1. Introduction
Visual BSF ™ (VBSF) is an all Java object-relational framework that enables programmers to easily create fully scalable business classes that are persistent to relational databases. Scalable business object classes can be deployed in local (client-server) or distributed (3-tier) configurations with no modifications to source code. VBSF is made up of two components: a GUI based mapping tool and a supporting core library that provides the runtime services of the persistence layer. This guide explains the persistence layer API. For a complete reference of the classes in the persistence layer see the API Reference. For information on how to use the mapping tool see the Mapping Tool Guide.
The following type conventions are used throughout this guide:
| Type Conventions | |
|---|---|
| Type | Used for |
| Courier font in dark blue | Java code, Java class & attribute names, and directory & file names. |
| Italic | Database table and column names, or to emphasize text. |
Note: The terms business class and persistent class are used
interchangeably throughout this guide and the API Reference to refer to the same concept.
