Abstract

Systems and methods store information data in an information data frame, including retrieval keys, and store pertinent data specifying the information data in a pertinent data frame for each individual category specified by the retrieval keys. The systems and methods receive an updating file containing updating information data for updating information data subject to update. The systems and methods extract the information data subject to update from the information data frame and update the extracted information data with the updating information data contained in the received updating file. The systems and methods extract the pertinent data in a category specified by a retrieval key contained in the information data subject to update from the pertinent data frame and update the extracted pertinent data with the updating information data contained in the updating file.

Claims17

Dependent claims

A data management system, comprising:

a storage medium that:
for an individual spot, stores information data in a corresponding information data frame, the information data including specific information about the particular spot that is subject to update;
for the same individual spot, stores pertinent data in a pertinent data frame that is stored separate from the information data frame, the pertinent data including:
a name of the spot;
offset data that specifies the information data for the spot that is stored in the information data frame;
and
retrieval key information usable to identify the pertinent data based on a search for the spot using input retrieval keys;
and
stores category data in a category frame, the category data usable to identify the pertinent data for the spot based on the retrieval key information in the pertinent data;
and
a CPU that:
receives an updating file containing updating information for the spot, the updating information corresponding to only the information data in the information data frame, the received updating file not containing updating pertinent data;
for the individual spot:
first compares the information data to the updating information;
based on the first comparison, determines which portion of the information data is subject to update;
extracts the information data subject to update from the information data frame;
updates the extracted information data with the updating information data for the spot contained in the received updating file;
identifies the pertinent data for the spot stored in the pertinent data frame by using a retrieval key contained in the information data subject to update from the pertinent data frame;
second compares the identified pertinent data for the spot to the updating information;
based on the second comparison, determines which portion of the pertinent data is subject to update;
extracts the pertinent data subject to update from the pertinent data frame;
and
updates the extracted pertinent data with corresponding parts of the updating information corresponding to only the information data contained in the updating file.

storing, for an individual spot, stores information data in a corresponding information data frame, the information data including specific information about the particular spot that is subject to update;
storing, for the same individual spot, stores pertinent data in a pertinent data frame that is stored separate from the information data frame, the pertinent data including:
a name of the spot;
offset data that specifies the information data for the spot that is stored in the information data frame;
and
retrieval key information usable to identify the pertinent data based on a search for the spot using input retrieval keys;
storing category data in a category frame, the category data usable to identify the pertinent data for the spot based on the retrieval key information in the pertinent data;
and
receiving an updating file containing updating information for the spot, the updating information corresponding to only the information data in the information data frame, the received updating file not containing updating pertinent data;
for the individual spot:
first comparing the information data to the updating information;
based on the first comparison, determining which portion of the information data is subject to update;
extracting the information data subject to update from the information data frame;
updating the extracted information data with the updating information data for the spot contained in the received updating file;
identifying the pertinent data for the spot stored in the pertinent data frame by using a retrieval key contained in the information data subject to update from the pertinent data frame;
second comparing the identified pertinent data for the spot to the updating information;
based on the second comparison, determining which portion of the pertinent data is subject to update;
extracting the pertinent data subject to update from the pertinent data frame;
and
updating the extracted pertinent data with corresponding parts of the updating information corresponding to only the information data contained in the updating file.
