Statistics estate before modernisation
Statistics estate before modernisation
The estate as it runs today, in three zones read left to right. COLLECTION holds a CAPI survey tool on PostgreSQL, hand-maintained ASP.NET web portals, and an external civil registry outside the organisation's control. PROCESSING holds the Windows shared drive with no version control — the primary bottleneck and focal component — plus analyst workstations running SPSS, SAS, Stata and Excel, and an on-premises SQL Server tinted as a likely survivor of the migration. DISSEMINATION holds the legacy publishing portal, the second bottleneck, a static public website refreshed quarterly, and external ministry partners. Hand-offs are named by their real transport: CSV, EMAIL, COPY, LOAD, EXCEL, WEB and CSV download. Identity and observability footer bars span the canvas below the zones and emit no connectors.
