My manual-entry workflow has outgrown simple spreadsheets and text files, so I need everything consolidated in a proper database system. The records contain both text and numerical fields, and I want an interface that lets me add, edit, search, and export them with zero fuss. I’m open to guidance on the underlying engine—whether that ends up being PostgreSQL/MySQL, a NoSQL option, or even a hybrid approach. The key is that the choice is clearly justified and future-proof. Deliverables • A well-structured schema that handles mixed data gracefully • A lightweight web or desktop form for manual entry with validation • Search, filter, and CSV/Excel export functions • Clear setup, backup, and maintenance documentation Acceptance criteria 1. I can install the solution on Windows or Linux using the instructions you provide. 2. Sample records enter, save, and retrieve without errors or duplication. 3. Exported data opens correctly in Excel or any CSV reader. Open-source stacks and clean, documented code are strongly preferred.
