MBSqlE: Enabling SQL as Powerful Query Language for SysML v2 in Aviation

Abstract

Model-Based Systems Engineering (MBSE) has emerged as a promising paradigm to manage increasing engineering complexity of safety-critical systems. One significant challenge impeding the overall benefits of MBSE is the limited data accessibility of MBSE tools. This disconnect hinders both efficient collaboration and automation. In recognition of this challenge, the second version of the Systems Modeling Language (SysML) introduces a standardized Application Programming Interface (API). However, the API’s query model has some limitations. For instance, no direct graph traversal of the model is featured, leading to performance bottlenecks. To address this limitation, a data access based on the Structured Query Language (SQL) is proposed in this paper. The expressive yet mature syntax of SQL unlocks vast data extraction and model analysis possibilities. In addition, rigorously tested databases such as SQLite can serve as an intermediate model representation with potential for tool qualification in safety-critical domains.
