Database Access Layer Code Generation Directly from Use Case Scenarios

Abstract

Requirements definition is the first step in the life cycle of a software system. Requirements are formulated as paragraphs of text and appear ambiguous, so they cannot be translated directly into code. For this reason, they are treated as secondary artifacts for software developers. This paper presents a model-driven based approach where requirements are treated as first-class citizens, and can contribute to the final code. In this approach, requirements are formulated as use case models with their textual scenarios, using a precise requirements language called RSL, allowing an automatic transition to executable Java code. The structure of the generated code follows the Model-View-Presenter (MVP) architectural pattern. The work focuses on the Model layer code, which is responsible for the persistence and storage of data in a database system.
