org.syncany.database.dao.DatabaseVersionSqlDao
The database version data access object (DAO) writes and queries the SQL database for information on {@link DatabaseVersion}s. It translates the relational data in the "databaseversion" table to Java objects; but also uses the other DAOs to persist entire {@link DatabaseVersion} objects. @see ChunkSqlDao @see FileContentSqlDao @see FileVersionSqlDao @see FileHistorySqlDao @see MultiChunkSqlDao @author Philipp C.
