Features of microservices architecture in e-commerce systems

The development of information system architectures for e-commerce is a crucial task for busi-nesses in today's digital environment. This article presents a comparative analysis of different types of information system architectures used in e-commerce. The paper examines the specific characteristics of e-commerce and the requirements of web applications that support electronic business operations. Traditional monolithic architecture, microservices architecture, and server-less architecture have been characterized, and their advantages and disadvantages have been identified. Technological solutions in the field of e-commerce development have been studied to create an efficient and user-friendly platform. The article highlights such key architectural aspects as scalability, flexibility, deployment speed and management, reliability, and develop-ment and operational costs. The impact of each architecture type on performance and alignment with e-commerce business needs has been analyzed. This analysis will assist in the creation or modernization of information systems for e-commerce, enabling an informed choice of archi-tectural approach. The article specifically examines the advantages and disadvantages of micro-services architecture for developing e-commerce web applications, particularly using the Spring Boot framework. It explores how microservices can provide modularity and facilitate the devel-opment, deployment, and maintenance of e-commerce web applications. Such challenges of mi-croservices architecture as managing and coordinating services, as well as addressing data con-sistency and transaction management in distributed environments have been discussed. Some possible approaches and technical tools to overcome these challenges in the context of e-commerce web applications based on Spring Boot have been considered.

Perancangan Arsitektur Enterprise FMIPA UNTAN Menggunakan Kerangka Kerja TOGAF Berbasis SOA

The research aims to develop an Enterprise Architecture from FMIPA UNTAN, this is based on the many individual information systems that have been developed by FMIPA UNTAN which are not integrated in data and technology. This situation results in overlapping data that can affect the effectiveness of decision making within the organization. The designed Enterprise Architecture implements the concept of service-oriented architecture in order to support the integration between the business layer and the organization's technology layer. To support the research, several concepts are used, such as TOGAF as a framework for developing Enterprise Architecture, Service Oriented Architecture as a supporter for integration of architectural layers, and Archimate and Business Process Modeling Notation as a modeling language used to create architectural artifacts. The stages of the research included problem identification, the Enterprise Architecture development process followed the stages of TOGAF ADM namely the preliminary phase, architectural vision, business architecture, information system architecture, technology architecture, and making an architecture implementation roadmap. The results of the development of Enterprise Architecture are architectural artifacts consisting of catalogs, matrices, and diagrams of business, information system, and technology architecture. Based on the design results, it is found that the Enterprise Service Bus concept in Service Oriented Architecture can be used to support application and data integration in organization, as well as the concept of service access can bridge the gap between the business layer and the technology layer.

Decision-making System as a Service in the Computing Cloud

Cloud computing presents scientists and engineers with new challenges related to the architecture of information systems and their use. This paper addresses the problem of deployment of decision supporting system in computing cloud. The author of the document presented the application of this approach that lies on intelligent discovery of web services within geographic information systems. Many important aspects of nowadays IT systems have been considered like the domain of Web GIS, network of agents architecture, semantics and ontology, integration of external knowledge bases, deployment of applications into the cloud. It has been proven that based on them, it is possible to create a software that uses a natural language to submit queries to a system whose operating environment is a PaaS (Platform as a Service) class platform. Another aspect discussed in this article was the approach to build so-called virtual organizations in which data and knowledge exchange takes place via web services. As an example, integration with Google Geocoding API is shown, where the web API provides geographic location based on the location expressed in natural language, e.g. home address, tourist point.

