Create my contact database in Libre Office Base

I used to have a personal database in Microsoft Access 2000, which I used to track personal contacts, their organisations, their interests/topics, and my contacts with them. The interests feature of this will no longer work, apparently due to upgrades to Microsoft Windows. I want this database to be rebuilt in Libre Base, so that I can use it on any computer including Linux. Key features are shown in the attached Microsoft Access database: many to many relationships for individuals, organisations, interests and contacts. Sorry, having problems entering contact details and interests, so that does not work as before. Also, in deleting my personal data some things don't work as well. All features should work in the Base database file. Not necessary to use "DefaultOrg" or NonDefaultOrg. LastUpdated field should show when a record was modified.
