Package liquibase.change.core Description

Technically, a Change expresses an intention for alter the structure of the Database. An example would be: "Drop all foreign keys from a table". However, it abstracts from the way this is actually archieved: While one DBMS might provide a syntax for that (maybe something like "ALTER TABLE myTable DROP ALL FOREIGN KEYS"), others do not have a 1:1 translation and need to perform the change in several steps (e.g. enumerating all foreign keys and then dropping them one-by-one).

This package contains all the possible basic Changes that should be possible with every DBMS supported by Liquibase. Most classes here extend the AbstractChange class that provides the general frame for the Change.