Data Locality in High Performance Computing, Big Data, and Converged Systems: An Analysis of the Cutting Edge and a Future System Architecture

Big data has revolutionized science and technology leading to the transformation of our societies. High-performance computing (HPC) provides the necessary computational power for big data analysis using artificial intelligence and methods. Traditionally, HPC and big data had focused on different problem domains and had grown into two different ecosystems. Efforts have been underway for the last few years on bringing the best of both paradigms into HPC and big converged architectures. Designing HPC and big data converged systems is a hard task requiring careful placement of data, analytics, and other computational tasks such that the desired performance is achieved with the least amount of resources. Energy efficiency has become the biggest hurdle in the realization of HPC, big data, and converged systems capable of delivering exascale and beyond performance. Data locality is a key parameter of HPDA system design as moving even a byte costs heavily both in time and energy with an increase in the size of the system. Performance in terms of time and energy are the most important factors for users, particularly energy, due to it being the major hurdle in high-performance system design and the increasing focus on green energy systems due to environmental sustainability. Data locality is a broad term that encapsulates different aspects including bringing computations to data, minimizing data movement by efficient exploitation of cache hierarchies, reducing intra- and inter-node communications, locality-aware process and thread mapping, and in situ and transit data analysis. This paper provides an extensive review of cutting-edge research on data locality in HPC, big data, and converged systems. We review the literature on data locality in HPC, big data, and converged environments and discuss challenges, opportunities, and future directions. Subsequently, using the knowledge gained from this extensive review, we propose a system architecture for future HPC and big data converged systems. To the best of our knowledge, there is no such review on data locality in converged HPC and big data systems.

3LGM2IHE: Requirements for Data-Protection-Compliant Research Infrastructures-A Systematic Comparison of Theory and Practice-Oriented Implementation.

The TMF (Technology, Methods, and Infrastructure for Networked Medical Research) Data Protection Guide (TMF-DP) makes path-breaking recommendations on the subject of data protection in research projects. It includes comprehensive requirements for applications such as patient lists, pseudonymization services, and consent management services. Nevertheless, it lacks a structured, categorized list of requirements for simplified application in research projects and systematic evaluation. The 3LGM2IHE ("Three-layer Graphbased meta model - Integrating the Healthcare Enterprise [IHE] " ) project is funded by the German Research Foundation (DFG). 3LGM2IHE aims to define modeling paradigms and implement modeling tools for planning health care information systems. In addition, one of the goals is to create and publish 3LGM2 information system architecture design patterns (short "design patterns") for the community as design models in terms of a framework. A structured list of data protection-related requirements based on the TMF-DP is a precondition to integrate functions (3LGM2 Domain Layer) and building blocks (3LGM2 Logical Tool Layer) in 3LGM2 design patterns. In order to structure the continuous text of the TMF-DP, requirement types were defined in a first step. In a second step, dependencies and delineations of the definitions were identified. In a third step, the requirements from the TMF-DP were systematically extracted. Based on the identified lists of requirements, a fourth step included the comparison of the identified requirements with exemplary open source tools as provided by the "Independent Trusted Third Party of the University Medicine Greifswald" (TTP tools). As a result, four lists of requirements were created, which contain requirements for the "patient list", the "pseudonymization service", and the "consent management", as well as cross-component requirements from the TMF-DP chapter 6 in a structured form. Further to requirements (1), possible variants (2) of implementations (to fulfill a single requirement) and recommendations (3) were identified. A comparison of the requirements lists with the functional scopes of the open source tools E-PIX (record linkage), gPAS (pseudonym management), and gICS (consent management) has shown that these fulfill more than 80% of the requirements. A structured set of data protection-related requirements facilitates a systematic evaluation of implementations with respect to the fulfillment of the TMF-DP guidelines. These re-usable lists provide a decision aid for the selection of suitable tools for new research projects. As a result, these lists form the basis for the development of data protection-related 3LGM2 design patterns as part of the 3LGM2IHE project.

