Models

A scenario-based headcount planning system. The system tracks the current org (departments, locations, cost centers, jobs, employees, positions) as the source-of-truth baseline, and lets planners draft alternative future-state plans through scenarios containing staged headcount actions (add, eliminate, transfer). Approved scenarios materialize into real position records, which can then be handed off to recruiting via lightweight hiring requisitions.

The Northwind sample database models the trading operations of a fictional specialty-foods company. It tracks the products the company buys from suppliers and sells to customers, the orders those customers place, the employees who process the orders, and the shippers who deliver them. Sales territories and regions are also modeled, along with which employees are assigned to which territories.

A lessee-side system for tracking equipment lease contracts with vendors, the individual assets they cover, the planned and actual payment streams they generate, and the budgets against which those payments are measured. Users are finance analysts, contract owners, and cost-center managers who need to answer questions like "what is our total lease obligation next quarter?", "which contracts are over budget?", and "which assets are still under lease and where are they deployed?". The data model is platform-agnostic; budgeting is modeled at the cost-center / fiscal-period grain so variance analysis against actual payments is straightforward downstream.
