Normalized Systems (NS) theory describes how to design and develop evolvable systems. It is applied in practice to generate enterprise information systems using NS Expanders from models of NS Elements. As there are various well-established modelling languages, the possibility to (re-)use them to create NS applications is desired. This paper presents a mapping between the NS metamodel and the Ecore metamodel as a representant of essential structural modelling. The mapping is the basis of the transformation execution tool based on Eclipse Modeling Framework and NS Java libraries. Both the mapping and the tool are demonstrated in a concise case study but cover all essential Ecore constructs. During the work, several interesting similarities of the two metamodels were found and are described, e.g., its meta-circularity or ability to specify data types using references to Java classes. Still, there are significant differences between the metamodels that prevent some constructs from being mapped. The issues with information loss upon the transformation are mitigated by incorporating additional options that serve as key-value annotations. The results are ready to be used for any Ecore models to create an NS model that can be expanded into an NS application.

Innovative Solution

The increase of reliability and compliance of business processes is currently a major concern of organizations which simultaneously intend to achieve their organizational objectives and be compliant with external regulations. Thus, organizations are frequently looking for methods, tools and solutions which enable them to improve business compliance, and reduce the likelihood of situations that may jeopardize their operational performance and corporate image. This chapter aims to bring together a set of results and conclusions from a research project whose purpose was to conceptualize and validate an innovative solution which simultaneously monitors and audits organizational transactions executed in Enterprise Information Systems. A prototype was developed and deployed in a near-real environment. From the results, we conclude that the prototype offers Continuous Assurance services and is applicable to any organizational transaction, regardless of its type, dimension, business area or even its information system support technology. This independence is guaranteed by the abstraction level of an ontological model which is used to represent the organizational transaction we intend to monitor and audit. A case study enabled us to confirm the feasibility and effectiveness of the proposal in business compliance.

This chapter presents a case study of an overview of the efforts of Texas Instrument’s (TI’s) internal and external ERP implementation, with a focus on linking its ERP system in a global e-commerce setting. This linkage is especially important since it had been stated in TI’s strategic plan as an objective of this project to provide visibility of the ERP system to external constituents via Web linkages along with the objective of standardizing internal processes and important information technology systems to support market needs. Thus, its ERP system is central to managing its supply chain and B2B e-commerce linkages from both a customer and supplier perspective. Issues faced by TI are clearly outlined with future questions also posed in the final section.

Safety and pliability, for Enterprise Information Systems (EIS), are fundamental aspects in business. These data systems incorporate the human users with the required behaviours, experiences, and capabilities. In that regard, they have to be pliable, usable and secure. Pliability necessitates the capability to adapt and prepare to handle the perpetuating transforming conditions, which are meant to restore the complete capacity of the incidents and the attack in EIS. In this research is purpose to discuss pliability, security and the Information Systems (IS) problems in the EIS. The problem necessitates the consideration of ergonomics of efficiency, effectiveness and interactions of obligation realization, user trust and user satisfaction, including human emotions when utilizing the secured services. This paper also proposes a technique centred on the socio-technical paradigm and systems meant to model the kinds of interplays between usability, security and pliability. We provide a discussion, based on case study, meant to display the projected approach and focussing on the user-experience centred on the design structures.
