This document describes the features of Oracle Database for Windows software installed on Windows 2003, Windows 2000, and Windows XP Professional operating systems.
This guide describes Oracle Database Extensions for .NET, which provides a Common Language Runtime (CLR) host for Oracle Database and data access through Oracle Data Provider for .NET (ODP.NET) classes.
This preface contains these topics:
Oracle Database Extensions for .NET Developer's Guide is intended for programmers who are developing applications to access an Oracle Database using Oracle Database Extensions for .NET. This documentation is also valuable to systems analysts, project managers, and others interested in the development of database applications.
To use this document, you must be familiar with Microsoft .NET Framework classes and ADO.NET and have a working knowledge of application programming using Microsoft C#, Visual Basic, or another .NET language.
Users should also be familiar with the use of Structured Query Language (SQL) to access information in relational database systems.
Our goal is to make Oracle products, services, and supporting documentation accessible to all users, including users that are disabled. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.
