openfire 数据库

在学习openfire 之前，先简单的了解一下支撑它运行的数据模式，以后在学习过程中，可能要经常反复的学习数据模式，了解数据处理流程和存储过程必不少的环节的。

标准文档如下，原文连接：http://www./builds/openfire/docs/latest/documentation/database-guide.html

Introduction

This document outlines the data type conventions and tables in the Openfire database schema. Some information, like column indexes and foreign keys, is omitted. For this, please read the individual schema of the database you're interested in.

Data Type Conventions

Date column type support varies widely across databases. Therefore, Openfire specially encodes dates as VARCHAR values. Each date is a Java long value which is 0-padded to 15 characters. The long value is the internal representation of Java Date objects, which can be obtained with code such as the following:

long currentDate = new Date().getTime();

Boolean values are always represented a numeric values: 0 for false and 1 for true.
