What can be found in the ODB

The Online Database contains specific system information related to the overall operation of the data acquisition and also to any information that the "MIDAS client" currently involved in the experiment wants to share across different Midas applications.

Accessing the ODB interactively

Accessing the MIDAS ODB interactively is done in two possible ways:

• Using the odbedit application command line.
• Using a web browser accessing the URL of the midas server

The ODB Structure

The data in the ODB are structured in a tree form with each "directory" dealing with a specific section of the acquisition. Particular system applications such as the Data Logger, Frontend will create on their initial ODB structure without user intervention. Later it will be possible for the user to modify these configurations to fit his requirements.
