8. log on to the work repository (log on to the work repository through designer)For the first login, select "new". The logon name is arbitrary. The user name and password must be supervisor/sunopsis. F
Incrementword method is to record each word and its location. One thing to note is to add clearattributes () in front of you, otherwise you may see first position increment must be > 0 ... error.

are mainly divided into several categories (rkm, CKM, lkm, ikm, and SKM), among which the most important are lkm (load km) and ikm (integration km) rkm:
Rkm completes reverse engineering of the data structure of the source and target systems to form a data model.
CKM: CKM completes data quality check.
Jkm: the logging knowledge module that records new data and u

In spring, an AOP proxy can be either a JDK dynamic agent or a cglib proxy.Weaving (Weaving): Assembling aspects to create a notified object.
