The Extract, Transform, Load (ETL) process design is difficult to perform because of the ambiguity of user requirements and the complexity of data integration and transformation. Current studies have explored the ontology-based approach to overcome these limitations by reconciling the semantics of user requirements within the ETL process design for easy generation of the ETL process specificati...

The requirements engineering phase of software development projects is characterised by the intensity and importance of communication activities. During this phase, the various stakeholders must be able to communicate their requirements to the analysts, and the analysts need to be able to communicate the specifications they generate back to the stakeholders for validation. This paper describes ...

The ISO 9241-210 standard provides a framework for human-centred design (HCD) activities comprising the four stages: context of use, specification of user and organisational requirements, design solutions, and evaluation against requirements. Other parts of the 9241 standard cover user interface design and usability. This paper uses the HCD framework to emphasise user experience (UX) design and...

Guidance for the development of the set of requirements, System Requirements Specification (SyRS), that will satisfy an expressed need is provided. Developing an SyRS includes the identification, organization, presentation, and modification of the requirements. Also addressed are the conditions for incorporating operational concepts, design constraints, and design configuration requirements int...

Complete, correct, and consistent requirements are essential to the development of large complex systems. The Requirements Elicitation, Capture and Analysis Process prototype tool (RECAP) provides automated assistance in identifying, capturing, analyzing, and using requirements. RECAP combines recent advances in natural language parsing, requirements specification, and knowledge-based rules to ...

The main aim of this chapter is to present and discuss a set of modeling and specification techniques, in what concerns their ontology and support in the requirements representation of computer-based systems. A systematic classification of meta-models, also called models of computation, is presented. This topic is highly relevant since it supports the definition of sound specification methodolo...

Multimedia presentations are difficult to handle in existence of user interactions and complex synchronization requirements. In this paper, we present a synchronization model which can handle both time-based and event-based actions. The model can cope with the VCR-type user interactions. We also give a simple rule-based synchronization specification language which does not complicate as user in...

Supervisory control theory enables control system designers to specify a model of an uncontrolled system in combination with associated control requirements, and subsequently to use a synthesis algorithm for automatic controller generation. The use of supervisory control synthesis can significantly reduce development time for supervisory controllers as a result of the unambiguous specification ...

Abstract In this part of our tutorial, we attempt to explain and cover several most important non‐imaging parameters that form the complementary base requirements list for an XR system specification. The specification is often treated with less attention, in many cases reason dissatisfactory performances. extensive experience, found critical when designing system, since have very high impact on...
