System R is one of the first prototypes of a relational database management system (RDBMS), developed at IBM in the 1970s. It was an experimental project aimed at proving the feasibility and practicality of the relational model of data, which was proposed by E.F. Codd. System R laid the foundation for modern relational database systems … Read more
A project organization refers to the structured framework that defines the roles, responsibilities, and relationships among team members to achieve the objectives of a project. It ensures that tasks are allocated efficiently, communication flows smoothly, and resources are utilized effectively.

The INGRES (Interactive Graphics and Retrieval System) algorithm is a well-known database query processing algorithm developed as part of the INGRES (Interactive Graphics and Retrieval System) project. It was designed to handle relational database management system (RDBMS) queries, focusing on efficient query processing and optimization. The INGRES algorithm is mainly associated with query optimization, specifically … Read more
Query decomposition is an essential technique in distributed databases that breaks down complex queries into simpler subqueries that can be executed on different nodes of the database. In a distributed system, data is spread across multiple locations or nodes, and a single query can span multiple fragments of data. Query decomposition aims to optimize the … Read more
Data Security in Distributed Databases is a critical concern as these databases are spread across multiple servers and locations, often in different geographical regions. With data stored in multiple places, it becomes more vulnerable to security breaches, unauthorized access, and cyber-attacks. Ensuring data security in a distributed database is essential to maintain the integrity, confidentiality, … Read more
Horizontal Fragmentation refers to the practice of dividing a database into smaller, more manageable pieces called fragments. These fragments contain a subset of the data from the original database, based on certain criteria. The goal of horizontal fragmentation is to improve the performance of database queries by storing related data closer to where it’s needed … Read more
In today’s digital world, e-commerce websites handle millions of users, orders, and payments every day. As businesses grow and more people shop online, traditional databases struggle to keep up with the increasing demand. This is where distributed databases come in—they spread data across multiple servers instead of relying on just one. This helps e-commerce platforms … Read more

Model-Based Software Architecture (MBSA) is an approach to software development that uses models as the primary artifacts for designing, analyzing, and implementing software systems. These models serve as a blueprint for the system, enabling stakeholders to understand, communicate, and manage the system’s structure and behavior. MBSA can be viewed from two key perspectives: 1. Management … Read more
