10layer

10layer is a term that has emerged in discussions related to web development and application architecture, particularly concerning the organization and layering of software components. While not a formally standardized or universally adopted architectural pattern, it generally refers to a conceptual model that divides an application into ten distinct horizontal layers. Each layer is responsible for a specific set of functionalities and communicates with adjacent layers, typically only with the layer immediately above and below it.

The concept aims to promote modularity, separation of concerns, and maintainability by breaking down complex systems into smaller, manageable parts. The specific responsibilities assigned to each of the ten layers can vary depending on the context and the preferences of the development team. However, a common interpretation often includes layers such as presentation, user interface logic, application services, domain logic, data access, and infrastructure components.

The advantage of such a layered approach, regardless of the exact number of layers, lies in its ability to isolate changes. If a modification is needed in the data access layer, for instance, it should ideally not require changes in the presentation layer, assuming the interface between the layers remains consistent. This principle is a cornerstone of good software design and is fundamental to agile development methodologies. While a strict ten-layer model might be overly prescriptive for some projects, the underlying principle of structured layering remains a valuable concept in building robust and scalable applications.
