Manage Data Imports

This article is currently being updated. Please come back later for updates.

Files can be imported into elluminate either through the Data Source and Import Definition process or by selecting a file and importing it manually. The Manual File Import process allows you to select the file and run the import on demand.

elluminate can import the following types of files: Excel, SAS Datasets, Text, CSV, XPT, and zipped.


Note: Files zipped with Deflate64 are not supported.

When importing data into a Global Data Store, you are limited to using FTP, Amazon S3, Box, and Nurocor MDR data sources, as well as manual file imports.

Note: A data store for Operational data (Operational Data Repository / Operational Oversight app) must be created prior to importing operational data.
When importing Operational Data Repository custom fields, data must be imported via an Excel file.

Note: When importing data, if a column is determined to contain Unicode, it is created as nVarchar. nVarchar columns support up to 4000 characters; therefore, a value greater than 4000 characters will be trimmed down to 4000 characters.

Note: When Study Import Control is enabled for a study and the import exceeds the defined threshold for the number of records with changes within the imported dataset, the import will complete with a warning notifying you that the change in the imported file is greater than what is allowed and has not been imported.

Run a Manual File Import

  1. Click the 9-dot icon to open the Platform Menu.
  2. By default, the Studies tab is selected at the top of the window. If importing to a global data store, click the Global Data Stores tab.
  3. Select Importer under Study Management or Global Data Stores Management from the left side of the Platform Menu.
  4. Select the Study / Global Data Store from the list on the right side of the Platform Menu. The Imports window opens.

    Importer_01.png

  5. Click the Manual File Import button. This opens a window where you select your file.

    Importer_02.png

  6. Check the Integrate Automatically box if you want the imported data to be integrated after the import is complete. If this is not checked, the data will be listed as 'Ready to integrate.'
  7. If the Integrate Automatically box is checked, check the Integrate Upon Discrepancies to integrate imported data even when discrepancies are found. If unchecked, data with discrepancies will generate an error.
  8. Check the Skip Mapping box to skip running any mappings on imported data. For example, a user may choose to skip mapping if using a global data store with many studies.
  9. Check the Defer Mapping box to defer the mapping, perhaps until the last import. For example, there are multiple imports in the same study, and you defer the mapping until the last import.
  10. Check the Skip Publishing box to skip publishing imported data for visualizations.
    Please be wary of using the Skip Mapping and Skip Publishing features. Although they will speed up an import, they can also have an effect on Analytics and other elluminate tools. Also, if mappings are not skipped or deferred, the import will pick up any mappings that had previously been deferred from manual imports.
  11. Select the Target Data Store from the drop-down. This is the Data Store into which the data should be imported.
  12. Select the file type from the File Type drop-down. This is not required if your file has the proper extension.

    Tip: When importing an Excel spreadsheet, the Importer scans the first 10 rows to automatically identify the row with column headers. This streamlines the process of handling custom-formatted sheets, eliminating the need for a manual import definition in many cases. If automatic detection fails, users can still make use of the import definition feature to specify the layout.

  13. Click Select File to search for the file you want to import. You can either browse for the file or drag and drop it to the window. Selecting the file automatically adds it to the bottom half of the imports window, where the data is ready to be imported and integrated.

    Importer_03.png

  14. You can add another file to this import using the Add File tab in the bottom half of the window.  This will add a file to the active import. You cannot add an additional file by clicking on Manual File Import.  This would create a new active import; you can only have one active import at a time.  
  15. If you add another file, it cannot have the same domain name; each file you import within the same active import must have a different domain name or different Excel tab name.
  16. Use the Import? column to select which domains you want to be integrated into elluminate. By default, all domains are selected.

  17. The Status column identifies whether your domain has any issues, whether it is okay or ready to integrate, or whether it is a new domain that has not previously been added to this study.

  18. Click the Integrate button in the top right of the bottom half of the window to begin the integration process. A confirmation window opens asking if you are sure you want to integrate.
  19. Click Yes to proceed with the integration of the data, or click No.

    If you click yes, the integration begins, and the data is integrated into elluminate. The status of the import will be displayed on the bottom half of the Imports window. Click the plus sign next to a domain to see the file. The bottom half of the window always displays the last import completed.

    Importer_04.png

Tip: If an import is already running when another import is started, the conflicting import will be queued until the current import is completed.

Create a New Import Definition

After a data source has been defined, a new import definition can be created. The definition details include information such as the name of the import, the data source, staging area, file, and header information. This then resides in the list of Imports and is there for future imports without having to make any of these selections again. Any previously created import definition details can be viewed in the top half of the Imports window. Typically, Import Definitions are scheduled to run at set times.

Note: For details, see the Configure and Manage Data Sources article in the Data Sources section.

Note: A data source is not necessary when making a Manual File Import.

  1. From the Imports window, click New or New from Template at the right of the imports window.  To see the available templates, click the drop-down arrow and select Templates from the list.
    1. If you select New from Template, the Select Template window opens.
    2. Select the template you wish to use and click Select.

      SelectTemplate.png

  2. The Import Definition Details window opens. Enter the name of the Import Definition in the Name field. This is a required field. If you created the import definition from a Template, all details from the template will be filled in, except the Name field.

    Note: The tabs across the top will include Import Definition and may include Options, Data Source Details, and / or Data Source based on the selected Data Source Type. Fields within each tab will also vary based on the selected Data Source.

  1. Click Save.

Important: Although you have created the data source and specified the Import Definition Details, the import will not occur unless scheduled or run manually.

