Active Admin vs PostgreSQL: What are the differences?

<Write Introduction here>

1. Database Management System: Active Admin is a Ruby on Rails framework used for creating administrative interfaces, while PostgreSQL is an open-source object-relational database management system. Active Admin focuses on simplifying the process of creating administration interfaces for web applications, while PostgreSQL manages data storage and retrieval efficiently.

2. Purpose and Functionality: Active Admin is primarily used for creating intuitive interfaces for managing database content, whereas PostgreSQL is used as a robust backend system for storing and retrieving data. Active Admin streamlines the interface design process for developers, offering pre-built components and features, while PostgreSQL offers strong data integrity, concurrency control, and scalability for large applications.

3. Programming Language: Active Admin is written in Ruby, specifically designed to work with Ruby on Rails applications, while PostgreSQL is implemented in C language to ensure speed and reliability in data handling. Active Admin leverages Ruby's simplicity and flexibility for web development, while PostgreSQL's use of C allows for optimized database performance and efficiency.

4. Community Support and Contributions: Active Admin has a dedicated community of developers and contributors who actively maintain and update the framework, providing support and guidance to users, whereas PostgreSQL is supported by a large community of database professionals and open-source enthusiasts who contribute to its development and improvement continually.

5. Extensions and Plugins: Active Admin offers a wide range of extensions and plugins to enhance its functionality and customization options, allowing developers to tailor the administrative interface to specific project requirements, while PostgreSQL offers a variety of extensions and add-ons for optimizing database performance and expanding its features for different use cases.

6. Scalability and Performance: Active Admin is suitable for small to medium-sized projects, providing a user-friendly administrative interface without compromising performance, while PostgreSQL is designed for handling large volumes of data and complex queries, ensuring scalability, reliability, and high performance in demanding applications.

In Summary, Active Admin and PostgreSQL differ in their core functionalities, language of implementation, community support, extension options, and scalability and performance capabilities.
