Description

Use TCustomDataStore as a base class when defining classes that fetch data from appropriately structured datasets and analyze it into a multidimensional array of summary values. Each dimension corresponds to a field in the dataset over which information is summarized. TCustomDataStore maintains a cached projection of this array over a set of active dimensions. The cache allows TCustomDataStore to quickly provide a projection of any subset of the active dimensions. 

TCustomDataStore introduces properties and methods that describe the dimensions of the crosstabulated data array and the summary values that are computed over those dimensions. 

Do not create instances of TCustomDataStore. To make the crosstabulated data from a TCustomDataStore object available to the objects in a form, use a TDecisionCube object.
