Abstract: A method for obtaining access to database files in a computing system includes receiving, at an operating system, a first call from a database management system requesting access to a database file; creating, by the operating system, a data expanse file; and allowing the database management system to request views of data in the data expanse file by using an instruction processor and a view instruction. A computer program product may include a non-transitory computer-readable medium comprising instructions which, when executed by a processor of a computing system, cause the processor to perform the following actions: receiving, at an operating system, a first call from a database management system requesting access to a database file; creating, by the operating system, a data expanse file; and allowing the database management system to request views of data in the data expanse file by using an instruction processor and a view instruction.

Abstract: A method for processing an operand by an operating system includes receiving, at the operating system, a set of interrupts from a view operand; wherein a first interrupt causes the operating system to create a postern, a second interrupt causes the operating system to delete a specified postern and the remaining interrupts are transformed into a user status that is placed in the operand. A non-transitory machine readable memory medium including instructions when executed to cause a processor to perform the following actions: receiving, at the operating system, a set of interrupts from a view operand; wherein a first interrupt causes the operating system to create a postern, a second interrupt causes the operating system to delete a specified postern and the remaining interrupts are transformed into a user status that is placed in the operand.

Abstract: A method includes receiving, from a database management system, a view instruction, using a single band descriptor able to describe 2**60 words of space, defined as a data expanse; creating, by an operating system, the data expanse in response to the view instruction; and allowing an activity to access a subset of the data expanse with a postern; wherein fast access to data whose size exceeds the available virtual address space is available.

Abstract: A method for obtaining access to database files in a computing system includes receiving, at an operating system, a first call from a database management system requesting access to a database tile; and creating, by the operating system a memory-mapped data expanse file by automatically populating the data expanse file via a bit map and an interrupt from a view instruction from the database management system, A computer program product may include a non-transitory computer-readable medium comprising it which, when executed by a processor of a computing system, cause the processor to perform the following actions: receiving, at an operating system, a first call from a database management system requesting access to a database file; and creating, by the operating system a memory-mapped data expanse file by automatically populating the data expanse file via a bit map and an interrupt from a view instruction from the database management system,

Abstract: A computing system includes a database, an operating system and a database management system. The computing system also includes an instruction processor in communication with the database management system; the database management system having a bank, a RDMS data expanse and a view mechanism; the operating system having a data expanse view control in communication with the hank and a data expanse view control in communication with the RDMS data expanse; wherein the database management system can request a data expanse file be created at the operating system and can request a view of the data expanse file using a view instruction from the instruction processor.
