ACTIVE RECORD Meaning and
Definition
-
Active Record is a design pattern used in software development, particularly in object-oriented programming, that facilitates the communication and interaction between an application and a database. It is a way of managing and representing data from a relational database in an object-oriented manner.
In the context of the Model-View-Controller (MVC) architectural pattern, the Active Record pattern is commonly used to model the domain logic and database operations of an application. It encapsulates the data access logic within the object itself, making it responsible for persisting itself to a database and performing CRUD (Create, Read, Update, Delete) operations.
The main principle of Active Record is that each database table is represented by a class, and each instance of that class represents a row in the table. These classes are known as "Active Record" classes. The Active Record class typically defines instance variables that correspond to the columns in the database table, and provides methods to interact with the database, such as saving, updating, and deleting records.
By implementing Active Record, developers can easily query, create, manipulate, and manage database records using intuitive and object-oriented code, eliminating the need to write complex SQL queries. This pattern promotes code reusability, maintainability, and ease of testing, making it a popular choice in many modern frameworks and libraries.

Etymology of ACTIVE RECORD
The word "Active Record" is derived from the combination of two separate terms: "Active" and "Record".
1. Active: In computer science and software development, "active" refers to something that is performing an action or actively involved in a process. It is often used to describe components that can manipulate or interact with data.
2. Record: In the context of databases and data management, a "record" refers to a collection of related data fields or information that is treated as a single unit. In the case of Active Record, it specifically represents a single instance of an object within an object-oriented programming paradigm.
The term "Active Record" was first introduced and popularized by the Ruby on Rails framework, which is a web development framework that follows the Model-View-Controller (MVC) architectural pattern.
