Introduction of Client-Server Database Client-server architectures are common in many modern database systems. They form the basis for various applications, ranging from enterprise systems to web applications and mobile apps that rely on accessing and manipulating data stored in a centralized database. The client-server database architecture is a foundational model Read more…
Introduction of OODBMS Object-oriented databases(OODBMS) offer a way to model and manage complex data structures more naturally, aligning closely with object-oriented programming paradigms. Definition Object-oriented databases (OODBMS) are a type of database management system that stores data in the form of objects, encapsulating both data and methods (functions or procedures) Read more…
Introduction of DDBMS Distributed databases (DDBMS) play a crucial role in modern computing, having higher scalability, availability, and performance in handling large volumes of data across geographically dispersed locations. Definition Distributed databases store data across multiple physical or logical locations, providing improved scalability, fault tolerance, and performance by distributing data Read more…
Definition File organization refers to the way or techniques that give how the data is structured and stored within computer files or database files. Characteristics There are various file organization methods exist to store data in files, each designed to optimize data retrieval, storage efficiency, and ease of access. File Read more…
Introduction Definition Normalization is the process of organizing data properly and efficiently to minimize data redundancy and inconsistencies in the database by dividing the larger or complex or redundant database into simpler and smaller ones and also linking them using proper relationships as per requirements. Characteristics The process of Normalization occurs Read more…
Introduction Redundancy and anomalies are issues that can arise in the design and management of databases. They can lead to data inconsistencies, inefficiencies, and difficulties in maintaining data integrity. Proper database design, normalization, and the use of integrity constraints are essential practices to minimize these issues in a DBMS. Redundancy Read more…
Primary Keys A Primary key is a unique value in a column/field for a record in a table. It serves the data integrity and efficient data retrieval. Each value within the primary key column/field must be unique. No two/more records can have the same primary key value. Primary key columns Read more…
Introduction Relational Algebra is a theoretical foundation for the query languages(SQL) used in relational database management systems (RDBMS). Definition Relational algebra is a formal system used to manipulate relations (tables) in relational databases. Characteristics Relational algebra provides a foundation for expressing queries and transformations on relational databases. It’s a mathematical Read more…
