Everything must stay native to Visual FoxPro; however, if a lightweight helper tool (e.g., SQL Server Express or Power BI for the front-end analytics layer) makes sense, I’m open to your recommendation, provided the core remains in VFP. Deliverables • Updated schema for the current VFP database, fully documented • Cleaned and optimised data set with repeatable scripts • A brand-new VFP database built on the revised architecture • A suite of parameter-...
