ElephantSQL vs MongoDB: What are the differences?
Introduction
ElephantSQL and MongoDB are both popular databases used in web development. However, they differ in several key aspects. In this article, we will explore the differences between ElephantSQL and MongoDB.
-
Data Models: ElephantSQL follows the relational database model, which organizes data into tables with predefined schemas. On the other hand, MongoDB is a NoSQL database that uses a document-based model, where data is stored in flexible, schema-less documents in JSON-like format.
-
Scalability: ElephantSQL offers vertical scalability, meaning it allows you to increase the capacity of a single server by adding more resources such as CPU or RAM. MongoDB, on the other hand, offers horizontal scalability, allowing you to distribute data across multiple servers in a cluster, providing better performance and handling larger datasets.
-
Query Language: ElephantSQL utilizes SQL (Structured Query Language), the industry-standard language for managing relational databases. MongoDB uses its own query language called MongoDB Query Language (MQL), which is specifically designed for querying document-based databases. MQL offers more flexibility and power in querying complex nested structures.
-
Schema Flexibility: ElephantSQL requires a predefined schema, meaning you need to define the structure of your data before inserting it into a table. MongoDB, being schema-less, allows you to store data without a predefined schema, providing more flexibility, especially when dealing with evolving data models.
-
Data Integrity: ElephantSQL ensures data integrity through the use of constraints, such as primary keys and foreign keys, which enforce referential integrity and maintain data consistency. MongoDB does not offer built-in support for constraints, making it more suitable for scenarios where flexibility is prioritized over data integrity.
-
Community and Ecosystem: ElephantSQL has been around for a longer time and has a well-established community with a wide range of resources and support available. MongoDB, being a newer technology, also has a growing community and an extensive ecosystem, offering various tools, libraries, and frameworks.
In Summary, ElephantSQL is a relational database that follows a predefined schema model and offers vertical scalability, while MongoDB is a NoSQL database that uses a flexible document-based model, provides horizontal scalability, and offers a more flexible data model with no predefined schema.
