PBDB: Payroll and Billing Database
This database existed as a customized bridge between the client's time tracking system (a python/postgresql application), and their accounting system (MSSQL-based). PBDB itself was MSSQL-based and was written mostly in Visual Basic. It existed primarily to automate processes that had previously been highly manual. The application grew to include an invoicing section, an extensive reporting section, and even a business forecasting section. Unfortunately, I have little to show as the application was highly dependent on two proprietary software products I can no longer access.
