推荐答案

该声明是正确的。 TADODataset和TADOCommand是与原生ADO对象的直接接口，并且可以执行其他三个所做的所有任务，这些任务存在以便于为BDE（Borland数据库引擎）编写的应用程序的移植应用程序，这意味着类似的接口 - 最终调用前两个。

That statement is correct. TADODataset and TADOCommand are direct interfaces to the native ADO objects, and can perform all the task made by the other three, which exist to ease porting application written for the BDE (Borland Database Engine), implmenting a similar interface - they end up calling the first two.
