tieredmodeller

Tieredmodeller is a modeling approach and accompanying tooling designed to create and manage tiered models, where a system is described as a set of layers or tiers with explicit interfaces and responsibilities. It emphasizes separation of concerns, modular composition, and scalable integration across layers. In typical use, tiers may include presentation, application logic, domain or business rules, data access, and external services. Components within a tier expose contracts to the adjacent tiers, enabling independent development, testing, and deployment.

Core concepts include tiers, components, contracts, data flow, and deployment configuration. Tier definitions capture behavioral and non-functional requirements, such as latency or reliability, at the tier level. The model is often described with a domain-specific language or configuration files and can be validated against constraints. The toolchain may support code generation, simulation, or documentation from the model, and can serialize models to common formats for interoperability.

Typical applications include software architecture design, system engineering, enterprise architecture planning, and education. Tieredmodeller supports workflows that begin with defining tiers, allocating components, specifying interfaces, and establishing data flows, followed by validation and artifact generation. The approach fosters traceability between requirements, architecture, and implementation, and can be used to compare alternative tiering strategies or to simulate performance characteristics across layers.
