UnityJDBC 驱动程序可以在单个 SQL 查询中集成和查询任意数量的 JDBC 可访问数据源（包括 Oracle、SQL Server、MySQL 和 Postgres）。UnityJDBC 包含一个内置的数据库引擎和优化器，可与集成系统分开使用。UnityJDBC 会自动翻译 SQL 函数和方言，并在从一个数据库系统转换为另一个数据库系统时使用。 特征： 集成所有内容：UnityJDBC 允许您编写单个 SQL 查询，以从任意数量的 JDBC 可访问数据源中提取数据。查询可以联接或匹配源之间的数据，并返回单个 ResultSet。 最高性能：UnityJDBC 的开销最小，并且包含一种独特的联接算法，它返回的结果速度比以前的算法快。内置优化器重组查询以创建最有效的执行计划。 它可以处理大于主内存的查询。 基于标准：UnityJDBC 是纯 Java，可用于任何支持 Java 的平台（Windows、Linux、UNIX）。系统支持标准 SQL 查询，与其他 JDBC 驱动程序完全一样工作。这允许快速开发访问多个数据库的应用程序，而无需新的中间件软件或培训程序员在不同的开发环境中。 它可以部署在应用程序和 Web 服务器以及独立的 Java 应用程序中。 数据库注释：系统允许开发人员重命名正在查询的数据库中的字段和表。这样可以更轻松地跟踪和查询数据库。 匹配和合并数据：MERGE 运算符允许超出标准联接的查询并跟踪数据来源。 函数转换：UnityJDBC 支持所有标准 SQL 函数、用户定义的函数，并翻译特定于每个数据库系统方言和支持级别的函数，包括日期/时间函数、字符串操作和 LIMIT/OFFSET 分页。
