Practitioners’ view on command query responsibility segregation

Relational database management systems (RDBMS) have long been a predominant technology in information systems (IS). Today, however, the ever-changing technology landscape seems to be the proving grounds for many alternative approaches. For instance, alternative databases are currently used in many cloud services that affect everyday life. Similarly, a novel way to design applications has come to fruition. It relies on two concepts; command query responsibility segregation (CQRS) and event sourcing. A combination of the concepts is suggested to mitigate some performance and design issues that commonly arise in traditional information systems development (ISD). However, this particular approach hasn’t sparked interest from of academia yet. This inquiry sets out to find opportunities and challenges that arise from adoption of one of the two concepts, namely CQRS. This is done in relative isolation from event sourcing. In total five interviews were conducted with seven participants using open-ended interview questions derived from design patterns research. The results are five themes that provide guidance to IS professionals evaluating adoption. These are alignment between IT-artifacts and business processes, simultaneous development, flexibility from specific database technology, modularization as a means of implementation and risk of introducing complexity. The results indicate that several themes from domain-driven design are influential to the concept. Additionally, results indicate that CQRS may be a precursor to eventually consistent queries and aids fine-tuning of availability, consistency and partition tolerance considerations. It is concluded that CQRS may facilitate improved collaboration and ease distribution of work. Moreover, it is hoped that the results will help to contextualize CQRS and spark additional interest in the field of IS research. The inquiry suggests further inquiries in other areas. These are among others; extract transform load-patterns, operational transforms, probabilistic bounded staleness and occasionally connected systems

Quality improvement financial incentives for general practitioners

This report reviews outcomes of intervention programmes targeting reductions in potentially avoidable hospitalisations (PAHs) and/or avoidable Emergency Department presentations (ED presentations) among people with chronic disease. The focus is on the role of primary health care and where possible programmes targeting specific vulnerable populations, namely Indigenous Australians, rural and remote residents and those at socioeconomic disadvantage. This report also aimed to examine tQuality improvement includes aspects of self-reflection and benchmarking, with continued evaluation to identify where additional improvements to practice can be made. Measures of the quality of care are typically structure (e.g. related to an organisation’s operations), process (e.g. clinical guidelines or care pathways) or outcomes-based (e.g. physiological indicators). Improvements can be measured in relative or absolute terms. The likelihood of engaging with incentives and the behavioural responses of health professionals are affected by the different characteristics of financial incentives, which may be directed at networks of practices, individual practices, or specific health care professionals. Payments may be offered as a bonus or addition to usual earnings, or may be withheld if practices do not achieve desired outcomes. Payments may be prospective or retrospective and may be linked to fixed thresholds or individual patients.ends in PAHs and ED presentations among people with chronic disease

Reconciling agility and architecture: a theory of agile architecture

The purpose of agile software development is to enable the software development team to respond to change and learn from change so that it can better deliver value to its customer. If an agile software development team spends too much time planning and designing architecture up-front then the delivery of value to the customer is delayed or otherwise compromised, and responding to change can become extremely difficult. Not doing enough architecture design increases exposure to risk and increases the chance of failure. The balance between architecture and agility is not well understood by agile practitioners or researchers. This thesis is based on grounded theory research involving 44 participants from 36 organisations, all working in agile software development and who are either experienced in architecture design or are closely involved with architecture. The thesis presents a theory that describes how agile software teams design an agile architecture with reduced up-front design and which is able to respond to change, helping teams find a balance between architecture and agility. The theory describes six forces that affect the agility of the architecture and up-front design, and five strategies that teams use in response to those forces to determine how much effort they put into up-front design. Understanding these forces and strategies helps agile teams to determine how much up-front design is appropriate in their contexts

Explainable, Security-Aware and Dependency-Aware Framework for Intelligent Software Refactoring

