You can certainly have multiple 'songs' from the one pdf without having to split it first and there are a few ways of doing it. For example you could create a song that is the whole pdf then go through it creating individual songs using the 'create snippet' function, or you could create each song by importing the pdf each time (after the first time the app will ask you whether you want to use the original pdf or actually re-import it and you can just select the option to use the original pdf), or you can populate a spreadsheet with the details of each song in the pdf (page numbers, title, composer etc) and then import the pdf with the spreadsheet/csv file - the app will then create all the songs in one go according to the date in the spreadsheet/csv file. Have you had a chance to look at the manual? That has details on all these methods and others too. I think it also has info on how to unhide the database if you want to do that to back it up, although the app has its own options for backup which might be more useful.
