Versions of the Library Application

There are two versions of the Library application available for you to play with – the classic version (LibraryClassic.bsv) and the modern version (Library.bsv). Both versions have the same business objects and rules, but the user interface of the modern version is more contemporary. This document describes the classic version, so if you want to follow the document you should load LibraryClassic.bsv.

Once you are comfortable with the classic version you can load the modern version and check out the differences in the User Interface. The main difference is that queries on items and members that used to return a grid of items or members have been replaced in favour of custom queries that rely more heavily on HTML and CSS. Consequently many operations that used to be invoked from forms (such as borrowing an item) are called from custom queries using Javascript in the modern version.
