File creating method for searching of data, searching method of data file and managing system for searching of data file

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.

What is claimed is: 
     
         1 . A file creation method for searching for a single irregular data file, the method comprising:
 (A1) receiving a divisional unit of data as an input;   (A2) discriminating the single irregular data file using the received divisional unit, and creating a rack of virtual RAM (RVR) file;   (A3) detecting a record position for each divisional unit of the RVR file, and creating a record allocation table (RAT) file; and   (A4) storing the RVR file and the RAT file.   
     
     
         2 . The method according to  claim 1 , wherein:
 the data is regular data, and   the divisional unit is any one of [page], [paragraph], [line] and [word].   
     
     
         3 . The method according to  claim 1 , wherein the record position is the size of data accumulated in the single data extended up to a specific position where corresponding data is recorded. 
     
     
         4 . The method according to  claim 1 , wherein the record position is a number of a hard disk cluster in which data of a corresponding part is recorded. 
     
     
         5 . A file creation method for searching for a single regular data file, the method comprising:
 (B1) discriminating between a row and a column of one regular data, and creating a rack of virtual RAM (RVR) file;   (B2) detecting a record position for each row or column of the RVR file, and creating a record allocation table (RAT) file; and   (B3) storing the RVR file and the RAT file.   
     
     
         6 . The method according to  claim 5 , wherein the record position is the size of data accumulated in the single data extended up to a specific position where corresponding data is recorded. 
     
     
         7 . The method according to  claim 5 , wherein the record position is a number of a hard disk cluster in which data of a corresponding part is recorded. 
     
     
         8 . The method according to  claim 5 , wherein the record position is the size of data accumulated in the single data extended up to a specific position where corresponding data is recorded. 
     
     
         9 . The method according to  claim 5 , wherein the record position is a number of a hard disk cluster in which data of a corresponding part is recorded. 
     
     
         10 . A method for searching for a single data file, the method comprising:
 (C1) receiving search information;   (C2) detecting a record position contained in single data corresponding to searched information from a record allocation table (RAT) file;   (C3) detecting a physical storage position contained in a storage medium of data corresponding to the searched information from the record position; and   (C4) searching for data of a physical position of the data, and outputting the searched result.   
     
     
         11 . The method according to  claim 10 , wherein, if the single data is irregular data, the searched information is an order of each divisional unit. 
     
     
         12 . The method according to  claim 10 , wherein, if the single data is regular data, the searched information is a number of a row or column of corresponding data from among the regular data. 
     
     
         13 . The method according to any one of  claim 10 , wherein the record position is the size of data accumulated in the single data extended up to a specific position where corresponding data is recorded. 
     
     
         14 . The method according to  claim 13 , wherein the detecting step (C3) of the storage position includes:
 calculating a cluster position from the record position using a size of data of each divisional unit, reading a physical storage position of the cluster position from a file allocation table (FAT), and detecting the read physical storage position of the cluster position.   
     
     
         15 . The method according to any one of  claim 10 , wherein the record position is a number of a hard disk cluster in which data of a corresponding part is recorded. 
     
     
         16 . A method for searching for a data file, the method comprising:
 (D1) fragmenting a genome base sequence into predetermined-sized base units;   (D2) allocating a unique number to each fragmented base unit;   (D3) storing a storage position of each base unit; and   (D4) creating a record allocation table (RAT) file.   
     
     
         17 . The method according to  claim 16 , wherein the unique number in the step (D2) is a tetramal number classified according to bases constructing the base unit. 
     
     
         18 . A method for searching for a data file, the method comprising:
 (E1) assigning a serial number to input data according to a divisional unit;   (E2) calculating a serial number of data that includes a word contained in the input data;   (E3) creating a hash table including the word and the serial number; and   (E4) creating a record allocation table (RAT) using the hash table.