Run an Import From a Defined Definition

Select Run to run an import for a currently defined import definition. These are the items listed on the Imports window. You may have these scheduled to run at set times, but if you want to pull in data before a scheduled import, you can select the import definition and click Run.

  1. Click the 9-dot icon to open the Platform Menu, then select Importer under Study Management.
  2. Select the study from the studies listed on the right side of the Platform Menu.
  3. From the study-level Imports window, select a defined import definition by clicking on a row. The row becomes highlighted blue.

    Importer_05.png

  4. Click the Run button. A Run Import confirmation window opens. Depending on the type of import, you may or may not see the additional checkboxes.

    Importer_06.png

  5. Click Integrate Automatically to integrate the data into elluminate. Remember that data are not available until they have been integrated into elluminate.
  6. If the Integrate Automatically box is checked, check the Integrate Upon Discrepancies to integrate imported data even when discrepancies are found. If unchecked, data with discrepancies will generate an error.
  7. If the study has configured the 'Enable Changed Data Records Threshold,' the Skip Data Change Threshold Check option will allow files to import that are over the threshold percentage without requiring the study to alter its configuration.
  8. Check the Defer Mapping box to defer the mapping, perhaps until the last import. For example, multiple imports are in the same study, and you defer the mapping until the last import.
  9. Check the Skip Mapping box to skip running any mappings on imported data. For example, a user may choose to skip mapping if using a global data store with many studies.
  10. Check the Skip Publishing box to skip publishing imported data for visualizations.
    Please be wary of using the Skip Mapping and Skip Publishing features. Although they will speed up an import, they can have an effect on Analytics and other elluminate tools. Also, if mappings are not skipped or deferred, the import will pick up any mappings that had previously been deferred from manual imports.
  11. Click Yes to proceed or No to cancel.
    If you click Yes, the import begins, and the results will display in the bottom half of the window. The Status field in the top left corner tells you the status of the import, whether it was successful, or if there was an error.

Tip: If an import is already running when another import is started, the conflicting import will be queued until the current import is completed.

Schedule an Import from a Defined Definition

By selecting Schedule, you can schedule the import to run automatically at any time and at any frequency you choose.  This can be done right from the Importer tab using the Schedule button, or you can schedule or manage this schedule using Tasks. 

Note: Each study can have an import scheduled to one data store at a time. For example, Study_A can be scheduled to import to its Clinical Staging Area at the same time that Study_B imports into its Clinical Staging Area, but Study_A cannot schedule two imports into its Clinical Staging Area to occur at the same time.

  1. From the study-level Importer window, select a defined import definition by clicking on a row. The row becomes highlighted blue.
  2. Click the Schedule button.
  3. A New Task window opens with 3 tabs: Task, Schedule, and Actions.
  4. From the Task tab, the Name field defaults to a combination of 'Import,' the Study name, and the import definition. To be more descriptive, change it as needed.
  5. In the Description field, enter any additional description for the schedule.
  6. The Active checkbox is selected by default. Clear the checkbox if you do not want the schedule to run.
  7. Click the Schedule tab.
  8. Select the timing of the import. Use the calendar and clock icons to select the times.
  9. Check the Repeat checkbox and add the Repeat every detail.
  10. Check the Ends checkbox and use the calendar icon to select the end date.
  11. Click the Actions tab.
  12. Because you are scheduling this from within Importer, the actions for this have already been defined – an Import and an email; the email, by default, is set to notify you when the import has been completed.

    Tip: You can edit the information in either the import or the email by clicking on the appropriate row’s Edit Action icon. For example, you may wish to change the name of the import. You may wish to add others to the email notification. You may only want to be notified if there was an error in the import.

  13. If you are satisfied with your selections, click Save. A Task for the scheduled import is created. 

Access and View Files from an Import

View Files in Importer

    Importer_07.png

  2. Click the Download icon to download the file to your computer.
  3. Click on the Domain Name to open a window displaying the Domain Schema and Source Data. This window provides a preview of the Domain file structure. By default, the Schema data displays. Click the Source Data tab to view the source data

    Exporter_9.png

  4. Click OK to close the window.

View Files in eDrive

For any import, a link for Files in eDrive displays at the bottom half of the window. Clicking this opens eDrive for that import, where you can then download the files. Select any import from the top half of the Imports window to access the files from the import you want.

Importer_08.png

Tip: If an import was unsuccessful, you can use this link to see if there are any associated log files. For example, for an SAS import that fails, you can find the log file mentioned in the error message by navigating in eDrive to the sas_etl subfolder.

View Import History

The History option within Importer provides the ability to see a record of all the imports for the selected study or Global Data Store. This includes all imports, whether they were successful or not.

  1. From the study-level Importer window, click History.

    Importer_09.png

  2. From the list, click on an import row to view the domains at the bottom of the window.

Best Practices Checklist

  • Define the Data Source first. Configure the URL, credentials, remote folder, remote study, API keys, and other necessary properties before building the Import Definition; manual file imports are the only exception.
  • Choose the simplest data source. Use out-of-the-box API connectors or S3 / Box pulls over custom SFTP scripts, as they require less setup and deliver data more quickly.
  • Validate column size. Keep unicode (nVarchar) columns under 4,000 characters to prevent truncation during importing.
  • Watch Study Import Control limits. If record-change thresholds are enabled and the import exceeds configured thresholds, the import will complete with a warning that elluminate will not import the data.
  • Schedule imports to avoid contention. A study can run only one import into a data store at a time. For example, Study A and Study B may import into their respective Clinical data stores simultaneously, but Study A cannot schedule two imports to run concurrently in its Clinical data store. Subsequent imports queue automatically, so stagger schedules for faster throughput.
