Read the first 7 Integration flashcards as text

  1. Which integration pattern uses a central hub to route messages between ERP modules, reducing point-to-point connections?

    Answer: Hub-and-spoke

    Hub-and-spoke routes all module communication through a central integration hub, minimizing the number of individual connections.

  2. When integrating ERP with a third-party CRM, what is the primary risk of using real-time synchronous calls?

    Answer: Increased latency and potential cascading failures

    Synchronous calls force the ERP to wait for the CRM response, so CRM slowness or failure directly stalls ERP transactions.

  3. What does 'idempotency' mean in the context of ERP integration message processing?

    Answer: Processing the same message multiple times yields the same result

    Idempotency ensures that duplicate or retried messages don't cause double-posting or data corruption in the ERP.

  4. An organization wants to integrate ERP procurement data with a supplier portal. Which approach best supports real-time inventory visibility without overloading the ERP database?

    Answer: Event-driven API with a change-data-capture feed

    Change-data-capture (CDC) streams only changed records in real time, giving suppliers current data without burdening the ERP with ad-hoc queries.

  5. What is the role of an integration middleware (ESB) in a large ERP landscape?

    Answer: Translate, route, and orchestrate messages between disparate systems

    An Enterprise Service Bus (ESB) acts as the integration layer handling message transformation, routing, and protocol mediation between systems.

  6. Which data format has become the dominant standard for modern ERP REST API integrations, replacing older XML-heavy approaches?

    Answer: JSON

    JSON is lightweight, human-readable, and natively supported by modern REST APIs, making it the de facto standard for ERP integrations today.

  7. During ERP integration testing, a 'golden record' test confirms what?

    Answer: All systems agree on the canonical, authoritative version of a data entity

    A golden record test validates that after synchronization, all integrated systems hold the same authoritative data for entities like customers or products.
