Asked by Pravin Last Modified
Answer The MEAN stack traditionally consists of MongoDB, Express.js, Angular, and Node.js. MongoDB is a NoSQL database, which means it does not use the traditional SQL (Structured Query Language) for database queries. Instead, MongoDB uses a document-based model with JSON-like documents.
However, MEAN stack developers may still encounter SQL databases in certain scenarios or when working on projects that involve integrating with existing systems. For example:
Legacy Systems: In some cases, existing systems may use SQL databases, and a MEAN stack developer might need to interact with or migrate data from these systems.
Hybrid Solutions: Some projects may require the use of both SQL and NoSQL databases based on specific use cases. MEAN stack developers might work with SQL databases alongside MongoDB to meet the project requirements.
Job Requirements: Job positions for full-stack developers, including MEAN stack developers, may sometimes list SQL as a desirable skill. This is because a developer may need to work with various technologies and databases depending on the project or organization.
In summary, while MEAN stack developers primarily work with MongoDB as their default database, they may encounter SQL databases in certain situations. It's always beneficial for developers to have a broad understanding of different database technologies to adapt to various project requirements.
