CASE STUDY · CATHOLIC HEALTHCARE — KRONOS

    Kronos Data Archival — Catholic Healthcare Trust

    Kronos managed Catholic Healthcare Trust's time, attendance and scheduling. Syntra ETL archived ten years of Kronos timekeeping and labor data into the Oracle Autonomous (ATP) archive, with APEX and Power BI reporting, so wage-and-hour, audit and insurance queries can be answered after the system was retired.

    Why Kronos data had to be archived

    Kronos held time, attendance and labor records — the evidence for wage-and-hour compliance, labor audits, and workers'-comp/insurance and legal queries.

    Kronos was CHT's workforce-management system for timekeeping, scheduling and labor tracking. Timecards, worked hours, accruals and labor distribution are central to wage-and-hour compliance and are frequently requested in labor audits, workers'-compensation claims and employment litigation — with multi-year retention.

    Ten years of Kronos data was archived into the Oracle ATP archive as part of the five-system project (~8 TB, ~150,000 attachments total), letting CHT retire Kronos while keeping the records searchable and reportable.

    Challenges we solved

    Retiring Kronos came with real data-engineering challenges.

    End-of-life applications

    The source systems were out of vendor support — raising security, compliance and continuity risk. Archiving and decommissioning removed that risk.

    📄

    Little documentation, few users left

    Minimal documentation survived and few functional users remained who understood the applications, so we reverse-engineered the data model and validated it with the business.

    🔌

    Direct SQL database access

    We connected directly to the Kronos SQL database to extract timekeeping, accrual and labor history in full.
