open
Prepares the database for use. An existing database is opened or otherwise an empty database is created.
If the database is openend a table _META with meta info is loaded into a dictionary _META. The dictionary key is the
code of the data element. A data element is either a tabel (dimension/event) or a field (characteristic/property).
The value of the dictionary is the MET_INFO structure. This structure contains meta data about the data element.
If the database is created an empty table _META is created.
The function calls virtual functions, db_, which must be overriden by a derived class for a specific database implementation.
