Possible disadvantages

  SQL Fiddle may exhibit performance limitations, particularly with complex queries or large datasets, as it operates on shared, limited infrastructure.
• Dependence on Internet Access
  As a web-based tool, SQL Fiddle requires an internet connection to access its features, which may not be suitable for offline work or conditions with limited connectivity.
• No Persistence
  Data and schemas on SQL Fiddle are not persistent, meaning they can be lost over time or due to maintenance, making it unreliable for long-term storage or ongoing project work.
• Limited Functionality
  SQL Fiddle may not support the full feature set or latest features of all database systems, potentially limiting its use for testing advanced or system-specific queries.

Possible disadvantages

• Lack of Community Interaction
  LearnJavaOnline lacks community features such as forums or discussion boards, which can limit opportunities for learners to engage with peers or get help.
• No Certification
