Priodata 查询计划是最常用的 V$ 视图的前端，用于调查 Oracle 数据库中的 SQL 执行性能。您可以浏览共享光标区域以查找低性能 SQL，查看所有相关信息（取自 V$SQL 视图）和完整的 SQL 语句及其执行计划（取自 V$SQL_PLAN）。此外，还可以从优化器统计信息（last_analyzed和num_rows）中捕获信息，并结合执行计划放置，从而改进分析。所有这一切都与一个精细的图形界面，而无需编写自己的查询和联接。查询计划确实提高了调整 Oracle 应用程序的过程的性能。此产品非常适合顾问、DBA 和应用程序开发人员，因为它可自动执行一些必须写入的查询，以便对数据库进行正确的调整。虽然该产品很简单，但与其他高功能的 Oracle 工具相比，它具有创新性，价格非常低。兼容 Oracle 9i 及更晚版本。
