Unit Of Work Pattern
The Unit of Work pattern is a design pattern in software development that maintains a list of objects affected by a business transaction and coordinates the writing out of changes and the resolution of concurrency problems. It acts as a central coordinator for tracking changes to objects and ensuring that all changes are persisted together as a single atomic transaction, typically in the context of data access layers and object-relational mapping (ORM) frameworks.
Developers should use the Unit of Work pattern when building applications that require consistent and transactional data persistence, such as in enterprise systems, web applications with complex business logic, or when using ORMs like Entity Framework or Hibernate. It simplifies data management by grouping multiple operations into a single transaction, ensuring data integrity, reducing database round-trips, and handling concurrency issues effectively.
