Sigmasoft Infotech Interview Questions and Answers

OOPS (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.

• OOPS focuses on creating objects that interact with each other to solve problems

• Key principles include encapsulation, inheritance, polymorphism, and abstraction

• Encapsulation involves bundling data and methods that operate on the data into a single unit

• Inheritance allows a class to inherit proper...read more

Data partitioning enhances performance and scalability in distributed computing by dividing data into manageable segments.

• Improves parallel processing: Each partition can be processed simultaneously by different nodes, speeding up data processing.

• Reduces data transfer: Only relevant partitions are sent to nodes, minimizing network traffic and latency.

• Enhances load balancing: Distributing data evenly across nodes preven...read more

Snowflake architecture separates storage and compute for scalable data processing and analytics.

• Multi-cluster architecture allows for concurrent processing without performance degradation.

• Storage is decoupled from compute, enabling independent scaling based on workload demands.

• Data is stored in a centralized repository, accessible by multiple compute clusters.

• Supports structured and semi-structured data formats like JS...read more

Designing a real-time data pipeline involves data ingestion, processing, storage, and visualization for immediate insights.

• Identify data sources: Use tools like Apache Kafka for streaming data from IoT devices or web applications.

• Data ingestion: Implement real-time data ingestion using tools like Apache Flink or Spark Streaming.

• Data processing: Use stream processing frameworks to transform and enrich data in real-time.
