ArangoDB vs Sequelize: What are the differences?

## Introduction
In this comparison, we will highlight the key differences between ArangoDB and Sequelize, two popular databases used in web development.

## 1. Data Modeling:
**ArangoDB:** ArangoDB is a multi-model database that supports graphs, key/value, and document data models natively.
**Sequelize:** Sequelize is an ORM (Object-Relational Mapping) for Node.js that primarily deals with relational databases like MySQL, PostgreSQL, etc.

## 2. Query Language:
**ArangoDB:** ArangoDB uses AQL (ArangoDB Query Language) for queries, which is similar to SQL but tailored for multi-model capabilities.
**Sequelize:** Sequelize uses SQL for querying data from relational databases, allowing developers to write raw SQL queries as needed.

## 3. Versatility:
**ArangoDB:** ArangoDB is designed for handling complex relationships between data through its graph capabilities.
**Sequelize:** Sequelize is more suitable for traditional relational data structures with predefined schemas.

## 4. Nature of Relationships:
**ArangoDB:** ArangoDB allows for easily defining and querying relationships between data entities, especially in the context of graph databases.
**Sequelize:** Sequelize primarily focuses on relationships established through foreign keys and associations in relational databases.

## 5. Scalability:
**ArangoDB:** ArangoDB is a scalable database that can handle large amounts of data and traffic with ease, making it suitable for high-demand applications.
**Sequelize:** Sequelize relies on the underlying relational database's scalability features, which may vary based on the chosen database engine.

## 6. Integration with Node.js:
**ArangoDB:** ArangoDB provides an official Node.js driver for seamless integration with Node.js applications.
**Sequelize:** Sequelize is specifically designed for use with Node.js, providing a robust ORM solution for Node.js developers.

In Summary, ArangoDB is more suited for handling complex data relationships, especially in a graph database context, while Sequelize is a reliable choice for traditional relational databases and integrates seamlessly with Node.js applications.
