Transferring Files to the S3 storage service

Once you establish a connection to the Amazon S3 storage service, you can proceed to configure the data source in Sigma Studio for transferring the files to the listed Amazon S3 cloud-based storage service. 

For transferring the files to the S3 cloud-based storage service using Sigma Studio, perform the following steps:

1. Right-click the created Amazon S3 connection and select the Create Data Source option.
   
   Refer Connectors - Amazon S3 for more information on creating an Amazon S3 connection.
   
   
   
   The Create New Data Source page appears.
   
   
   
   
2. Enter a unique data source name in the Data Source Name field, e.g. AMAZON S3 DS.
   
   
   
   

3. If you want to fetch a particular file from the S3 cloud-based storage service, specify the relevant file path and the accurate file name in the File Path and File Name fields respectively.
   

   For transferring the files to the S3 cloud-based storage service, there is no need to specify the file path and the file name. Only to receive or fetch files from the S3 cloud-based storage service, you must specify the relevant file path and the accurate file name.

   
   
   
   
   

4. In the Bucket Name field, provide the bucket name present in the connected S3 storage service, e.g. barathbucket23456.
   

   The Local File Path and File Name are optional fields. Both the Local File Path and File Name fields are not required to create a FTP DS, with the Put File Request Type. It is sufficient only if you provide the appropriate server path in the Relative Path on Server field. You can receive files of following formats from the FTP server:

   • CSV
   • XLS
   • PDF
   • DOCX
   • TXT
   • HTML
   • XML

   
   
   

5. Click Save to save the FTP data source.
   

   When you try to exit the Data Source screen, before saving the configured FTP data source, a warning pop-up message appears, as shown in the following screen shot:
   

   • Click Cancel, if you do not want to exit the Data Source screen.
   • Click Ok, if you want to exit the Data Source screen.

   
   
   
   A success message for creating the data source appears as shown in the following screenshot:
   
   
   
   

6. Click Ok.

   In order to trigger the FTP service connection, the CT platform's server-side API, CT.ftp must be used while passing the ExecutionContext action in a Java Handler class. Refer the following sample code snippet for better understanding on the triggering process:

   Here, on the following sample code snippet a new ExecutionContext action is created within which a map (HashMap) is built. The FTP datasource ID is passed as the input to activate the connection request within which the CT.ftp API is passed to trigger the process.

   ExecutionContext ec = new ExecutionContext();
   	Map inputParams1 = new HashMap();
   	inputParams1.put("DATA_SRC_ID","FTP_DS");  // FTP_DS refers to the Datasource ID.
   	ec.setInitialRequestData(inputParams1);
   	try {
   		CT.ftp(ec);
   	}
   	catch(Exception e){	
   	}

Client Customization

To customize a FTP data source for a specific corporate client or customer, perform the following steps in Sigma Studio:

1. Right-click the newly created FTP data source (e.g. FTP_DS) and select the Customize DS for Client option.
   
   
   
   The Edit Datasource page appears.
   
   
   
   

2.  Click the Client lookup field and select the Corporate Client or Customer of your choice, e.g. HIGHSCORE.

   The Parent Data Source Id and Connection Name are non-editable fields.  icon is used to export the FTP data source in the SQL format, while  is used to delete the FTP data source.

   
   
   
   

3.  Provide a unique data source name in the Data Source Name field, e.g. HIGHSCORE FTP DS.
   
   1. Select the Put File option in Request Type to send the requested file to the FTP server.

   2. Provide the appropriate file path on the FTP server to which the files need to be transferred to the server in the Relative Path on Server field.

      The Local File Path and File Name are optional fields. Both the Local File Path and File Name fields are not required to create a FTP DS, with the Put File Request Type. It is sufficient only if you provide the appropriate server path, specific to the selected corporate client or customer, in the Relative Path on Server field.

      
      
      

4. Click Save to save the customized FTP data source for the selected HIGHSCORE client.
   
   
   
   A confirmation message, indicating a successful save of the customized FTP data source, appears.
   
   
   
   
5. Click Ok.

6. Access the Information Report screen and configure the report with the relevant and appropriate configurations, as shown in the following screen shot:

   For detailed information on creating reports, refer Configuring Reports.

   
   
   
   

7. Click the Additional Info tab.
   
   
   
   

8. Click the Publishers drop-down list and select the FTP option.

   
   
   

9. Click the Publisher Data Source lookup field and select the relevant FTP data source, e.g. FTP_DS. 

   For making use of the the customized data source for a specific client, it is essential that the Parent FTP data source for the customized client data source should be aptly selected. The customized client FTP data source is HIGHSCORE FTP DS, whereas the Parent Data Source Id is FTP_DS. So, it is essential that the FTP_DS Parent Data Source is selected in the Publisher Data Source lookup field, while configuring a report in Sigma Studio.

   
   
   
   

10. Once the report is configured with essential attributes, click Save to save the report.
    
     
    
    

11. Access the relevant report, e.g. HIGHSCORE REPORT in the Sigma Application and click Run to generate the report.

    For detailed information on generating the reports in Sigma Application, refer Generating a Report in Sigma. Once the report gets generated, the generated report can be found in the relevant server path, which was specified as the relative server path, while configuring the FTP data source in Sigma Studio.

     
    

    
    
    The HIGHSCORE REPORT XLS file can be found in the provided FTP server path or the Relative Server Path (e.g. /workfolder/files/), as shown in the following screen shot:
