Hello! I'd be happy to help you with your question about databases. Based on your description, it sounds like you are looking for a DBMS (Database Management System) that is user-friendly and can be quickly learned within a few days. One option that fits this criteria is Microsoft Access.
Microsoft Access is a relational database management system that is part of the Microsoft Office suite. It is designed to be user-friendly and is often used by non-programmers for creating databases. With Microsoft Access, you can create forms similar to Google Forms for data entry, and you can easily export the data to an Excel file.
To achieve the setup you described where each person has their own section in the database that can be accessed by anyone, you can create a table in Access with fields for each person's information. You can then create forms for data entry and set up queries to filter and display information based on the person selected.
Within 2-3 days, you can familiarize yourself with the basics of Microsoft Access, including creating tables, forms, and queries. There are also many online tutorials and resources available to help you learn how to use Access effectively.
I hope this helps! Let me know if you have any more questions or need further assistance.