Toward an information systems architecture model for university hospitals: A case study in a Brazilian public hospital

AbstractThe implementation of information systems (IS) architecture is a step in constructing enterprise architecture (EA) according to The Open Group Architecture Framework (TOGAF) and can introduce notable benefits in supporting the management and governance of information and communications technology (ICT) in organizations. However, the literature lacks models that support the construction of IS architectures in university hospitals (UHs). The Hospital das Clínicas of the Federal University of Pernambuco (HC‐UFPE) is a large UH that confronts ICT misalignments of with other internal areas. In this context, this study investigates and proposes an IS architecture model for UHs through a case study conducted at HC‐UFPE. The data collection methodology for constructing the IS architecture of this hospital was based on consultations with institutional documents, interviews with strategic stakeholders, and participant observations in the hospital's ICT sector. Open coding and data triangulation were used to analyze the data. This study presents two main contributions. (1) The development of a model used to assist in the construction of IS architecture for UHs. The model developed in this study has a practical application with the TOGAF 9.2 framework and Archi software for constructing an IS architecture for HC‐UFPE. (2) The development and delivery of an HC‐UFPE IS architecture to support the hospital's ICT governance, providing, through EA artifacts, a holistic view of the hospital's current and future ICT processes, in addition to the identification of gaps, challenges, and viable solutions to be considered for decision making to improve service delivery and ICT alignment with other hospital areas.

An Application of a Decision Support System Enabled by a Hybrid Algorithmic Framework for Production Scheduling in an SME Manufacturer

In this research, we present a hybrid algorithmic framework and its integration into the precise production scheduling system of a Greek metal forming factory. The system was created as a decision support tool to assist production planners in arranging weekly production orders to work centers and other manufacturing cells. The functionality offered includes dispatching priority rules, bottleneck identification for capacity planning, production order reallocation to alternate work centers and planning periods, interchangeable scheduling scenarios, and work-in-process availability checks based on bill of materials (BOM) precedence constraints. As a consequence, a solid short-term production plan is created, capable of absorbing shop floor risks such as machine failures and urgent orders. The primary design ideas are simplicity, ease of use, a flexible Gantt-chart-based graphical user interface (GUI), controllable report creation, and a modest development budget. The practical application takes place in a make-to-stock (MTS) environment with a complicated multi-level production process, defined due dates, and parallel machines. A critical component is the integration with legacy applications and the existing enterprise resource planning (ERP) system. The method adopted here avoids both overburdening the existing information system architecture with software pipeline spaghetti, as is common with point-to-point integration, and overshooting implementation costs, as is often the case with service-oriented architectures.

Digital Transformation Planning Based on Big Data Technology (Case Study: XYZ Bank)

Bank XYZ is one of the regional government-owned banks which as of August 16, 2021 has a total percentage of customers who have dormant accounts reached 50.43%. This happens because currently the development of the marketing strategy used by Bank XYZ is still based on the products and services owned by Bank XYZ, not referring to customer needs. For this reason, the purpose of this research is to make a digital transformation plan that can be used by Bank XYZ in order to become a customer-centric bank using Big Data technology. The method used to carry out this research is to use the Big Data Framework for Agile Business (BDFAB). The results of this study includes mapping data requirements and Big Data technology for Bank XYZ, the impact to business processes, proposals for changes in information system architecture, planning for quality control mechanisms, to changes in organizational structure so that the benefits obtained by Bank XYZ are a more personalized marketing approach to customers, increased accuracy in offering bank products and services based on customer profiles, needs, behavior, and interests, as well as increased customer engagement and customer satisfaction.

A Novel Tightly Coupled Information System for Research Data Management

Most research projects are data driven. However, many organizations lack proper information systems (IS) for managing data, that is, planning, collecting, analyzing, storing, archiving, and sharing for use and re-use. Many research institutions have disparate and fragmented data that make it difficult to uphold the FAIR (findable, accessible, interoperable, and reusable) data management principles. At the same time, there is minimal practice of open and reproducible science. To solve these challenges, we designed and implemented an IS architecture for research data management. Through it, we have a centralized platform for research data management. The IS has several software components that are configured and unified to communicate and share data. The software components are, namely, common ontology, data management plan, data collectors, and the data warehouse. Results show that the IS components have gained global traction, 56.3% of the total web hits came from news users, and 259 projects had metadata (and 17 of those also had data resources). Moreover, the IS aligned the institution’s scientific data resources to universal standards such as the FAIR principles of data management and at the same time showcased open data, open science, and reproducible science. Ultimately, the architecture can be adopted by other organizations to manage research data.

