It gets the dataset identified by the given name using the set of objects identification. A dataset can be connected or disconnected. A connected dataset, after its creation through the data source transactor, continues to depend on the connection given by its associated data source. Differently, a disconnected dataset, after its creation, no more depends of the connection given by the data source, and it continues to live after the connection has been released to the data source.

It executes a query that may return some data using a generic query. A dataset can be connected or disconnected. A connected dataset, after its creation through the data source transactor, continues to depend on the connection given by its associated data source. Differently, a disconnected dataset, after its creation, no more depends of the connection given by the data source, and it continues to live after the connection has been released to the data source. This method is different of the method that accepts a dataset name and a spatial filter, because it allows the retrieving of only a subset of the attributes, since a query can include a property list.
