ICubeMetaExporter.ScaleValues

Syntax

ScaleValues: Boolean;

Description

The ScaleValues property determines whether data must be normalized on export.

Comments

When the False value is set, data of every factor is loaded with measurement unit scale specified for it. Therefore, the uploaded data is non-uniform. When the True value is set, exported data is normalized that is it is brought to one measurement unit scale.

Example

Executing the example requires a time series database with the OBJ_RUBRICATOR identifier. The database must include the COUNTRIES attribute.

Sub Main;

Var

TextConsumer: IDtTextConsumer;

MB: IMetabase;

Exporter: ICubeMetaExporter;

Binding: ICubeMetaExporterBinding;

Begin

// Data consumer for exporting to the textual format

TextConsumer := New DtTextConsumer.Create;

TextConsumer.File := "C:\result_meta_exp.txt";

TextConsumer.FormatType := DtTextFormatType.Delimited;

TextConsumer.DelimitedColumnDelimiter := ";";

TextConsumer.DelimitedTextQualifier := """";

TextConsumer.Encoding := "WIN";

TextConsumer.WriteHeader := True;

// Export parameters

Exporter := New CubeMetaExporterClass.Create;

MB := MetabaseClass.Active;

Exporter.Rubricator := MB.ItemById("OBJ_RUBRICATOR").Bind As IRubricator;

Exporter.Consumer := TextConsumer As IDtConsumer;

Exporter.ScaleValues := True;

// The COUNTRIES attribute binding

Binding := Exporter.Bindings.Add;

Binding.FieldName := "CountryKey";

Binding.DataType := DbDataType.Integer;

Binding.BindingType := CubeMetaExporterBindingType.Attribute;

Binding.Attribute := "COUNTRIES";

Binding.KeyField := "KEY";

// Calendar binding

Binding := Exporter.Bindings.Add;

Binding.FieldName := "Year";

Binding.DataType := DbDataType.String;

Binding.BindingType := CubeMetaExporterBindingType.Calendar;

Binding.DateFormat := "$Year$";

Binding.ValueFieldName := "Value";

Binding.ValueDataType := DbDataType.Float;

Exporter.ByColumns := False;

Exporter.CalendarLevel := DimCalendarLevel.Year;

// Export

Exporter.Export;

End Sub Main;

After executing the example factors are exported to the C:\result_meta_exp.txt file. Exported data is normalized.
