Group data store

Group data store is a second data source that made from original data source (database, UDS, file/HTTP store, XML DTD store) and split into multiple datasets.

Group data store derives multiple datasets from one dataset, so it takes advantages of requesting smaller queries and data transmissions than multiple independent dataset.

For example, It would be better that create one dataset from one query and split into three datasets using group data store than creating three datasets from three queries.

Original dataset

The dataset from which multiple datasets are derived. When split a master/detail dataset, only the top level master dataset can be the original dataset.

Group dataset

The datasets derived from the original dataset. The group datasets can be used the same as normal dataset.
