Matching columns in tables

If your data contains a common, general type of information that the application recognizes, the application suggests related information that you can use to enhance your data and research. As data is processed, the application analyze the data type and format of each field in an attempt to match it to any known data types in the system. When a potential match is discovered, it is indicated on the user interface and users can take action to add matched columns and related columns.

To add matched columns to a table:

  1. In the Project workspace, browse to a table in your project.

  2. Look at the column headers in the table to locate a Green Triangle green_arrow.png indicator.

  3. Click the arrow in the field and click the Match this column option.

  4. In the window that opens, you see a list of possible matching columns with an option to browse to the source of the column. Click the Add matched column button to add the column to the table. Once you do that, you are presented with a list of possible Related columns for the matched column. Click the Add related column button to add any related columns.


    Note that if a new version of the original file is uploaded (with additional rows of data, or additional columns), the file will automatically be matched using the same algorithm.

  5. The matched and related columns are shown in the main table. Click the values of fields in these matched and related columns to view additional information about the fields.

  6. To remove matched and related columns from the table, click the arrow in the field and click the Remove from table option.
