Creating, Modifying, and Deleting Tables

  

An interval data table stores interval data in a spreadsheet, where each interval is stored as a separated row.  Since every interval row in the table shares the same fields (as columns), it's a good idea to keep different types of data in different tables.

To create, modify, or delete tables in a Petra project:

Click the Maintenance button on the Main Module Interval tab.

Adds a new interval data table.  Selecting this option brings up a dialogue box to add the new tables name and description.  A newly created table contains no new fields

Edits just the name and description of an existing interval data table.  To edit the fields inside the interval, select the Data Fields option on the Maintenance screen

Deletes the entire interval data table, along with all the fields and data contained within the table
