The dataset package is the entrypoint to the DataSet API, and includes the
major public classes for working with tabular
data in JDNC, including disconnected SQL results. The primary classes in this
package are DataSet
, DataTable
,
and DataSelector
. The DataSet API is described on
this webpage.
The major classes in this package--DataSet, DataTable, DataRelation, and others--all allow for an explicit name to be assigned, and are named automatically if no name is provided. Naming is a key concept as it allows one to work with different groupings of tables and their relations and to keep them conceptually separate.
