Why Excessive Schemas Are Not Ideal:

Excessive schemas in a database can lead to several challenges that may negatively impact the system's performance, manageability, and scalability. Here’s why having too many schemas is generally not recommended:

• Increased Complexity: Difficult to manage, navigate, and maintain relationships across multiple schemas.
• Performance Issues: Queries across schemas can become slower; resource contention may occur.
• Security Challenges: Managing access control becomes cumbersome, increasing the risk of misconfigurations.
• Management Overhead: More work for routine tasks like migrations and updates; harder to enforce standards.
• Scalability Concerns: It is difficult to scale the database and adjust as needs grow.
• Maintenance of Code/Queries: Complex queries and dependencies increase as more schemas are added.

In Summary:

Multiple schemas can help organize data, but too many can cause more problems than they solve. It’s important to find a balance—use schemas for organizational value, but avoid excessive fragmentation that adds complexity..
