API Governance in the Boomi Era: Best Practices

API governance defines how an organization designs, secures, and manages the lifecycle of its interfaces. Without consistent rules, APIs grow unevenly, security policies diverge, and documentation becomes outdated. Boomi’s API Management module provides a structured approach to governance, making it possible to apply uniform standards across multiple environments. This article reviews the main components of API governance, practical implementation steps in Boomi, and several examples from real enterprise projects.

Java FHIR Subscriptions in Healthcare: Event-Driven Updates Without Polling (R4/R4B)

Polling clinical systems is slow, noisy, and brittle. Interfaces burn capacity on repeated checks, dashboards drift out of date, and edge cases multiply under load. FHIR Subscriptions offer a cleaner path: publish changes as events and deliver them to the consumers that actually need them. With Java 21, Spring Boot 3, and HAPI FHIR, a team can implement subscriptions that scale, respect privacy, and survive real hospital traffic. This article explains when subscriptions beat polling, shows a boundary-first architecture in Java, covers consent and audit details, and finishes with a 30-day rollout plan and signals that prove the approach works.

Dedicated Engineering Teams for Europe: A Predictable Model for Integration, Data & BI

European buyers optimise for predictability, compliance, and fit. Rates matter, but they rarely decide the outcome; steady delivery, clear scope control, and security hygiene do. This article describes a dedicated-team model that holds up under multi-month integration and analytics work: a small pod with ownership, a transparent operating rhythm, measurable delivery health, and privacy controls aligned to EU expectations. You’ll find how we structure roles and governance, which metrics keep stakeholders informed without noise, what compliance artefacts procurement asks for, and a 30-day onboarding plan you can run without halting current initiatives.

Designing a Healthcare Semantic Model in Power BI: Trustworthy Dashboards, Predictable Refresh, and Privacy That Holds

Hospitals don’t need flashier visuals; they need answers they can trust at the point of care. When Power BI projects mirror source systems or bury privacy behind permissions, dashboards slow down, clinicians lose trust, and ops revert to spreadsheets. This article lays out a healthcare-first approach to Power BI: a semantic model that reflects clinical reality (encounters at the right grain, vitals/labs as events), performance patterns that survive peak hours (Incremental Refresh, Aggregations, Composite models), and safety rails on the surface (freshness, completeness, RLS, governed exports). A focused 30-day plan closes things out so you can harden one high-impact dashboard without pausing delivery.

From HL7v2 to FHIR R4 with Java: Interoperable Services, Audit-by-Design, and Safer Data Flows

Healthcare interfaces break in predictable places: retries create duplicate encounters, partial updates corrupt charts, exports leak PHI, and a Friday mapping “hotfix” ruins Monday’s ward round. Java 21 and Spring Boot 3 give you reliable primitives - virtual threads, structured concurrency, records - but resilient clinical integration still relies on operational patterns: idempotent messaging at the HL7 boundary, strict FHIR validation, consent-aware access, and an audit trail you can actually read. This article lays out a boundary-first architecture for HL7v2 → FHIR R4 bridges, shows how to validate and map safely with HAPI FHIR, and explains privacy controls that keep you out of trouble. We close with a 30-day rollout plan and pragmatic signals to prove it works in real clinics.

A Telco Data Model in Power BI: From CDRs to ARPU/Churn Dashboards Without Query Timeouts

Telecom data never sits still. Calls, sessions, handovers, outages - each minute brings a new peak somewhere in the network. Dashboards that feel fine during development often stall in production because the model mirrors operational tables, filters scan months, and definitions drift between reports. This article shows how to shape a telco-ready semantic model in Power BI: CDRs and network counters at the right grain, measures the NOC trusts, and performance features that keep refresh predictable. You’ll also get lightweight governance patterns (freshness, completeness, ownership) and a 30-day rollout plan you can run alongside current work.

Telco-Grade Java Microservices: Resilient Provisioning, CDR Pipelines, and Observability Under Real Load

Telecom workloads punish weak designs: cascaded timeouts during launches, duplicate activations from “harmless” retries, and CDR jobs that lag exactly when usage spikes. Java 21 LTS gives you reliable building blocks - virtual threads, structured concurrency, modern records - yet stability still depends on operational patterns: explicit state, idempotent commands, guarded dependencies, and observability tied to action. This article lays out a practical approach that holds under real traffic: how to model provisioning flows, move and rate CDRs without double-counting, measure what matters (p50/p95/p99, freshness, backlog), and roll out changes safely. A focused 30-day plan at the end shows how to harden one service without pausing delivery.
