For NoSQL databases (MongoDB, Cassandra, Redis), discuss your experience with different NoSQL data models (document, key-value, graph) and when you would choose a NoSQL database over an SQL database. Highlight the advantages and disadvantages of each type of database. SQL databases are typically better for structured data and complex queries, while NoSQL databases are often preferred for large volumes of unstructured data, scalability, and high availability. Explain the criteria you use for choosing the right database for a specific project. This often depends on factors such as data structure, query complexity, scalability requirements, and consistency needs. Use practical examples from your projects to illustrate your points. For example, you could explain how you chose MongoDB for a project requiring high scalability and flexibility.
6. How do you implement REST APIs in your projects?
