I do my DBs with Python and SQLite (doesn't require installing a DB manager, a SQLite DB is just a plain file).
There are also SQLite browsers/editors if you want to so everything by hand and many generic DB browser editors also support SQLite (in addition to MySQL, MariaDB, Oracle...). This can be useful elsewhere (Digikam, for instance, keeps its DB is a SQLite file.)
