DMSS

A Domain Specific Language (DSL) designed to define and execute business processes, automatically generating production ready Java and SQL code from high level specifications.

The Challenge

Business process automation often requires translating informal workflow descriptions into working software. This translation step is error-prone, slow, and creates a gap between what domain experts describe and what engineers implement.

The Solution

DMSS bridges this gap by providing a custom language that domain experts can use to formally describe their processes. The DSL compiler then generates:

• Java code: Service layer implementations following clean architecture patterns
• SQL schemas: Database definitions matching the process data model
• Process orchestration: Workflow execution logic derived from the DSL specifications

Technical Implementation

The DSL was built using language engineering techniques including:

• Grammar definition: Formal grammar specifying the syntax of business process descriptions
• Parser and AST: Transforming textual specifications into an Abstract Syntax Tree
• Code generation templates: Transpiling the AST into idiomatic Java and SQL

The result is a system where modifying a business process means editing a declarative specification file, not refactoring application code.

Academic Context

This project was developed as part of my Software Engineering degree at the Universidad de Extremadura, exploring the intersection of model-driven development and domain-specific languages.
