关系型数据库(Relational Database,RDB)是一种基于关系模型来管理数据的数据库。关系型数据库基于SQLite组件提供了一套完整的对本地数据库进行管理的机制,对外提供了一系列的增、删、改、查等接口,也可以直接运行用户输入的SQL语句来满足复杂的场景需要。 该模块提供以下关系型数据库相关的常用功能: [RdbPredicates]:...
Is the solution an acid, a base, or neutral? Strong Base: A Bronsted base is a substance that undergoes a reversible protonation reaction when dissolved into aqueous solution. The Bronsted acid reactant here is the water molecule, so the two pr...
