Having a Liquibase changelist (containing create table/column, alter table/column) I create a inmemory-database to create Hibernate entity-classes out of this inmemory-database. But the main task of Liquibase-Changelist is to update the structure of the database on a successfull deploy (guarranteed by the system-integraion-tests). This way the Database is the SSOT, naturally.
My assumptation is that the SVOT is technically the database, conceptionally the liquibase-changes and as a layer of the service, the entitys.
Can i say the liquibase changelogs are the Single source of the version of truth (SSOVOT)?
