If you want to write an application that accesses a database, you'll need to use Enterprise Objects in conjunction with WebObjects. And although database access is covered in the tutorials in Getting Started With WebObjects, you'll probably also want to read the Enterprise Objects Framework Developer's Guide for more in-depth information.
