An easy method to import the data into the system. Typically this will only be done once, as then you will manage the data with in the PIM. But the system enables additional uploads to add data or update existing data.
The system has tools to easily view and update the data. Views allow you to filter, sort, and order the data in any manner. And you can have as many views as needed. Rules engine allows you to create simple rules to update and manipulate the data.
