These Nodes allow you to manipulate the Presence Data Table by filtering out data, dropping rows, columns, adding columns, etc.

The following Nodes are currently available:

• Data Filter - restricts data to that which has changed since the last execution time.
• Require Columns - Tells the rest of the task that column names are available
• Append Data Column - Adds an extra column to the Data Dable, populated with the value(s) specified.
• Multiple Column Appender - Adds multiple columns to the Data Table
• Drop Column - Drops a column of data from the Data Table
• Drop Row(s) - Drops one ore more rows from the Data Table depending on Rules set.
• Calculate Column Aggregate - Calculates averages, minimums, maximums and counts on the data.
• Dataset Splitter - Splits the data into chunks based on differing values. Each chunk uses a separate Execution Path.
• Merge Results - Merges chunks of data from separate execution paths into one Data Table.
• Clear Data Table - Resets the Context Data Table to have zero rows and zero columns.
• Sort Data Table - Re-orders the Data according to the column order specified.
• Store Data Table - Temporarily stores the Data in a Presence Variable for later use.
• Retrieve Data Table - Retrieves the temporarily stored Data Table (see above).
