What are the top system design interview questions for Oracle interview?

System design interviews at Oracle often focus on building robust, scalable, and efficient systems, with an emphasis on database management, enterprise solutions, and cloud services. Here are some of the top system design interview questions that are commonly asked at Oracle:

Design a Distributed Database System

Candidates are expected to discuss the architecture required to build a distributed database system that ensures high availability, consistency, and fault tolerance. Key points include data partitioning, replication, consistency models (CAP theorem), and handling network partitions.

Design a Scalable Data Warehouse

This question tests the ability to design a system that can store and process large volumes of structured and unstructured data for analytics and reporting. Important considerations include ETL processes, data schema design, query optimization, and ensuring scalability and performance.

Design a Cloud Storage Service Like Oracle Cloud Infrastructure (OCI) Object Storage

Candidates need to explain how they would build a cloud storage service that handles large-scale data storage, provides high availability, and ensures data durability. Key aspects include data replication, load balancing, API design, and security measures.

Design an Enterprise Resource Planning (ERP) System

This question involves creating a system that integrates various business processes, including finance, HR, supply chain, and customer relationship management. Important considerations include modular design, data integration, user access control, and scalability.

Design a Multi-Tenant SaaS Application

Candidates should discuss how they would design a software-as-a-service application that supports multiple tenants, ensuring data isolation, security, and efficient resource utilization. Key points include tenant management, data partitioning, scalability, and customization options.

Design a Real-Time Analytics Platform

This question tests the ability to design a system that can ingest, process, and analyze data in real-time for business intelligence purposes. Important aspects include stream processing, data storage solutions, scalability, and providing real-time insights.

Design a High-Availability Backup and Recovery System

Candidates need to design a system that ensures data can be backed up and restored efficiently in case of failures. Key considerations include backup scheduling, data compression, encryption, and ensuring minimal downtime during recovery.

Design a Workflow Management System

This involves creating a system that manages and automates business workflows, ensuring tasks are completed efficiently and in the correct sequence. Important considerations include workflow modeling, task scheduling, user roles and permissions, and handling exceptions.

Design a Scalable API Gateway

Candidates should discuss the architecture for an API gateway that handles incoming API requests, performs routing, load balancing, and security checks. Key points include scalability, rate limiting, authentication, and monitoring.

Design a Customer Relationship Management (CRM) System

This question involves designing a system that helps businesses manage their interactions with current and potential customers. Important considerations include data storage, integration with other systems, user interface design, and providing analytics and insights.

These questions reflect Oracle’s emphasis on enterprise solutions, database management, and cloud services. Preparing for these questions involves understanding the technical aspects of system design, scalability challenges, and creating robust, user-centric solutions for enterprise applications.
