Based On Meta-demand Model Non-functional Set Of Requirements To Obtain Research And Analysis

Along with development of computer technology, the requirements for software of society are growing at extremely high rate, especially requirements for large-scale reliable software. At the same time economic and social development promote the research of requirement acquisition and analysis of large-scale reliable software. But the research of requirement acquisition and analysis are mostly based on small and medium information systems, which can not meet the needs of large reliable software research. Therefore, the paper introduces the concept of meta-requirement and meta-requirement set. At the same time, requirements are divided into functional requirement and non-functional requirement, this paper only researches the acquisition and analysis of meta-requirement and meta-requirement set about non-functional requirement.Firstly, the paper researches meta-requirement theory. This paper put forward to the concept of meta-requirement, basing the need of requirement analysis and management of complex information systems in modern society, and introduces the definition, elements, and characteristics of meta-requirement. On this basis, this paper put forward two methods to build meta-requirement, namely:(1) continuously subdivision from top to bottom. The requirement is subdivided continuously until it cannot be subdivided, that is, the minimum unit of requirements is found. (2) The grounded theory method. Starting from the bottom, analyze the data collected using grounded theory method. The analysis includes open coding, relational coding and core coding and so on. Then find out the meaning unit and conceptualize the meaning unit, finally, find out meta-requirement.Secondly, the paper researches non-functional meta-requirement set. The paper defines non-functional requirement and meta-requirement set, analyzes and researches the building processes of meta-requirement. Basing these theories, the paper proposes the method to building non-functional meta-requirement, and analyzes non-functional meta-requirement.Finally, at the end of the paper is case study. This paper indicated the feasibility to find meta-requirement and meta-requirement set. Using grounded theory, the paper analyzes the comment information of online banking, and finds out the non-functional meta-requirements and non-functional meta-requirement sets. Then the paper analyzes priority and correlation of these non-functional meta-requirement sets.
