19 * \brief Document for internal data structure of any object storage. Corresponds to the SALOME study.
20 * Document contains all data of te SALOME Study specific to this module
21 * that must be written into the HDF file.
22 * Also it provides acces to this data: open/save, transactions management etc.
23 * to provide access to all stored data.
