Since the inception of MongoDB, we’ve believed that as companies embrace digital transformation, their developers’ biggest challenges come from working with data: ● Demands for higher developer productivity and faster time to market – where release cycles are compressed to days and weeks – are being held back by rigid relational data models and traditional waterfall development practices. -

Main Page 1 Main Page FLOSSMETRICS/ OpenTTT guides FLOSS (Free/Libre open source software) is one of the most important trends in IT since the advent of the PC and commodity software, but despite the potential impact on European firms, its adoption is still hampered by limited knowledge, especially among SMEs that could potentially benefit the most from it. This guide (developed in the context of the FLOSSMETRICS and OpenTTT projects) present a set of guidelines and suggestions for the adoption of open source software within SMEs, using a ladder model that will guide companies from the initial selection and adoption of FLOSS within the IT infrastructure up to the creation of suitable business models based on open source software. The guide is split into an introduction to FLOSS and a catalog of open source applications, selected to fulfill the requests that were gathered in the interviews and audit in the OpenTTT project. The application areas are infrastructural software (ranging from network and system management to security), ERP and CRM applications, groupware, document management, content management systems (CMS), VoIP, graphics/CAD/GIS systems, desktop applications, engineering and manufacturing, vertical business applications and eLearning. This is the third edition of the guide; the guide is distributed under a CC-attribution-sharealike 3.0 license. The author is Carlo Daffara ([email protected]).

MariaDB Server is the foundation of MariaDB Platform – an integrated suite of enterprise-grade products for storing and accessing data. MariaDB Platform is the only open source database with the same enterprise features found in proprietary databases, including Oracle Database compatibility (e.g., PL/SQL compatibility), temporal tables, sharding, point-in-time rollback, and transparent data encryption. And all of this comes at a much lower total cost of ownership (TCO) than Oracle. MariaDB has displaced MySQL in leading Linux distributions, including Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES). MariaDB Platform is used on premises, as well as on public and private cloud infrastructure platforms, including OpenStack. It is a trusted, proven, and reliable replacement for proprietary databases. 3 Lower TCO without Lowering Standards WHITEPAPER TOTAL COST OF OWNERSHIP & SCALING BENEFITS MariaDB Platform frees companies from the costs, constraints, and complexity of proprietary databases, enabling them to reinvest in what matters most – rapidly developing innovative, customer-facing applications. -

Next billion devices could be reached within less than three years. More businesses move toward employees mobility. Powerful lightweight computing devices and low cost mobile connectivity paved the way for data-driven applications. Powerpoint Templates Page 2 Why Mobile Databases? Mobile data-driven applications enable us to access any data from anywhere, anytime. Examples: Salespersons can update sales records on the move. Reporters can update news database anytime. Doctors can retrieve patient’s medical history from anywhere. Mobile DBMSs are needed to support these applications data processing capabilities.

Multi-Master Database Replication and E-Learning
EXAMENSARBETE I KOMMUNIKATIONSSYSTEM 120 HP, AVANCERAD NIVÅ STOCKHOLM, SVERIGE 2015 Multi-Master Database Replication and e-Learning THEORETICAL AND PRACTICAL EVALUATION MATTIAS HOLMGREN KTH KUNGLIGA TEKNISKA HÖGSKOLAN SKOLAN FÖR INFORMATIONS- OCH KOMMUNIKATIONSTEKNIK Multi-Master Database Replication and e-Learning – Theoretical and Practical Evaluation Mattias Holmgren KTH School of Information and Communication Technology (ICT) Stockholm, Sweden Supervisor: Björn Pehrson Examiner: Markus Hidell Abstract This research has investigated the possibility to combine multi-master database replication technolo- gies together with a LEMP-stack on tiny servers to increase the availability of e-Learning services in remote areas in Tanzania. The aim was to evaluate the combination of Symmetric DS for multi mas- ter database replication and conflict detection and resolution with the e-learning system Moodle. This was done by conducting a literature study of relevant technologies followed by implementation and configuration at the location. The conclusion was that the technologies, software and hardware chosen for the project were configurable in theory but not viable to implement and maintain in prac- tice. Keywords: Database replication, eLearning, Collision detection and resolution, Moodle, Open Uni- versity of Tanzania i Sammanfattning Detta examensarbete har undersökt möjligheterna att kombinera multi-master databasreplikerings- tekniker tillsammans med en LEMP-stack på små servrar för att öka tillgängligheten av e-Learning tjänster i avlägsna områden i Tanzania. Målet var att utvärdera kombinationen av Symmetric DS för databas synkronisering och kollitionsdetektering och resolution med e-Learning systemet Moodle. Detta gjordes genom att en litteraturstudie genomfördes och uppföjdes av implementation och konfiguration på plats i Tanzania. Slutsatsen var att de för projektet utvalda teknologierna, mjukvaran och hårdvaran var konfigurerbar i teorin men ohållbart kostsam att implementera i praktiken. -

Paper—A Platform for Electronic Health Record Sharing in Environments with Scarce Resource… A Platform for Electronic Health Record Sharing in Environments with Scarce Resource Using Cloud Computing https://doi.org/10.3991/ijoe.v16i09.13187 Muhamad Fitra Kacamarga, Arif Budiarto (), Bens Pardamean Bina Nusantara University, Jakarta, Indonesia [email protected] Abstract—One of the main objectives of Electronic Health Record (EHR) is the transferability of patient data from one location to another. Many locations with scarce resources, particularly unreliable internet connectivity, face difficul- ties in accessing and sharing EHR data. This article presents our proposed design that utilizes Amazon Web Services (AWS) for a sharing mechanism platform among distributed healthcare organizations found in an environment with scarce resources. We proposed the use of database replication mechanism and REST (Representational State Transfer) web service to perform information exchange among health organizations and public health information systems. Keywords—EHR, cloud computing, database replication, web service. 1 Introduction An emerging development of information technology (IT) has provided benefits for health care institutions to effectively collect and manage vast amount of patients’ data in clinical settings including Electronic Health Record (EHR), medical image data, ge- netics data, and personal daily activities data [1]–[5]. Among all these data, EHR is the most comprehensive and important data source which can explain the patients’ condi- tion over time. EHR is the digital format of patients’ medical record that can be shared with multiple health care organizations for clinical purposes [6]. One of the main ob- jectives for an EHR implementation is the transferability of patient data from one loca- tion to another; this is especially crucial due to the multi-locale nature of data collection within the healthcare service environment.
