This disclosure relates to improved techniques for generating SQL statements, including both DDL and DML statements. In certain embodiments, a relational metadata management system (RMMS) stores and maintains a metadata repository corresponding to one or more source databases. The RMMS can represent a SQL engine layer that is situated on top of a SQL engine and/or SQL database to facilitate higher levels of abstraction and reusability of the data included in the databases. The RMMS can include a SQL generator that utilizes the metadata stored in the metadata repository to generate the SQL statements for querying the one or more source databases.

Systems and methods for generation and management of SQL data definition and data manipulation statements via serially reusable metadata

A system and method which provides simultaneous display of characters on one or more display monitors in multiple languages. The languages can include icon based languages such as Chinese and Japanese or can be traditional character based languages such as romance and Germanic languages. The system includes a main unit having a first memory in which the first memory includes character data stored in a plurality of languages. A portion of the character data in a first language corresponds to another portion of the character data in a second language, the portion of the character data in the first language and the portion of the character data in the second language are stored in the first memory at memory locations having an offset value from each other.

Multiple simultaneous language display system and method

A method and apparatus is disclosed to improve the metal yield by adjusting the tilt angle of a tilting vessel having a submerged tap hole. The tilt angle is adjusted in response to parameters inherent in the pouring process, i.e. the proximity of the vessel contents to the vessel lip, the age of the tap hole, the liquid head over the tap hole, etc. Additionally, methods are disclosed to enhance the metal yield by advancing or moving back the furnace without knowledge of the tilt angle. Moreover, such methods and apparatus can be implemented through the use of computer based algorithms. The methods can also be used to archive pouring parameter information for future uses such as training and reviewing.

Method and apparatus for metal pouring

A method and apparatus for improving the yield of molten metal discharged from a metal production vessel limits the slag carryover by reducing turbulence of metal pouring through a discharge opening by inhibiting a vortex over the discharge opening, automatically sensing the presence of slag in the discharge opening, and terminating discharge through the opening in response to the detection of changing content through the discharged opening passage. Preferably, the inhibiting function includes inserting a slag reduction device, preferably a refractory body and maintaining the position of the device over the discharge nozzle. Preferably, the sensor is an electromagnetic coil that determines the change in content of the flow through the opening passage without direct contact with the contents of the opening. The combination of the slag vortex inhibitor and the flow content sensor is substantially improved metal pouring yield as demonstrated by actual slag reduction results.
