Two-Way Links with a source document sharing its data with the destination document and the destination document sharing that data (object) back to another location within the source document. An example of this might be where data originates in the word processor. This data might be marketing forecast data, for example. This data is linked to a spreadsheet where a chart is created based on the linked data. The chart is then linked back into the source document right below the forecast data. Once this Two-Way Link is established, a what-if analysis can be performed on the original source data such that if the data changes in the source, it is updated in the spreadsheet. The chart is then updated and finally, the chart is updated in the source document. So the ability to share data in a destination document and receive linked data back into the source document is a Two-Way Link.
In addition to simple links, it is possible to get arbitrarily complex by nesting links and combining linked and embedded objects.