Perencanaan Arsitektur Enterprise Menggunakan Kerangka Kerja Togaf ADM Pada Dinas Perkebunan Dan Peternakan Kab. Muaro Jambi

The application of enterprise architecture aims to create alignment between business and information technology for the current and future needs of organizations. The success of implementing enterprise architecture cannot be separated from how an organization plans and designs the enterprise architecture. Planning and designing enterprise architecture requires a complete and easy-to-use methodology. In this study, a case study was conducted for strategic planning of information systems by applying the TOGAF ADM method with the help of the value chain model and other modeling tools at the Plantation and Livestock Service Office of Muaro Jambi Regency. The stages of the TOGAF ADM methodology are translated into enterprise architecture modeling, namely vision architecture, business architecture, information systems architecture and technology architecture. The results of the enterprise architecture modeling with the TOGAF ADM methodology provide a basis for overcoming the problem of lack of data integration and lack of information system support for business functions.

Assessment of it Systems Architecture in the Context of Big Data Processing for Smart Cities Development

Effective use of Big Data can significantly support the development of smart cities and the new digital economy. The aim of the article is a multi-criteria evaluation of IT systems in terms of Big Data processing, taking into account the support for the development of smart cities. The article includes theoretical and empirical research. The adopted criteria for assessing the architecture of IT systems relate to barriers to the implementation of the digital economy in smart cities and the guidelines of international data strategies. The evaluation covered, among other things, cybersecurity and the effectiveness of organizing, storing, and producing new information. The research results allowed us to identify the key factors of Big Data processing efficiency. Based on the research results, an effective model of Big Data processing in organizations was developed. In particular, various data models were analyzed as one of the main elements of software architecture of information systems. The research also focused on data processing techniques such as data warehousing, machine learning, and distributed computing. The efficiency factors of IT systems identified in the research reduce barriers to developing global data strategies and smart cities.

The impact of enterprise architecture management on information systems architecture complexity

ABSTRACT Significant investments in information systems (IS) over the past decades have led to increasingly complex IS architectures in organisations, which are difficult to understand, operate, and maintain. We investigate this development and associated challenges through a conceptual model that distinguishes four constituent elements of IS architecture complexity by differentiating technological from organisational aspects and structural from dynamic aspects. Building on this conceptualisation, we hypothesise relations between these four IS architecture complexity constructs and investigate their impact on architectural outcomes (i.e., efficiency, flexibility, transparency, and predictability). Using survey data from 249 IS managers, we test our model through a partial least squares (PLS) approach to structural equation modelling (SEM). We find that organisational complexity drives technological complexity and that structural complexity drives dynamic complexity. We also demonstrate that increasing IS architecture complexity has a significant negative impact on efficiency, flexibility, transparency, and predictability. Finally, we show that enterprise architecture management (EAM) helps to offset these negative effects by acting as a moderator in the relation between organisational and technological IS architecture complexity. Thus, organisations without adequate EAM are likely to face large increases in technological complexity due to increasing organisational complexity, whereas organisations with adequate EAM exhibit no such relation.

Enterprise architecture-based ISA model development for ICT benchmarking in construction-case study

<span>Building on a coincided in progress paper, this paper constructs and evaluate an information systems architecture (ISA) model for the Bahraini architecture, engineering and construction (AEC) sector, from the lens of enterprise architecture (EA). This model acts as an information and communication technology (ICT) barometer tool to identify and benchmark the ICT’s gaps, duplicative levels, and future investments. Following the design science research, this paper and throughout a utilization of a tailored version of the open group architectural framework (TOGAF), embedded into a rigorous case study approach, the construction, testing, and evaluation of the conceptual ISA model is approached to benchmark the ICT measurement. Empirically, the study revealed the appropriateness of the model and the ability to identify the availability of 28 groups of 38 individual ICT applications in the Bahraini AEC sector and benchmark them to score an average of 18.5% against 17 countries that scored an average of 18.6%.</span>

LDL Reduction and Risk of Diabetes in Veteran Statin Users.

While statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) reduce cardiovascular morbidity and mortality, there is controversy regarding a potentially causal link with incident diabetes mellitus (DM). This association may partially be due to confounding by indication; since prescription guidelines encourage statin use among those diagnosed with DM, this may encourage their prescription among those with elevated blood glucose in the absence of DM diagnosis. The study examined the association between low-density lipoprotein (LDL) reduction following initiation of statin use and new-onset DM among veterans. We conducted a retrospective cohort study using data from the James A. Haley Veteran's Hospital in Tampa, Florida. Patients with a visit between January 2007 and December 2011 were selected from the Veterans Information Systems and Technology Architecture system. Individuals were classified into categories of statin usage based on LDL reduction percentages and frequency-matched with controls. The primary outcome of interest was incident DM. There was a significant association between LDL reduction and DM which was higher in lower LDL reduction groups (low response hazard ratio [HR]: 2.12, 95% CI: 1.62, 2.79; moderate response HR: 1.85, 95% CI: 1.40, 2.45; high response HR: 1.24, 95% CI: 0.74, 2.07). This association may partially be explained by potential lifestyle modifications individuals may make when prescribed a statin which may reduce their risk of DM independent of the statin usage. This research has demonstrated a protective association between greater LDL reduction and DM at the individual level while reenforcing the evidence of an association between statin usage and DM.

Designing Information System Architecture Based on Education 4.0 Case Study: Senior High School Institutions of Indonesia

The development of information technology that has occurred to date has made information technology necessary in an organization's business in various fields. Information technology support is very much needed in the current era of globalization because it can increase business effectiveness and efficiency. Utilization of technology optimally and in line with business processes is the main thing in developing the application of information technology. Senior High School (SHS) is one of the educational agencies in Indonesia that is developing following the development of technology. SHS institutions realize how important it is to apply technology in supporting their business processes. At present, the SHS institution has been helped with technology such as the use of Excel in all recording in schools, but the SHS institution itself has not implemented optimal and integrated information technology in every field of school activity which often occur in data loss, delivery of information both in terms of learning as well as school activities that require a long time, and not integrated the school system. The application of information technology that will be used by a school must be by the goals of the school so that the application can help the school well in achieving school business goals, the use of Enterprise Architecture (EA) in the application of information technology to help analyze information technology planning by SHS institutions. This study will use The Open Group Architecture Framework (TOGAF) to assist in application planning. The final results of this study proposed six application blueprints namely Academic System, Non-Academic System, Procurement Management, Financial Management, HR Management, and Data Management which are tailored to the business process and the needs of the SHS institution.

Enterprise Architecture Planning for College Information Systems using the TOGAF-ADM Framework and ISO 27001

The planning for the development of Information Systems and Technology is carried out with the main goal of realizing the Vision and Mission of Higher Education. The Information System design framework used is TOGAF (The Open Group Architecture Framework) - ADM (Architecture Development Methode), in that framework consists of several steps of implementing a representative architectural design to be used in architectural design at the Toyota Indonesia Community Academy which focuses on Business, Data, Applications and Technology. For the information system security management system, TOGAF-ADM can collaborate with ISO 27001:2013, where when we plan the development of the enterprise information system architecture for universities, we must also focus on information system security in accordance with the information system security system contained in the ISO 27001 :2013. By using a combination framework between TOGAF-ADM and ISO 27001, it is very appropriate to be used as a method for planning Enterprise Architecture in Higher Education that prioritizes business, applications and technology and adopts an information security management system from ISO 27001 .
