What is RDBMS?
RDBMS stands for “Relational Database Management System.” A relational database management system (RDBMS) is a type of database software that allows users to create, maintain, and interact with a relational database. It is based on the relational model, which organizes data into one or more tables, each with a unique identifier. Each table consists of rows and columns, where each row represents a single record and each column represents a specific field of data within that record.
The RDBMS uses a set of well-defined rules and operations, known as relational algebra, to manage the data within the database. These operations include selecting, inserting, updating, and deleting data. The RDBMS also provides a Structured Query Language (SQL) interface, which allows users to interact with the database using SQL commands.
RDBMS also supports data integrity and consistency, through the use of constraints and keys, which ensure that the data is accurate and consistent across the entire database. The RDBMS also provides the capability of backup and recovery, which allows the user to retrieve data in case of errors or disasters.
Some of the popular RDBMS are MySQL, Oracle, Microsoft SQL Server, PostgreSQL, SQLite, MariaDB, IBM Db2, etc. These RDBMS are widely used in various applications such as e-commerce, financial management, and data analysis
