Memento is a database product, and a user's Memento libraries, together with associated files — including photos, barcodes, and so on — constitute the user's overall Memento database. However, this is NOT a carefully defined term. One could consider the set of libraries within a Group to be a database; or perhaps each set of libraries that are linked together to formulate a solution, aggregated or otherwise. So, database remains a general term.
The set of all libraries in a database can be subdivided into Groups. Groups simplify lists of libraries. They are merely containers; there is no Group functionality.
The initial set of fields for a library is on a tab called MAIN; this is the name of a Page. The user can add more pages; each will have a name and a tab; and each will have its own set of fields. Each entry in a library contains all fields across all pages.
