Fast Hierarchical Enrichment

A programmed computer comprising at least a processor, a memory, a display device and an input device, wherein said computer is programmed to perform a method of generating computer instructions for creating instances of a hierarchical data format from a flat record stream, said flat record stream containing at least some data redundancy, the method comprising:

• allowing a developer to use said input device to create a graphical representation of said hierarchical data format;
• allowing a developer to use said input device to create a graphical representation of a mapping between said flat format and said hierarchical format;
• and
• generating, at said processor, computer instructions which when executed on a computer cause the computer to create from said flat record stream instances of said hierarchical format, and wherein said instances of said hierarchical format remove said data redundancy.

A computer-readable medium containing computer-readable instructions for performing a method of generating computer instructions for creating instances of a hierarchical data format from a flat record stream, said flat record stream containing at least some data redundancy, the method using a computing device having at least a processor, a memory, a display device and an input device, and the method comprising:

• allowing a developer to use said input device to create a graphical representation of said hierarchical data format;
• allowing a developer to use said input device to create a graphical representation of a mapping between said flat format and said hierarchical format;
• and
• generating, at said processor, computer instructions which when executed on a computer cause the computer to create from said flat record stream instances of said hierarchical format, and wherein said instances of said hierarchical format remove said data redundancy.
