Preface Oracle Database Advanced Application Developer's Guide explains topics that experienced application developers reference repeatedly. Information in this guide applies to features that work the same on all supported platforms, and does not include system-specific information. Preface topics: ■ Audience ■ Documentation Accessibility ■ Related Documents ■ Conventions Audience Oracle Database Advanced Application Developer's Guide is intended for application developers who are either developing applications or converting applications to run in the Oracle Database environment. This guide is also valuable to anyone who is interested in the development of database applications, such as systems analysts and project managers. To use this document effectively, you need a working knowledge of: ■ Application programming ■ Structured Query Language (SQL) ■ Object-oriented programming Documentation Accessibility 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.
