QualiBD: A Tool for Modelling Quality Requirements for Big Data Applications

The development of Big Data applications is not well-explored, to our knowledge. Embracing Big Data in system building, questions arise as to how to elicit, specify, analyse, model, and document Big Data quality requirements. In our ongoing research, we explore a requirements modelling language for Big Data software applications. In this paper, we introduce QualiBD, a modelling tool that implements the proposed goal-oriented requirements language that facilitates the modelling of Big Data quality requirements.
