The central participant database (CPDB) keeps participants in one place for all your surveys. You add a person once, with their attributes, and copy them into the participant list of any survey. It also keeps a blocklist, so people who don't want your surveys are not invited again. For a single survey you don't need it: create the participant list in the survey. See Create a participant list.
Click Configuration > Users > Central participant management in the top bar.
In the picture: 1 the buttons Display CPDB participants, Summary, Import, Blocklist settings, Attributes, Share panel and Export all participants, 2 Add participant, 3 Blocklisted, 4 the ... menu of a participant.

Attributes are extra fields, for example a department or a customer number. Click Attributes and Add new attribute, and choose the Attribute type: Text box, Drop-down list or Date. email, firstname and lastname are core attributes and always exist.
Note: The Survey list starts with the first survey of your site, not with the one you work on. Check it before you click Add.
List active surveys in the ... menu shows the surveys a participant is in.
Share this participant in the ... menu, or Share in the bar, gives other administrators access to participants you own. Share panel lists what you have shared, with whom, and whether they can edit.

No. A participant list belongs to one survey. The central database is shared by all your surveys, and you copy people from it into participant lists.
