Multi-Master Database Replication and e-Learning – Theoretical and Practical Evaluation

Abstract [sv]

Detta examensarbete har undersökt möjligheterna att kombinera multi-master databasreplikeringstekniker 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.

Abstract [en]

This research has investigated the possibility to combine multi-master database replication technologies 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 master 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 practice.
