How portal fetch the data from wmtables

Hi,

WM uses JDBC Pool aliases to connect to back end databases. You can see the same through Settings->JDBC Pools->Pool Alias Definitions.

The WM tables are internal canonical which you cannot understand directly and if i were you i wouldn’t mess with those tables.
