Interface ITabularEtlManager

Defines a contract for managing the extraction and loading of tabular data.

Using an Workspace.XBR.Xperiflow.Etl.Tabular.ITabularEtlManager, 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 a Workspace.XBR.Xperiflow.Etl.Tabular.ITabularEtlManager. 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

Assembly: Xperiflow.dll

Declaration

public interface ITabularEtlManager

Load(DataDefinition, DataTable)

Writes data from a DataTable to a destination Workspace.XBR.Xperiflow.Etl.DataDefinition, for example:

Example:

` etlManager.Load(destinationDataDefinition, dt); `

Declaration

void Load(DataDefinition destinationDataDefinition, DataTable dt)

Parameters

Type	Name	Description

Example:

` etlManager.Load(destinationDataDefinition, reader); `

Declaration

void Load(DataDefinition destinationDataDefinition, IDataReader reader)

Parameters

Load(string, DataTable)

Writes data from a DataTable to a JSON serialized destination Workspace.XBR.Xperiflow.Etl.DataDefinition, for example:

Example:

` etlManager.Load(destinationJSON, dt); `

Declaration

void Load(string destinationDataDefinition, DataTable dt)

Parameters

ExtractAndLoad(DataDefinition, DataDefinition)

Extracts data from a source Workspace.XBR.Xperiflow.Etl.DataDefinition and loads it into a destination Workspace.XBR.Xperiflow.Etl.DataDefinition, for example:

Example:

` etlManager.ExtractAndLoad(sourceDataDefinition, destinationDataDefinition); `

Declaration

void ExtractAndLoad(DataDefinition sourceDataDefinition, DataDefinition destinationDataDefinition)

Remarks

Note: This method does not support loading from and extracting to JSON serialized Workspace.XBR.Xperiflow.Etl.DataDefinitions. However, if you have JSON serialized Workspace.XBR.Xperiflow.Etl.DataDefinitions, you can instantiate Workspace.XBR.Xperiflow.Etl.DataDefinition objects using Workspace.XBR.Xperiflow.Etl.DataDefinition

Parameters

Type	Name	Description
Workspace.XBR.Xperiflow.Etl.DataDefinition	sourceDataDefinition	The Workspace.XBR.Xperiflow.Etl.DataDefinition object to extract data from
