MongoDB vs. Firebase: Where Not to Use Each Database?

When choosing a database for your project, it’s essential to understand the strengths of different options and their limitations.

where not to use firebase vs mongodb

Where Not to Use Firebase?

Although Firebase has several advantages, it’s essential to take into account the following situations when it might not be the ideal fit:

Connections among complex data

Firebase’s real-time database may not provide the necessary flexibility and querying capabilities if your project includes complex relationships between data items, such as many-to-many linkages or intricate hierarchical structures. Utilizing a relational database like MySQL or PostgreSQL could be preferable.

Advanced-Data Analytics

Firebase’s real-time database may offer more advanced querying and aggregation functionalities than you require if your application needs significant data analysis and reporting capabilities. Use data warehouses or specialized analytics solutions like Google BigQuery or Amazon Redshift in conjunction with Firebase to provide additional in-depth analytics capabilities.

Highly Transactional Applications

Firebase’s real-time nature is excellent for many scenarios. However, there might be better choices for highly transactional applications that demand strict consistency and complex transactional operations. Traditional SQL databases with ACID compliance, like Oracle or Microsoft SQL Server, might be more appropriate in such cases.

When Not to Use MongoDB?

Although MongoDB is well known for its scalability and flexibility, there are some instances where such qualities may not make it the best selection for a database:

Structured Data

A relational database system like MySQL or PostgreSQL may be more suitable if your project involves highly structured data with a set schema and well-established links between objects. MongoDB’s document model and flexibility shine in scenarios where the data structure is dynamic or evolving.

Strict ACID Compliance

If your application requires strict adherence to ACID (Atomicity, Consistency, Isolation, Durability) properties, MongoDB’s flexible document-oriented nature might not be the best fit. ACID compliance is crucial in financial systems or applications where data consistency is paramount.

Limited Hardware Resources

MongoDB’s distributed architecture and horizontal scalability are designed to handle large-scale deployments. If you have limited hardware resources or are working on a smaller project that doesn’t require massive scalability, a lighter-weight database like SQLite or PostgreSQL may be more appropriate.


Building a successful and robust application depends on selecting the correct database for your needs. When choosing the appropriate database for your app development project, you must carefully look after the process of updates in real time, data structure complexity, scalability needs, and pricing. By being informed about the advantages and disadvantages of MongoDB and Firebase, as well as their specific use cases, you can make decisions that align with your project’s objectives.
