## Preface

Welcome to Berkeley DB (DB). This document introduces DB, version 4.5. It is intended to provide a rapid introduction to the DB API set and related concepts. The goal of this document is to provide you with an efficient mechanism with which you can evaluate DB against your project's technical requirements. As such, this document is intended for Java developers and senior software architects who are looking for an in-process data management solution. No prior experience with Berkeley DB is expected or required.

## 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 `Database()` constructor returns a `Database` class object."

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

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

    import com.sleepycat.db.DatabaseConfig;

    ...

    // Allow the database to be created.
    DatabaseConfig myDbConfig = new DatabaseConfig();
    myDbConfig.setAllowCreate(true);

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 com.sleepycat.db.Database;
    import com.sleepycat.db.DatabaseConfig;

    ...

    // Allow the database to be created.
    DatabaseConfig myDbConfig = new DatabaseConfig();
    myDbConfig.setAllowCreate(true);
    Database myDb = new Database("mydb.db", null, myDbConfig);

### Note

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