8. How Can SQL and NoSQL Work Together in University Back-End Development?

Using both SQL and NoSQL databases in university back-end development can be tricky. Here are some of the challenges:

1. Complexity in Integration:

   • Managing two different types of databases can make things more complicated.
   • Developers have to deal with different ways to connect, ask questions, and keep the data safe.

2. Data Consistency Issues:

   • SQL databases make sure data is very reliable thanks to something called ACID properties.
   • On the other hand, NoSQL focuses more on being available and can handle losing some data. This difference can cause problems with data accuracy.

3. Learning Curve:

   • Developers and database managers may need to learn skills for both types of databases, which makes training harder.

4. Performance Trade-offs:

   • Queries can get tricky, which might slow things down.
   • For example, getting data from both SQL and NoSQL at the same time can make it take longer to find what you need.

Possible Solutions:

• Microservices Architecture:
  By using a microservices approach, each service can be tailored for either SQL or NoSQL. This depends on what is needed for that specific task.

• Unified Data Access Layer:
  Building a shared API layer can simplify how developers work with both databases. This takes away some of the complicated parts.

• Cross-platform Training:
  Offering thorough training can help both staff and students learn what they need to know. This will create a more flexible development environment.
