Patent number: 5749079Abstract: An end user query technology is taught which is capable of automatically understanding the database model and guiding the user to scout for the desired information, thereby increasing productivity and ease of information access. The user is freed from the need to understanding the database model, with the end user query facility of this invention quickly guiding the user to acquire the information. This is made possible by the end user query facility of this invention first recapturing the application semantics from the existing database model to provide a set of derived semantics. The derived semantics are then used by the end user query facility to intelligently guide the user to scout for the desired information in the database. In addition, the derived semantics can be easily updated by the end user query facility when the database model is changed.Type: GrantFiled: January 26, 1995Date of Patent: May 5, 1998Assignee: Singapore Computer Systems LimitedInventors: Dennis Yong, Viktor Choong-Hung Cheng, Christopher Leng-Hong Yo, Liat Lim

Patent number: 5432887Abstract: Methods are developed on a digital computer for performing work order scheduling activity in a dynamic factory floor environment, in a manner which enables scheduling heuristic knowledge from a scheduler to be encoded through an adaptive learning process, thus eliminating the need to define these rules explicitly. A sequential assignment paradigm incrementally builds up a final schedule from a partial schedule, assigning each work order to appropriate resources in turns, taking advantage of the parallel processing capability of neural networks by selecting the most appropriate resource combination (i.e. schedule generation) for each work order under simultaneous interaction of multiple scheduling constraints.Type: GrantFiled: March 16, 1993Date of Patent: July 11, 1995Assignee: Singapore Computer SystemsInventor: Fook C.

Patent number: 5307499Abstract: An object-oriented technology is provided which is capable of operating interpretively to allow prompt and easy prototyping and debugging using a compiled class library, and which is also capable of operating after compilation, thereby providing excellent performance. A software facility allows direct access to class attributes and direct invocation of class methods defined in pre-compiled classes in a class library in an interpretive mode. When this facility is used with or embedded within an application development environment, it allows an application builder to interactively build prototypes as well as production quality applications rapidly. When the facility is integrated with an object-oriented database, it allows interactive query and data manipulation using pre-complied classes.Type: GrantFiled: May 20, 1993Date of Patent: April 26, 1994Assignee: Singapore Computer Systems LimitedInventor: Fong K.
