org.apache.derby.iapi.sql.dictionary.DataDictionary
The DataDictionary interface is used with the data dictionary to get descriptors for binding and compilation. Some descriptors (such as table and column descriptors) are added to and deleted from the data dictionary by other modules (like the object store). Other descriptors are added and deleted by the language module itself (e.g. the language module adds and deletes views, because views are too high-level for modules like the object store to know about). @version 0.1
