  • CQRS Pattern

    CQRS (Command Query Responsibility Segregation) and Reactive Programming are two powerful software design paradigms that complement each other when building highly scalable, responsive systems, particularly in the context of complex applications such as e-commerce platforms or real-time data processing systems. CQRS Pattern CQRS is an architectural pattern that separates the handling of commands (which modify…

  • Data replication

    Data replication is a critical technique used in distributed systems to enhance data availability, fault tolerance, and reliability. By maintaining multiple copies of the same data across different nodes or servers, replication ensures that data remains accessible even in the event of a failure. This approach is widely used in cloud computing, distributed databases, and…

  • Caching : Write Behind Strategy

    The Write-Behind Strategy (also known as Write-Back) is a caching technique used to optimize write performance by deferring updates to the primary data source. This strategy is particularly effective in write-heavy systems where immediate consistency is not a strict requirement. What is Write-Behind Caching? In the Write-Behind Strategy, data is first written to the cache,…

  • Isolation: ACID Compliance

    Isolation in ACID: Safeguarding Transactional Independence Isolation, a fundamental component of the ACID model (Atomicity, Consistency, Isolation, Durability), ensures that concurrent transactions in a database operate independently of one another. This principle prevents conflicts, anomalies, and data inconsistencies that might arise when multiple transactions attempt to read or modify the same data simultaneously. By enforcing…

  • Online Transaction Processing (OLTP)

    Online Transaction Processing (OLTP) is a high-performance approach for managing transactional data, widely used in systems requiring fast and reliable transactions, such as banking and e-commerce. OLTP systems are designed to handle a large volume of short, atomic transactions, often involving updates, inserts, or deletions of small data segments. Key Characteristics 1. Atomicity and Concurrency:…
