Preface

Oracle Call Interface (OCI) is an application programming interface (API) that lets applications written in C or C++ interact with Oracle Database. OCI gives your programs the capability to perform the full range of database operations that are possible with Oracle Database, including SQL statement processing and object manipulation.

Audience

This guide is intended for programmers developing new applications or converting existing applications to run in the Oracle Database environment. This comprehensive treatment of OCI is also valuable to systems analysts, project managers, and others interested in the development of database applications.

This guide assumes that you have a working knowledge of application programming using C. Readers should also be familiar with the use of structured query language (SQL) to access information in relational database systems. In addition, some sections of this guide assume knowledge of the basic concepts of object-oriented programming.
