The Newton operating system supplies a suite of objects that interact with each
other to provide data storage and retrieval services. This chapter describes the use
of these objects--stores, soups, cursors, and entries--to save and retrieve data. If
you are developing an application that saves data, retrieves data, or provides
preexisting data, you should familiarize yourself with the contents of this chapter.
