• Use Anti-Corruption Layer (ACL) if no
fit! M3M2

23. Oracle REST Data Services (ORDS)
• makes it easy to develop modern REST interfaces for relational data in the Oracle
Database and the Oracle Database 18c JSON Document Store
• ORDS maps HTTP(S) verbs (GET, POST, PUT, DELETE, etc.) to database transactions and
returns any results formatted using JSON
• Java middle tier application on WebLogic, Tomcat, Docker, Standalone (for
development)
https://www.oracle.com/database/technologies/appdev/rest.html

26. StreamSets Data Collector
• GUI-based, drag-and

• Both stream and batch
processing
• custom sources, sinks,
processors
• Monitoring and Error
