In this chapter, you learned how data is organized on the Palm OS and its devices. We showed you how to work with databases (creating, opening, and closing them). You learned how to deal with individual data records and how they interact with the databases in which they are stored. We described how to deal with records that are larger than 64K in size and how to handle secret records. We dealt with handling the sorting of databases, what methods to use in which circumstances, and how to handle a database with only one modified record.
You should now be able to create your own databases and records based on the Sales application source code.
