    From Legacy Silos to Single View in the Public Sector

    Public institutions accumulate legacy silos over decades, fragmenting the representation of the citizen across systems. This article explores how an entity-centric Single View architecture, built on MongoDB, transforms integration from runtime joins into a persistent operational model for the Public Sector.

  • Scaling MongoDB to 100K+ Writes per Second

    Sustaining 100K+ writes per second in MongoDB is not a tuning trick — it is an architectural decision. This article breaks down how to design a sharded cluster using realistic Atlas hardware (32GB RAM, 8 CPU, standard storage) and achieve linear horizontal scaling through deterministic shard key distribution, clean write paths, and disciplined index strategy.

    Master Data Management and Golden Records

    Master Data Management is not about consolidating records or choosing a system of record.
    It is about defining how truth is constructed when systems disagree.

    This monograph presents a production-grade MDM pattern based on attribute-centric Golden Records, explicit governance, and temporal versioning. From ingestion to conflict resolution, it shows how truth is composed, explained, and preserved over time in real enterprise architectures.
