The heart of DAE solution uses the modular design concept by breaking the solution down into smaller and independent modules. Each module performs a specific function and can be developed, tested, and replaced independently without affecting the operation of the entire system.

1. Flexible, Scalable Design
   • Modules can be added, removed, or modified without disrupting the entire system.
   • Allows for easier maintenance and upgrades.
2. Promotes Reusability and Standardization
   • Splitting complex systems into manageable and interchangeable parts.
   • Facilitates efficient development processes.
3. Incremental Implementation
   • Ability to implement modules individually.
   • Option to add additional modules in the future as needed.
