Much of the data that is (or could be) presented on the Web already exists in electronic form. Not only can it be a challenge to create a website or Web application to present your data using conventional tools, accessing the data itself could be difficult. Some products rely on manually created or assistant-generated Structured Query Language (SQL) code, leading to database-specific code that is difficult to optimize. WebObjects avoids these problems by using Enterprise Objects, a model-based mechanism for cleanly instantiating business objects directly from database tables. Enterprise Objects handles all the interactions with the database including fetching, caching, and saving. This allows you to write your business logic against actual objects independent of the underlying data store. You can modify schemas, add or change databases, or even use a totally different storage mechanism without needing to rewrite your application.
JDBC is an interface between Java platforms and databases. WebObjects applications can access any database with a JDBC Type 2 or JDBC Type 4 driver.
