ClientDataSet represents an in-memory dataset. A client dataset can be used asA fully-functional, stand-alone, file-based dataset for single-tiered database applications. When used in this manner, the client dataset represents the data stored in a dedicated file on the user抯 hard disk. A local in-memory buffer of the records from another dataset. The other (source) dataset can reside in the same form or data module as the client dataset (for example, when the client dataset provides navigation and editing support for the data from a unidirectional dataset). The source dataset can also reside on a separate system when the client dataset supports the client portion of a multi-tiered database application.
