Import sorce database and Target table . create mapping and drag and drop sorce and target table into mapping designer window. Establish a connection o! sorce sorce and target technolog& with with that o! particlar database. 2reate a model and *everse Engineering the datastore according to the technolog&. technolog&. 2reate new inter!ace inside pro?ect and then come to mapping tab and ma>e a mapping between sorce and target datastores. Then create E$pression E$pression Trans!ormation Trans!ormation to grop grop b& colmn. Then come to @ow tab and and denowledge modle modle based on sorce sorce and target.
