NoSQL Database Technologies

As cloud computing continues to evolve, organizations are finding new ways to store the massive amounts of big data that are collected. Big data storage often require greater flexibility and scalability which can be provided by incorporating NoSQL technologies. NoSQL (Not Only SQL) is quickly becoming a popular approach to store large and unstructured data. This paper looks at the various classifications of NoSQL technologies as well as many of the notable characteristics of the technologies. The authors also describe some deficiencies of using NoSQL and give some explanation to why companies are adopting the technology. The paper concludes with suggestions for future research of NoSQL technologies and a content analysis of current articles in database management is provided in the appendix

Integrated management systems and workflow-based electronic document management: an empirical stud

Purpose: Many global organizations have aligned their strategy and operation via the ISO-based framework of integrated management system (IMS) that allows them to merge quality, environment, health and safety management systems. In such context, having a robust electronic document management system (EDMS) is essential, especially at global enterprises where a large amount of documents generated by processes flows through different work cultures. However, there is no "one-size-fits-all" design for EDMS because it depends on organizations' needs, size and resource allocation. This article discusses the interrelation between EDMS and IMS in order to suggest a best practice. Design/methodology/approach: This article methodologically based upon a qualitative, interpretivistic, longitudinal empirical study in a wind turbine factory. Findings and Originality/value: IMS improvement and effectiveness has been overlooking EDMS as a key factor in establishing appropriate technological support of the IMS processes. Rightful application of EDMS can further contribute to organizational learning, precision of documentation and cross-organisational collaboration. Research limitations/implications: Theorising on IMS needs a stronger perspective of the technological limitations and potentials of basing IMS on EDMS. Practical implications: IMS are complex systems involving a large number of administrative functions. EDMS provides a formal representation with automation potentials both heightening and securing document trustworthiness. Social implications: IMS has a tendency to stay with professionals, e.g. line managers and QA/QC/QMS professionals. The EDMS line of discussion suggests a broader inclusion. Originality/value: Researching IMS as a technological implementation is giving a better platform of aligning the IMS with other business processes and is bringing IMS closer to the operational activities within the enterprise.Peer Reviewe

Developing a sustainability KM strategy for HA planned works

Effective management of sustainability-related knowledge is central to the development of sustainable construction practices. Despite progress In other contexts, existing knowledge management efforts have been of limited value to contexts such as housing association planned works (cyclical replacement of housing components) due to an inability to reflect the specificities of these projects. This paper presents the development of a structured strategy to improve the capture, storage, retrieval and exchange of sustainability-related knowledge within housing association planned works. Knowledge mapping exercises based on semi-structured interviews were carried out within four different sized Scottish housing associations. Sustainability-related knowledge maps were developed for each activity focusing on managerial, economic, social, environmental aspects and overall flow of knowledge providing the basis for recommendations to improve the management of sustainability-related knowledge during planned works. The strategy promotes a structured approach providing housing associations with the opportunity to tailor the strategy to reflect their context and requirements. Practitioners from the case studies confirmed its usefulness especially for housing associations committed to sustainability but struggling to engage with high-level policy and strategies. One case study association has implemented the high-level principles to support its wider sustainability policy and is piloting a strategy for its planned works. </jats:p

Embracing Technological Advancements: Blockchain as a Driver for Innovation and Dynamic Capability Development [védés előtt]

This dissertation presents several novel contributions to the fields of technology management, entrepreneurship, organisational studies, and strategic management. The following sections outline the unique insights and new scientific findings generated through this research: ▪ This study provides a comprehensive examination of blockchain technology through the perspectives of organisation theories, including technology adoption theories and sensemaking theory, as well as two categories of Burrell and Morgan’s typology of sociological paradigms, the functionalist and interpretive paradigms. ▪ A new methodological approach is employed to examine the profiles of high-tech manufacturing enterprises within specific regional contexts, focusing on two Spanish regions. ▪ The application of novel-to-the-topic methodology, specifically two discrete choice models—the multinomial logit and mixed logit models—brings a new perspective to evaluating the likelihood of a firm’s innovation decisions on innovation novelty. ▪ This study explores the implementation of novel blockchain technology within small, early-stage businesses, shedding light on the challenges and opportunities associated with integrating blockchain into organisational processes. ▪ An actor-dependent view of external enablers has been incorporated into the external enabler theory within the context of blockchain-enabled emerging businesses. This theoretical advancement enriches the current framework by highlighting the influence of actors in shaping the adoption and dissemination of blockchain technology within organisations. ▪ The research integrates the theory of dynamic capabilities as a theoretical framework, providing a detailed analysis of the nature and function of dynamic capabilities in the establishment of new ventures. ▪ An in-depth analysis is offered on the advancement of sensing, seizing, and reconfiguring capabilities, supported by their microfoundations, within the context of early-stage companies, with particular attention given to the impact of blockchain technology. ▪ The conceptual model is constructed to demonstrate how the combination of external enablers, founders’ capabilities, and firm capabilities facilitated the formation and growth of new ventures. ▪ Two main propositions and three supporting sub-propositions are formulated that provide directions for future research. ▪ The conceptual framework is developed to illustrate how blockchain-enhanced dynamic capabilities reinforce the operations of emerging companies and sustain their competitiveness. ▪ Through the application of a case study approach, new empirical data on emerging Hungarian firms utilising blockchain was collected, addressing the deficiency in blockchain use cases. In summary, this dissertation makes significant theoretical and empirical contributions by offering novel perspectives, theoretical advancements, and empirical findings that enhance our understanding of the strategic implications of emerging technologies for organisational development and innovation

Electra : integrating constraints, condition-based dispatching, and features exclusion into the multiparadigm language Leda

Multiparadigm languages are languages that are designed to support more than one style of programming. Leda is a strongly-typed multiparadigm programming language that supports imperative, functional, object-oriented, and logic programming. The constraint programming paradigm is a declarative style of programming where the programmer is able to state relationships among some entities and expect the system to maintain the validity of these relationships throughout program execution. The system accomplishes this either by invoking user-defined fixes that impose rigid rules governing the evolution of the entities, or by finding suitable values to be assigned to the constrained entities without violating any active constraint. Constraints, due to their declarative semantics, are suitable for the direct mapping of the characteristics of a number of mechanisms including: consistency checks, constraint-directed search, and constraint-enforced reevaluation, among others. This makes constraint languages the most appropriate languages for the implementation of a large number of applications such as scheduling, planning, resource allocation, simulation, and graphical user interfaces. The semantics of constraints cannot be easily emulated by other constructs in the paradigms that are offered by the language Leda. However, the constraint paradigm does not provide any general control constructs. The lack of general control constructs impedes this paradigm's ability to naturally express a large number of problems. This dissertation presents the language Electra, which integrates the constraint paradigm into the language Leda by creating a unified construct that provides the ability to express the conventional semantics of constraints with some extensions. Due to the flexibility of this construct, the programmer is given the choice of either stating how a constraint is to be satisfied or delegating that task to the constraint-satisfier. The concept of providing the programmer with the ability to express system-maintained relations, which is the basic characteristic of constraints, provided a motivation for enhancing other paradigms with similar abilities. The functional paradigm is extended by adding to it the mechanism of condition-based dispatching which is similar to argument pattern-matching. The object-oriented paradigm is extended by allowing feature exclusion which is a form of inheritance exception. This dissertation claims that the integration provided by the language Electra will enable Leda programmers to reap the benefits of the paradigm of constraints while overcoming its limitations
