AI Technical Summary

Benefits of technology

This approach enables rapid search and management of large datasets, reducing access time significantly and making it feasible to process data volumes that exceed 128 gigabytes without the need for expensive DRAM, thus enhancing data processing efficiency and cost-effectiveness.

Problems solved by technology

However, as DRAM capacity increases, the price of a DRAM serving as a semiconductor material rapidly increases as compared to a hard disk, resulting in a reduction of the cost efficiency of large amount of data that requires more than 128 Gigabytes.
In this case, a speed difference in data access time between the sequential access method and the random access method based on the highly integrated index technology may be several days to several years, such that the conventional art will be incapable of implementing data access or data search.

Embodiment Construction

[0060]Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. In the drawings, the same or similar elements are denoted by the same reference numerals even though they are depicted in different drawings. In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. Exemplary embodiments of the present invention provide a method for recording data in a disc and a method for searching for data in a disc.

[0061]FIG. 2 exemplarily shows the relationship among a data file, a Record Allocation Table (RAT) file, and a Rack of Virtual RAM (RVR) file according to the embodiments of the present invention. FIG. 3 exemplarily shows the relationship among an RVR file, a RAT file, and data stored in a disc according to the embodiments of the present invention....

Abstract

A method for creating / storing a file that facilitates search of data stored in a storage medium, and a data search method using the same are disclosed. The file creating method creates a rack of virtual RAM (RAM) file that is divided into several units according to divisional units for individual divisional units, and a record allocation table (RAT) file that stores a record position of each divisional unit of the RVR file. As a result, a database (DB) of large-volume irregular data can be easily created, and data analysis can be quickly achieved.

Description

CROSS REFERENCE TO PRIOR APPLICATIONS[0001]The present application is a Divisional Application of co-pending U.S. patent application Ser. No. 13 / 003,649 (filed on Mar. 21, 2011) under 35 U.S.C. §120, which is a National Stage Patent Application of International Patent Application No. PCT / KR2009 / 003790 (filed on Jul. 10, 2009) under 35 U.S.C. §371, which claims priority to Korean Patent Application No. 10-2008-0067778 (filed on Jul. 11, 2008), which are all hereby incorporated by reference in their entirety.BACKGROUND[0002]The present invention relates to a method for creating and storing a file that enables easier searching and a method for searching for data using the same.[0003]FIG. 1 is a conceptual diagram illustrating data stored in a general hard disk. The hard disk constructs a cylinder composed of a plurality of tracts constructing an original plate, and performs input / output (I / O) operations through a Read / Write header connected to a boom of each tract. In FIG. 1, it is ass...
