Domain-Driven Design (DDD)- Bridging the Gap between Business Requirements and Object-Oriented Modeling

Sandeep Kumar Jaiswal , Rohit Agrawal

Domain-Driven Design (DDD) has emerged as a powerful methodology for developing complex software systems by emphasizing a deep understanding of the business domain. By bridging the gap between business requirements and object-oriented modeling, DDD enables developers to create software solutions that are not only aligned with business needs but also maintainable, adaptable, and scalable. This research paper explores the principles, practices, and benefits of DDD, illustrating its effectiveness through case studies and examples.  We discuss how DDD fosters collaboration between domain experts and developers, encourages the creation of a ubiquitous language, and enables the modeling of complex domains through bounded contexts, aggregates, and domain events. Additionally, we examine the role of strategic design in DDD, including context mapping, bounded context, and the use of tactical patterns such as entities, value objects, and repositories. Through this comprehensive analysis, we demonstrate how DDD serves as a bridge between business requirements and object-oriented modeling, facilitating the development of software systems that are both technically sound and aligned with the needs of the business.
