Common Conception of the Data Storage

The Data Storage in OpenSCADA initially built on different Data Bases and the Configuration File for the common, but interaction between these essences was not very clear also as managing the storage data between different storages.

So, in version 0.9.5 there was performed the storage unification what provides in whole for:

• direct storage and specifying the Generic Storage "*.*" as a combination of the Configuration File and the work Data Base;

• control for the data presence on different storages and providing for a function of managing-removing only data without the control object and from previous storages; priority of the DBs in their accessing;

• limiting of all configured-selected Data Bases only by the form "{Type}.{DB}" without a table here, that specified-bound to the object ID;

• all the data accessing functions moved under the conception.[подробнее]
