Overlap Discovery Results

The

Overlap Discovery

tab displays information on the participating columns and the overlapping percentage value. The overlap discovery results include Venn diagrams that represent the overlapping data in pairs of columns and the date and time when you last performed overlap discovery.

You can click a column and select

Verify

to view the results as a Venn diagram.

The following table describes the overlap discovery properties:

Property	Description
Left Column	The primary column against which the remaining columns are compared for overlap analysis.
Right Column	The column that is compared to the primary column.
% Overlap	The percentage of overlap between two columns.
Verified	Indicates that you validated the overlap results row.
Last Run Time	The date and time that the overlap discovery last ran.

Informatica Developer displays each overlapping pair two times in the overlap discovery results. Consider data sources Items and Orders. Items has columns "m" and "n." Orders has columns "p" and "q."

The following table shows the overlap discovery results for Items and Orders:

Left Column	Right Column
Items	-
m	Orders.p
m	Orders.q
n	Orders.p
n	Orders.q
Orders	-
p	Items.m
p	Items.n
q	Items.m
q	Items.m
