The database describes several types of main objects: songs and books. They are associated with other objects: collectors, interpreters and places of collection.




In addition, for any textual search:

• The search is done by character string in the strict sense (replies to "guerre 1914" are not those of "1914 guerre").
• It is possible to use a truncation (*) to replace a letter, word, or group of words.
• It is not possible to search with Boolean operators of the type AND, OR, EXCEPT.
