## Preface

This document describes how to write replicated applications for Berkeley DB 18 Release 18.1 (library version 18.1.40). The APIs used to implement replication in your application are described here. This book describes the concepts surrounding replication, the scenarios under which you might choose to use it, and the architectural requirements that a replication application has over a transactional application.

This book is aimed at the software engineer responsible for writing a replicated DB application.

This book assumes that you have already read and understood the concepts contained in the Berkeley DB Getting Started with Transaction Processing guide.

## 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: "`DbEnv::open()` is a `DbEnv` class method."

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:

    typedef struct vendor {
        char name[MAXFIELD];             // Vendor name
        char street[MAXFIELD];           // Street name and number
        char city[MAXFIELD];             // City
        char state[3];                   // Two-digit US state code
        char zipcode[6];                 // US zipcode
        char phone_number[13];           // Vendor phone number
    } VENDOR;

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:

    typedef struct vendor {
        char name[MAXFIELD];             // Vendor name
        char street[MAXFIELD];           // Street name and number
        char city[MAXFIELD];             // City
        char state[3];                   // Two-digit US state code
        char zipcode[6];                 // US zipcode
        char phone_number[13];           // Vendor phone number
        char sales_rep[MAXFIELD];        // Name of sales representative
        char sales_rep_phone[MAXFIELD];  // Sales rep's phone number
    } VENDOR;
