  • Although a great deal of research effort has been expended in support of natural language (NL) database querying, little effort has gone to NL database update. One reason for this state of affairs is that in NL querying, one can tie nouns and stative verbs in the query to database objects (relation names, attributes and domain values). In many cases this correspondence seems sufficient to interpret NL queries. NL update seems to require database counterparts for active verbs, such as "hire," "schedule" and "enroll," rather than for stative entities. ...

  • In Oracle Database, the OracleJVM has a new memory model for sessions that connect to the database through a dedicated server. Since a session using a dedicated server is guaranteed to use the same process for every database call, the Process Global Area is used for session specific memory and object allocations. This means that some of the objects and resources that used to be reclaimed at the end of each call can now live across calls.
