A non-transitory computer-readable storage medium storing a program that causes a computer to execute a processing, the processing including identifying, by a plurality of processes, at least one candidate for a record separation point from text data in each of a plurality of divided files, detecting, from the text data in the plurality of divided files, a text region indicating one data value based on a detection result of predetermined format code, determining that the at least one candidate that is not included in the text region is a record separation point, and transmitting a plurality of partial texts corresponding to the pieces of record data to one or more processes that transforms the plurality of partial text into a record format data, each of the plurality of partial texts being extracted from the plurality of divided files based on the determined record separation point.

Non-transitory computer-readable storage medium, record data processing method, and record data processing apparatus

A disclosed data structure of a phrase tree includes, as data of each node in the phrase tree, a data block including a first area for holding a code for a character or a character string, a second area for holding, for each character that will be used, an appearance sequential number of a second character that appears next to the character or the character string, and a third area for holding, according to the appearance sequential number, a number of appearances or a code corresponding to a character string comprising the character or the character string and the second character when the number of appearances exceeds a threshold.

Code processing technique

A data management apparatus includes a storage device; and a processor that executes a procedure, the procedure including selecting a data group, each data in the data group including one of a plurality of tags, among a plurality of data, compressing the data group into a compressed data group, and storing the compressed data group in the storage device, the stored compressed data group being associated with tagging information which indicates that each data of the data group includes the certain tag.

Data managing method, apparatus, and recording medium of program, and searching method, apparatus, and medium of program

A database management apparatus is provided with a setting unit that receives a snapshot request and records information indicating an extraction range to a memory, an extraction unit that sequentially extracts records and records the extracted records to another area, a monitoring unit that records information indicating an extraction-completed area and an extraction-remaining area, an update unit that judges whether a record targeted by an update instruction for update by a subsequent transaction is in the extraction-completed area, updates the update target record in the extraction-completed area if in the extraction-completed area, and records a map of the update target record in the extraction-remaining area to an area outside the extraction range and updates the map if in the extraction-remaining area, and a restore unit that updates the update target record to be the same as the map, after extraction of the update target record is completed.
