The SEDRIS Data Representation Model
APPENDIX A - Classes Data Table |
|---|
An instance of this DRM class specifies an N-dimensional array of data cells, each of which has the same data signature, representing some environmental data. The general nature of the environmental data being represented is indicated by the required <Classification Data> component. The specific contents in the context of that <Classification Data> instance are given by the signature of the <Data Table> instance (i.e., the combination of its ordered <Axis> components and ordered <Table Property Description> components).
The N dimensions of a <Data Table> instance are specified by its N ordered <Axis> components.
The complete structure of a cell within a <Data Table> instance is described by the complete ordered set of <Table Property Description> components of that <Data Table> instance. This set is termed the data signature, and applies to all cells of the <Data Table> instance.
Additional information about any given cell property, where such information is to be applied throughout the scope of the <Data Table> instance (e.g., sentinel values and tolerances) is specified by attaching <Property Characteristic> components to the applicable <Table Property Description> instance(s).
See individual subclasses for examples.
See P4V6 of the SEDRIS Documentation Set for detailed information on <Data Table> instance manipulation.
The actual cells of a <Data Table> instance are hidden by the API implementation being used to provide the <Data Table> instance. See the SE_PutDataTableData() function in the level 0 API for <Data Table> instance production, and the level 0 function SE_GetDataTableData() for consumption.
The general nature of the data set in indicated by the required <Classification Data> component. The specific contents in the context of that <Classification Data> instance are given by the signature of the <Data Table> instance, that is, the combination of its ordered <Axis> and <Table Property Description> components.
Yes; see <Property Table>.
