CharModel

[[TOC]]

::: tip What is the CharModel? The CharModel is a model for characterization of the architecture of service-based systems. The CharModel is composed by four dimensions, inspired on the following microservices guidelines:

• Small and independent services
• Loose coupling
• Lightweight communication mechanisms
• Deployment independence
• Decentralized data management :::

Key Features

• Focused on the structural attributes size and coupling
• Based on static metrics, extracted from APIs and relationships
• Can be adopted in different stages of software life cycle (Design-time, Architecture mapping, Architectural evolution)
• Allows to analyze different components and perspectives, according to the interest scope

Dimensions

The CharModel dimensions are:

1. Size
2. Data Source Coupling
3. Synchronous Coupling
4. Asynchronous Coupling
