You can transform data from one location(source) to another(destination) with adding modification to the data using Data Flow Tasks..To Create a Data Flow you need to select the Data Flow Task from the control flow panel and add to the control panel tab and double click on it . chose the appropriate Data Source and the Data Destination for the data transformation.
Data Source Can Be
* Data Reader Source – Extract data from relational DB by using .Net Provider
* Excel Source – Extract data from excel work book
* Flat File Source - Extract data from flat files
* OLE DB Source - – Extract data from relational DB by using OLE DB connection
Data Destination Can be
* Data Mining Model Training
* Data Reader Destination
* Dimension Processing
* Excel Destination
* Flat File Destination
* OLE DB Destination
I am going to discuss on OLE DB Source to OLE DB data transformation.
First drag and drop the OLE DB Source task and rename the name and description
Double Click the Task –
Select the OLE DB Connection Manager
Data Access Mode
Data Excrating Source – Which can be SQL command,Table/Veiw according to the data access mode you select
Always preview the table before closing the tab in order to avoid errors at the execution state
Then Drag and drop OLE DB Destination task and name it appropraiately
Before you do your mapping you should connect the Source and the destination first
For that you can just connect two task using OLE DB Source output(select both two packages right click -> add path-> OLE DB Source output)
Or
You can put any Data Flow Transformation task and then connect
Data Flow Transformation Tasks are show in the picture, you can use any of these task in-between and map to the destination
After mapping the source with the destination you can double click the Destination task and select the appropriate destination table from the connection manager and arrange the mapping accordingly
This is a great post about Data Flow Task. We all know how crucial data is for a business growth and web data mining is serving this purpose
