1. The “Big Bang” Approach: All In at Once

This is the more traditional approach where you integrate all components at once and test them as a complete system.

Pros: How to Monitor PostgreSQL Databases

  • Simulates Real-World Conditions: It provides the most accurate representation of how the application will perform in production. It’s like conducting a dress rehearsal before the big show.
  • Early Detection of Major Issues: This method is effective in exposing fundamental problems with the system’s architecture or major dependencies. It’s like finding out if the foundation of your building is strong enough.

Cons:

  • Complex and Time-Consuming: This can be very challenging for large and complex applications as it requires a lot of time to set up the environment and execute the tests. It’s like trying to juggle a dozen balls at once.
  • Difficult to Isolate Issues: If you encounter a problem it can be tricky to pinpoint the exact component that’s causing it. It’s like trying to find a single faulty wire in a tangled mess.

2. The Incremental Approach: Building Block by Building Block

This method focuses on integrating and testing smaller components in a gradual step-by-step manner.
