8.2 Views on Requirements 115 Definition of attributes by means of information models When employing tools for requirements management, defining the attribute structure of requirements is often not done by means of tables, but is model based, by means of information models. A model-based def- inition of an attribute scheme determines the attribute types as well as lim- itations in attribute values, similar to template-based definitions. In addi- tion, model-based attribute scheme definition allows for determining relations between attribute types of different attribute schemes. Advantages of model-based attributing Along with the advantages of table-based definition, model-based assignment of requirement attributes additionally allows consideration of requirement dependencies when selectively accessing the requirements. This aids in maintaining consistency in the attributes of the requirements. Furthermore, the information model of a model-based assignment of requirement attributes can serve as the foundation for the definition of an attribute structure to be used in a requirements management tool. (see section 9.3 ). Also, templates for the assignment of requirement attributes can be generated on the basis of the information model.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
