New page

The data model of solvers is always arbitratry, sometimes proprietary and almost never generic.
In simantics environment, the data is exposed in the format of [[Databoard_Specification#Datasource_Contract|Datasource Contract]]
by implementing [[Databoard_dev#Accessors|Accessor Interface]]. It gives the access means to read, browse and monitor the data models.

The values of variables can be monitored in Simantics Workbench desktop client.
Values are followed in a property viewer component on the left-hand side of the workspace.
There are monitor objects on a diagram, that follow values of variables at real-time as the experiment progresses.
Charts visualizations draw the trends of the variables, from their collected samples, at real-time or after experiment.

An experiment may be recorded by collecting samples. A sampling may contain all values of all variables, a sub-set of values, and/or a sub-set of variables.
<tt>SamplingConfiguration</tt> defines how samples are collected from the variables during the experiment. The result is stored in the
format of [[Databoard_Specification#History_Contract|History Contract]].

==Use Cases==

===UC 1: Run an local experiment===
[[image:local_experiment.png|The dataflows in a local experiment]]

Experiment is executed locally in the Simantics Workbench application.
Experiment controller exposes two features: ''datasource'' and ''history''. See [[Task_protocol]] for more details.

The simulation time data is in [[Databoard_Specification#Datasource_Contract|Datasource Contract]] format.
Values are viewed in property viewer, monitors on diagram, and in a visualizing charts.

Experiment Controller also records the data into time series.
The format of the time series is defined in [[Databoard_Specification#History_Contract|History Contract]].
<tt>Subscripion Configuration</tt> desribes what variables are recorded and how sampled.

Chart configuration includes Expression Configuration.

===UC 2: Run a remote experiment===
[[image:remote_experiment.png|The dataflows in a remote experiment]]

Experiment is executed in a remote process called Task Manager.
The values are accessed using Wire protocol and cached in Simantics Workbench application.
Values are cached in memory before used by higher level UI components.
Partial Accessor implementation provides caching features.

===UC 3: Persist an experiment result===
[[image:archive.png|Put the experiment result into an archive]]

Experiment is persisted into a local archive. Local archive stores the experiment as files in the workspace folder of Simantics Workbench application.

Data structure of the archive is in [[Databoard_Specification#Repository_Contract|Repository Contract]] format.
Basicly, it consists of folders and values nodes. Value node contains a recording of an experiment.
The folder hierarchy of the archive is organized by the end user.
An experiment recording is stored in a single file. The file contains a single [[Databoard_Specification#History_Contract|Sampling]] value.

===UC 4: Visualize a recorded experiment===
[[image:visualize_archive.png|Visualize a persisted experiment]]

Chart component visualizes the data from a memory cache. It renders data only in [[Databoard_Specification#History_Contract|History Contract]] format.

Chart configuration is source neutral. Same configuration can be used to render both cached real-time data and stored history data.
