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