1. 弹性搜索：
它是一个分布式搜索和分析引擎。它是开源的，可以用于所有类型的数据。它是用Java编程语言实现的，支持所有具有Java虚拟机(JVM)的操作系统。它是Elastic的主要组件Stack，这是一个用于数据分析和可视化的开源应用程序。它具有很高的可扩展性，执行动作的速度也很高，这使其成为数据分析、处理和可视化的简单快捷的工具。
2. SQLite：
它是一个关系数据库管理系统，在系统正常运行所需的设置、管理和资源方面重量轻。它是服务器少，因此不需要服务器运行命令。 SQLite 是一个开源库，因此它可以免费用于私人和商业用途。 SQLite 可以进行多任务处理以同时进行读取和写入。它支持 ACID 属性，确保可靠的事务处理。
