IMDB (In Memory DB)

The IMDB manager (In Memory DB) of historicals allows data to be saved in text and xml format.

The Movicon historicals management can be executed through the IMDB manager which allows data to be saved in text and XML format. This functionality can be used as an interesting alternative to the using the ODBC Manager, to allow you to obtain historical archives in text format  (file ".dat"), in clear or crypted as well as XML format (file ".xml").  By doing this you  get the advantage of getting better performances by avoiding the 'layer' of ODBC software and the possibility to cript data in proprietor format, even if you give up using relational Databases formats.

The IMDB manager, with the exclusive Emerson technology, manages a memory buffer in which data is placed and then unloaded on file at fixed time intervals The unloading data on file time can be configured through the appropriate properties of the log engine (ie. Data Logger, Log).

All the data query functions are supported as if managed by a database manager. This function can be activated with a specific option in the historical log, data logger and in the db trace.  It is not possible to use this technology in the "Real Time DBMS"  as it wouldn't be necessary to use it in that context.

Data is recorded on text files with the ".dat" extension.  When the  project is started up, Movicon will create table in memory by loading data from these back-u' files. The files can also be saved in XML format.
