Parameter Database and Web Interface Tools Why not the present simple solution? 1.Easy for you but time consuming (and boring) for me as administrator. 2.Expect the number of parameter to increase. 3.Minimize sources of errors.

The Database Structure Reference Id Title Author Publication URL Data Team_ID System_ID Attribute_ID Parameter_ID Validator_ID Value Status Date_modified Comment Team Id Parent_Id Name Manager_Id System Id Parent_id Name Validator Id Name Manager Id Name Parameter Id Name Unit_id Definition Date_modified Reference_id Unit Id Name Attribute Id Name

Team or role, or view, or category… Natural to categorize parameters by teams, since the parameter list is a communication tool. Replaces the current tables names. Each team has a parameter manager (owner), with privileges to administrate parameters in the database. One person can be manager over several teams. Hierarchal structure

Example

Attribute Default is nominal but can also be approximate, maximum, minimum, precision, accuracy... Optional Used for example by the planned Parameter Book. (application)

Parameter The Parameter table accounts for the definition of parameters and unit. The level of unit control needs to be defined. To the lowest level it will be enforced that all parameters with identical name shall also have the same unit.

Data The primary key of the Data table is a tuple of System, Attribute and Parameter. Each record in the Data table will therefore be uniquely identified through this relation. A parameter name can apply to several systems of the facility.

Validation As before in boards (CCB, Technical board) Default validator is parent team Can however be someone else, for example for “interfaces” (target window, power coupler, etc.) between different groups.

Web Interface Tools Java based web interface tools. (Versatile, self-explanatory and efficient). A certain amount of control needs to be established, for example, for units and user privileges. This should be kept to a minimum. Example: Editor, tools to keep track of dependencies, Queries, Parameter Book.
