Class TabularEtlManager

The TabularEtlManager class is used to manage the extraction and loading of tabular data. Implements the [Workspace.XBR.Xperiflow.Etl.Tabular.ITabularEtlManager](../Xperiflow.Etl.Tabular/ITabularEtlManager.md) interface.

Using a [Workspace.XBR.Xperiflow.Etl.Tabular.TabularEtlManager](../Xperiflow.Etl.Tabular/TabularEtlManager.md), you can extract data from a source and load it into a destination in separate steps, or with a call to ExtractAndLoad(). Use the XBRApi to instantiate an [Workspace.XBR.Xperiflow.Etl.Tabular.ITabularEtlManager](../Xperiflow.Etl.Tabular/ITabularEtlManager.md). For example:

Example:

` var etlManager = XBRApi.Etl.GetTabularEtlManager(si); `

Example:

` var dataReader = etlManager.ExtractDataReader(sourceData); `

Example:

` etlManager.Load(destinationData, dataReader) `

• OR more simply-

Example:

` etlManager.ExtractAndLoad(sourceDataDefinition, destinationDataDefinition); `

Namespace: Workspace.XBR.Xperiflow.Etl.Tabular
