Liiketoimintakerros

Liiketoimintakerros is a Finnish term that translates to "business layer" in English. It refers to a conceptual or architectural division within a software system or enterprise architecture. The primary function of the liiketoimintakerros is to encapsulate and manage the core business logic and rules of an organization. This layer acts as an intermediary between the user interface (presentation layer) and the data storage (data layer).

In essence, the liiketoimintakerros defines how business operations are performed. It contains the processes, workflows, and decision-making logic that are unique to a particular business. For example, in an e-commerce system, the liiketoimintakerros would handle tasks such as order processing, inventory management, payment validation, and customer account management. It ensures that these operations are carried out according to the business's specific requirements and policies.

By separating business logic from other system components, the liiketoimintakerros promotes modularity, maintainability, and reusability. Changes to business rules can be made within this layer without significantly impacting the user interface or the underlying data structures. This architectural pattern also facilitates easier integration with other systems and services, as the business layer provides a well-defined interface for external interactions. The concept aligns with layered architecture principles common in software development and enterprise design.
