 # 介绍
 
 Linkis 在上层应用程序和底层引擎之间构建了一层计算中间件。通过使用 Linkis 提供的 REST/WebSocket/JDBC 等标准接口,
-上层应用可以方便地连接访问 MySQL/Spark/Hive/Presto/Flink 等底层引擎,同时实现变量、脚本、函数和资源文件等用户资源的跨上层应用互通。  
+上层应用可以方便地连接访问 MySQL/Spark/Hive/Presto/Flink 等底层引擎,同时实现变量、脚本、函数和资源文件等用户资源的跨上层应用互通。
 作为计算中间件,Linkis 提供了强大的连通、复用、编排、扩展和治理管控能力。通过计算中间件将应用层和引擎层解耦,简化了复杂的网络调用关系,
-降低了整体复杂度,同时节约了整体开发和维护成本。

 Linkis 自 2019 年开源发布以来,已累计积累了 700 多家试验企业和 1000+沙盒试验用户,涉及金融、电信、制造、互联网等多个行业。
 许多公司已经将 Linkis 作为大数据平台底层计算存储引擎的统一入口,和计算请求/任务的治理管控利器。