As software systems continue to grow in size and complexity, their maintenance continues to become more challenging and costly. Even for the most technologically sophisticated and competent organizations, building and maintaining high-performing software applications with high-quality-code is an extremely challenging and expensive endeavor. Software Refactoring is widely recognized as the key component for maintaining high-quality software by restructuring existing code and reducing technical debt. However, refactoring is difficult to achieve and often neglected due to several limitations in the existing refactoring techniques that reduce their effectiveness. These limitation include, but not limited to, detecting refactoring opportunities, recommending specific refactoring activities, and explaining the recommended changes. Existing techniques are mainly focused on the use of quality metrics such as coupling, cohesion, and the Quality Metrics for Object Oriented Design (QMOOD). However, there are many other factors identified in this work to assist and facilitate different maintenance activities for developers: 1. To structure the refactoring field and existing research results, this dissertation provides the most scalable and comprehensive systematic literature review analyzing the results of 3183 research papers on refactoring covering the last three decades. Based on this survey, we created a taxonomy to classify the existing research, identified research trends and highlighted gaps in the literature for further research. 2. To draw attention to what should be the current refactoring research focus from the developers’ perspective, we carried out the first large scale refactoring study on the most popular online Q&A forum for developers, Stack Overflow. We collected and analyzed posts to identify what developers ask about refactoring, the challenges that practitioners face when refactoring software systems, and what should be the current refactoring research focus from the developers’ perspective. 3. To improve the detection of refactoring opportunities in terms of quality and security in the context of mobile apps, we designed a framework that recommends the files to be refactored based on user reviews. We also considered the detection of refactoring opportunities in the context of web services. We proposed a machine learning-based approach that helps service providers and subscribers predict the quality of service with the least costs. Furthermore, to help developers make an accurate assessment of the quality of their software systems and decide if the code should be refactored, we propose a clustering-based approach to automatically identify the preferred benchmark to use for the quality assessment of a project. 4. Regarding the refactoring generation process, we proposed different techniques to enhance the change operators and seeding mechanism by using the history of applied refactorings and incorporating refactoring dependencies in order to improve the quality of the refactoring solutions. We also introduced the security aspect when generating refactoring recommendations, by investigating the possible impact of improving different quality attributes on a set of security metrics and finding the best trade-off between them. In another approach, we recommend refactorings to prioritize fixing quality issues in security-critical files, improve quality attributes and remove code smells. All the above contributions were validated at the large scale on thousands of open source and industry projects in collaboration with industry partners and the open source community. The contributions of this dissertation are integrated in a cloud-based refactoring framework which is currently used by practitioners.Ph.D.College of Engineering & Computer ScienceUniversity of Michigan-Dearbornhttp://deepblue.lib.umich.edu/bitstream/2027.42/171082/1/Chaima Abid Final Dissertation.pdfDescription of Chaima Abid Final Dissertation.pdf : Dissertatio

Remerciements ; Coordonnées des établissements ; Liste des acronymesLe Centre de recherche interdisciplinaire en réadaptation du Montréal métropolitain (CRIR) a pour objectif de développer et de préciser par la recherche, qu’elle soit de nature fondamentale ou appliquée, les bases scientifiques et les connaissances nécessaires pour guider des interventions de réadaptation efficaces et efficientes. Pour y parvenir, le CRIR renforce le partenariat entre les universités et les milieux cliniques, forme la relève des futurs chercheurs, entretient la culture de recherche dans les établissements de réadaptation et encourage la diffusion des connaissances. Cet ouvrage collectif sur le thème des accidents vasculaires cérébraux (AVC) est un reflet de ces objectifs. Il rassemble des articles scientifiques, des articles d’érudition et des réflexions cliniques. Il regroupe des écrits de chercheurs, d’intervenants et d’étudiants aux cycles supérieurs. Il s’adresse à ces acteurs, aux gestionnaires des établissements de réadaptation et, dans la mesure du possible, aux personnes ayant des incapacités et à leurs proches. Bien sûr, il n’a pas la prétention de couvrir l’ensemble des recherches actuelles ou des réflexions menées au CRIR sur le thème des AVC, mais c’est l’angle de prise du document, orienté, tout comme l’est notre centre de recherche, tant sur les aspects biomédicaux que psychosociaux de la déficience et de ses traitements, qui le rend, en outre, particulièrement intéressant et original

A mixed-methods investigation of the extent to which routinely collected information can help evaluate the implementaion of screening and brief alcohol interventions in primary health care

PhD ThesisBackground: UK health policy has sought to encourage alcohol screening and brief intervention (ASBI) delivery in primary care, including via pay-for-performance (P4P) schemes. To measure the impact of such policies, a range of data exist, including General Practitioner (GP) Read codes, which record all clinical activity. However, previous studies have highlighted the difficulties of using Read code data for evaluation purposes, with concerns around the distorting effect of P4P on healthcare recording. Against this background, this research investigated whether Read code data can be used to provide a meaningful measure of ASBI implementation in primary care. Methods: Sequential mixed methods design, comprising: (1) systematic literature review to identify what factors influence the recording of routine clinical data by UK primary care physicians; (2) analysis of ASBI Read code data from 16 GP practices in North East England; (3) 14 GP interviews to explore the barriers and facilitators affecting their ASBI recording. Results: (1) Multiple factors shape primary care physicians’ recording of routine data, including structural influencers (such as the design and resourcing of the coding system), and psychosocial factors (including patient characteristics and physicians’ perspectives on their role as care-givers). (2) 287 Read codes exist to record alcohol- related activity however only a small minority are used regularly, generally relating to the identification of alcohol use disorders. Whilst many unused Read codes are associated with relatively rare alcohol conditions, a significant number relate to duplicate or outmoded terminology. Overall, practices associated with higher recorded rates of key ASBI service indicators were signed up to P4P schemes. (3) GP interviews suggested that across all practices, nurse-administered ASBI components were most likely to be provided and coded consistently, with GP-delivery and recording activity far more ad hoc. Conclusion: Whilst routine data may be a valid indicator of more successfully embedded ASBI activity in UK primary healthcare following the introduction of P4P schemes, measuring the impact on delivery at GP level remains challenging due to the deficiency of the available Read code data across a number of quality dimensions.ESRC UKCR
