  • Cryptography: Hashing

    Hashing is a fundamental concept in cryptography that plays a critical role in securing data, ensuring integrity, and supporting various cryptographic protocols. A hash function takes an input (or “message”) and returns a fixed-size string, which typically appears random. The key characteristic of a hash function is that it is a one-way function, meaning that…

  • Read duplicate

    In the context of data management, software development, and database systems, the term “read duplicate” often refers to a situation where the same data is retrieved multiple times within the same query or process. This can lead to inefficiencies, incorrect results, or unnecessary load on systems. Understanding the mechanics of read duplicates, their causes, and…

  • 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 Through Strategy

    The Write-Through Strategy is a caching technique used to ensure consistency between the cache and the primary data source. It is widely used in systems where data integrity and durability are critical, such as databases, distributed systems, and file storage. What is Write-Through Caching? In the Write-Through approach, every write operation is performed simultaneously on…

  • Hashing Algorithm: Infra Security POV

    In the realm of infrastructure security, hashing algorithms play a critical role in ensuring data integrity, confidentiality, and authentication. These cryptographic functions transform input data of any length into a fixed-size output, known as a hash. Hashing is used extensively in securing passwords, verifying the integrity of files, and enabling efficient data retrieval. In this…

  • Consistency: ACID Compliance

    In database systems, the ACID model (Atomicity, Consistency, Isolation, Durability) provides a foundational framework for ensuring robust and reliable transactions. Among these principles, consistency ensures that a database transitions from one valid state to another, maintaining adherence to all predefined rules, constraints, and data integrity protocols. It is a guarantee that, regardless of transaction outcomes,…
