Abstract

The present invention relates to a system data abbreviation system and method. The system data abbreviation system includes a data mapping unit configured to classify system data, provided by an external database, into classes of a database of an internal application program and to then map the classified system data; a data search unit configured to search for data of the class to be abbreviated from the database of the application program; and a data abbreviation unit configured to group the found data of the class, to set link relations between data that belongs to the group, to set link relations between the group and the classes of the database of the application program, and to then abbreviate the data.

Claims

1. A system data abbreviation system, comprising:

a data mapping unit configured to classify system data, provided by an external database, into classes of a database of an internal application program and to then map the classified system data;

a data search unit configured to search for data of the class to be abbreviated from the database of the application program; and

a data abbreviation unit configured to group the searched data of the class, to set link relations between data that belongs to the group, to set link relations between the group and the classes of the database of the application program, and to then abbreviate the data.

2. The system data abbreviation system of claim 1, wherein the data mapping unit comprises:

a data classification unit configured to classify the system data of the external database into the data classes of the application program database;

a node generation unit configured to generate nodes based on the classes of the data; and

a mapping unit configured to perform mapping that generates a link structure between the nodes and the data.

3. The system data abbreviation system of claim 2, wherein the data classes of the database of the application program are each classified as a branch or a switch.

4. The system data abbreviation system of claim 2, wherein the mapping unit, if the link structure between the nodes and the data has not been generated, searches for a class similar to the class that the data belongs, and then performs the mapping.

5. The system data abbreviation system of claim 1, wherein the data search unit comprises:

a branch search unit configured to check whether lines have been connected to the node of the data in order to determine whether the corresponding data is a simple branch;

a switch search unit configured to check whether a switch provided at the node of the data is a manual switch or a user-designated switch; and

an abbreviation class extraction unit configured to, if the connected lines of the node are three or more in number or the switch provided at the node of the data is not a manual switch or a user-designated switch the node, extract the data of the corresponding class as an abbreviation class.

6. The system data abbreviation system of claim 1, wherein the data abbreviation unit comprises:

a grouping unit configured to group the class of the data to be abbreviated; and

a link relation setting unit configured to set link relations between the data that belongs to the group, and to set link relations between the group and the classes of the database of the application program.

7. The system data abbreviation system of claim 1, further comprising a system abbreviation database configured to store the link relations set by the data abbreviation unit.

8. A system data abbreviation method, comprising:

classifying system data, provided by an external database, into classes of a database of an internal application program, and then mapping the classified system data;

searching for data of the class to be abbreviated from the database of the application program; and

grouping the searched data of the class, setting link relations between data that belongs to the group, setting link relations between the group and the classes of the database of the application program, and then abbreviating the data.

9. The system data abbreviation method of claim 8, wherein classifying the system data into the classes of the database of the internal application program and then mapping the classified system data comprises:

classifying the system data of the external database into the data classes of the application program database;

generating nodes based on the classes of the data; and

performing mapping that generates a link structure between the nodes and the data.

10. The system data abbreviation method of claim 9, wherein performing the mapping, if the link structure between the nodes and the data has not been generated, comprises searching for a class similar to the class that the data belongs, and then performing the mapping.

11. The system data abbreviation method of claim 8, wherein searching for the data of the class to be abbreviated comprises:

checking whether lines have been connected to the node of the data in order to determine whether the corresponding data is a simple branch;

checking whether a switch provided at the node of the data is a manual switch or a user-designated switch; and

if the connected lines of the node are three or more in number or the switch provided at the node of the data is not a manual switch or a user-designated switch the node, extracting the data of the corresponding class as an abbreviation class.

12. The system data abbreviation method of claim 8, wherein abbreviating the data comprises:

grouping the data of the class to be abbreviated; and

setting link relations between the data that belongs to the group, and also setting link relations between the group and the classes of the database of the application program.
