Structure

This manual contains three chapters and three appendixes:

Chapter 1	Introduces RE Batch API.
Chapter 2	Describes the RE Batch API supporting classes.
Chapter 3	Describes the methods used to manage sessions, manage data, and request recommendations
Appendix A	Contains examples of how to perform common tasks with the RE Batch API.
Appendix B	Contains complete sample program.

Accessibility of Code Examples in Documentation

JAWS, a Windows screen reader, may not always correctly read the code examples in this document. The conventions for writing code require that closing braces should appear on an otherwise empty line; however, JAWS may not always read a line of text that consists solely of a bracket or brace.

Conventions

In this manual, Windows refers to the Windows 95, Windows 98, and the Windows NT operating systems.

The SQL interface to Oracle9i is referred to as SQL. This interface is the Oracle 9i implementation of the SQL standard ANSI X3.135-1992, ISO 9075:1992, commonly referred to as the ANSI/ISO SQL standard or SQL92.

In examples, an implied carriage return occurs at the end of each line, unless otherwise noted. You must press the Return key at the end of a line of input.

The following conventions are also used in this manual:

Convention	Meaning
. . .	Vertical ellipsis points in an example mean that information not directly related to the example has been omitted.
....	Horizontal ellipsis points in statements or commands mean that parts of the statement or command not directly related to the example have been omitted
boldface text	Boldface type in text indicates a term defined in the text, the glossary, or in both locations.
< >	Angle brackets enclose user-supplied names.
[ ]	Brackets enclose optional clauses from which you can choose one or none.
syntax text	Text in syntax font is used to describe the syntax of Java code.
italic text or syntax	Text or syntax in italics specify user-supplied names or data.
