Migrating Monolithic E-commerce Systems to Microservices: A Systematic Review of Event-Driven Architecture Approaches.
Abstract
The transformation from monolithic to microservices architectures in e-commerce systems has gained significant traction as organizations seek enhanced scalability, resilience, and operational agility. This systematic review examines the current state of research on migrating monolithic e-commerce systems to microservices using event-driven architecture (EDA) approaches. Following PRISMA guidelines, we analyzed 11 relevant studies focusing on decomposition frameworks, migration methodologies, and implementation strategies specific to e-commerce contexts. Our findings reveal that event-driven architectures provide superior scalability and fault tolerance compared to traditional synchronous communication patterns, with asynchronous messaging showing 30-40% better performance under high load conditions. Key migration approaches include the Strangler Fig Pattern, Domain-Driven Design (DDD) decomposition, and process mining-based identification of service boundaries. However, challenges persist in data consistency management, service communication complexity, and organizational alignment during migration. The review identifies critical gaps in standardized metrics for evaluating migration success and limited tooling support for automated decomposition in e-commerce-specific contexts. This study contributes to the understanding of event-driven microservices migration patterns and provides actionable insights for practitioners undertaking e-commerce modernization initiatives.

A Comparative Solution using Laplace Transform Method on Kirchhoff Second Law with Angular Frequency Effect.
Abstract
This study shows the unique solution to a second order non homogenous linear differential equation using the Laplace transform method with two mathematical models for sum of voltage drop across the R-L-C circuit with required boundary conditions. Solutions for the charge flowing across the circuit was obtained using the Laplace transform with parameters such as Inductance L, resistance R, capacitance C, Electromotive force (EMF) and angular frequency, all having an effect on the total charge flowing across the circuit. The results obtained showed that the increase in the capacitance and EMF increased the electric charge flowing across the circuit. The presence of the angular frequency in the second mathematical model decreased the electric charge as the resistance increased when compared to the first Mathematical model where the electric charge increased. The increase in the inductance increased the electric charge in the second mathematical model when compared to the first mathematical model where the electric charge decreased. The results of the solution from the second mathematical model proved to be better and safer for electrical/mechanical appliances with the effect of angular frequency.

Contextual Determinants of Facilities Management Strategies in the Lagos Commercial Real Estate Sector.
Abstract
Facilities Management (FM) plays an increasingly strategic role in sustaining the performance of commercial properties, particularly in rapidly urbanising contexts such as Lagos, Nigeria. This study examines the contextual determinants shaping FM strategies in the Lagos commercial real estate sector. Drawing on a survey of 167 registered facility managers, the research employed descriptive and inferential statistics to evaluate the effectiveness of various strategies, including preventive maintenance, Total Facilities Management (TFM), customer service protocols, and technology integration. Findings indicate that preventive maintenance and TFM are perceived as the most effective approaches, yielding significant benefits in asset longevity, cost control, and tenant satisfaction. However, the study highlights persistent challenges, including limited adoption of advanced technologies due to infrastructural constraints, financing barriers, and workforce skill gaps. The analysis, framed within contingency theory, underscores that FM effectiveness depends on aligning strategies with contextual realities such as building morphology, economic pressures, and regulatory environments. The study concludes that while Lagos is transitioning towards integrated FM models, uneven implementation limits overall outcomes. It recommends investment in workforce development, staged technology adoption, vendor governance, and sustainability measures to strengthen resilience. The findings contribute to both scholarship and practical decision-making in facilities management.
