Sequelize features and specs

• ORM Abstraction
  Sequelize provides a robust Object-Relational Mapping (ORM) layer, allowing developers to interact with the database using JavaScript objects instead of raw SQL queries. This abstraction simplifies database operations and improves code readability.
• Cross-database compatibility
  Sequelize supports multiple SQL dialects including PostgreSQL, MySQL, MariaDB, SQLite, and Microsoft SQL Server. This flexibility makes it easier to switch between different database systems without major changes to the application code.
• Query Builder
  Sequelize offers a powerful query builder that allows complex queries to be written in a more intuitive and maintainable way compared to raw SQL. This includes support for nested queries, eager loading, and more.
• Active Community and Ecosystem
  Sequelize has a large and active community, providing a wealth of tutorials, plugins, and ongoing support. This makes it easier to find solutions to common problems and to extend the functionality of Sequelize.
• Migrations and Seeder Support
  Sequelize provides built-in tools for creating database migrations and seeders, making it easier to manage and version the database schema over time.
• Validation and Constraints
  Sequelize offers built-in validation and constraint features that allow developers to define rules and conditions that data must meet before being inserted or updated in the database. This helps maintain data integrity and consistency.

Possible disadvantages of Sequelize

• Learning Curve
  While Sequelize simplifies many database operations, it has a steep learning curve for beginners. Understanding all the features and properly implementing them can take time and effort.
• Performance Overhead
  The abstraction layer that Sequelize provides can sometimes introduce performance overhead compared to raw SQL queries. For highly performance-sensitive applications, this might be a concern.
• Complexity in Complex Queries
  Although Sequelize's query builder is powerful, creating very complex queries can become cumbersome and may require significant effort to optimize. Sometimes raw SQL might be more straightforward for these cases.
• Limited NoSQL Support
  Sequelize is designed primarily for SQL databases, and its support for NoSQL databases is limited. If your application requires interaction with NoSQL databases, you may need to look for other ORM solutions.
• Documentation Gaps
  While the official documentation is comprehensive, there can be gaps or lack of clarity in some areas, especially for advanced features. Users may need to rely on community support and external tutorials to fill in these gaps.
• Handling Large Data Models
  For applications with very large and complex data models, maintaining Sequelize models and associations can become challenging and error-prone. This might necessitate additional tooling or practices to manage effectively.
