## Preface

There are two different APIs that can be used to write Oracle NoSQL Database (Oracle NoSQL Database) applications: the original key/value API, and the tables API. This document describes how to write Oracle NoSQL Database applications using the tables API. Note that most application developers should use the tables API because it offers important features, including secondary indexes.

This document provides the concepts surrounding Oracle NoSQL Database, data schema considerations, as well as introductory programming examples.

This document is aimed at the software engineer responsible for writing an Oracle NoSQL Database application.

## Conventions Used in This Book

The following typographical conventions are used within in this manual:

Class names are represented in `monospaced font`, as are `method names`. For example: "The `KVStoreConfig()` constructor returns a `KVStoreConfig` class object."

Variable or non-literal text is presented in italics. For example: "Go to your KVHOME directory."

Program examples are displayed in a `monospaced font` on a shaded background. For example:

    import oracle.kv.KVStore;
    import oracle.kv.KVStoreConfig;

    ...

    KVStoreConfig kconfig = new KVStoreConfig("exampleStore",
        "node1.example.org:5088, node2.example.org:4129");
    KVStore kvstore = null;

In some situations, programming examples are updated from one chapter to the next. When this occurs, the new code is presented in `monospaced bold` font. For example:

    import oracle.kv.KVStore;
    import oracle.kv.KVStoreConfig;
    import oracle.kv.KVStoreFactory;

    ...

    KVStoreConfig kconfig = new KVStoreConfig("exampleStore",
        "node1.example.org:5088, node2.example.org:4129");
    KVStore kvstore = null;

    try {
        kvstore = KVStoreFactory.getStore(kconfig);
    } catch (FaultException fe) {
        // Some internal error occurred. Either abort your application
        // or retry the operation.
    }

### Note

Finally, notes of special interest are represented using a note block such as this.
