2 is a configuration diagram showing a configuration of a data control system according to an embodiment of the present invention.

Referring to FIG. 2, the data control system 200 may include a file table 210, an information generating unit 220, a dedicated table 230, and a tree rejection 240.

In one embodiment, the data control system 200 may be an electronic device such as a portable terminal, a notebook computer, a computer, or the like, or may be included in a storage device and executed.

The file table 210 stores file data. File data refers to all data stored in a file format, and may include, for example, photographs, moving pictures, music, documents, and the like. One piece of file data includes information such as a full path, folder information, media type, time, name, text, image, size, and the like. All the file data newly created or modified in the device in which the data control system 200 is executed is stored in the file table 210. [

Accordingly, as the file table 210 becomes larger, the time required to provide the requested file data increases. This is because, in order to provide the requested file data, all the file data stored in the file table 210 is checked, and the requested file data is grouped and provided.

3 is a diagram showing an example of requesting data of the related art and the present invention.

Referring to FIG. 3, according to the related art 310, in order to group file data having the same bucket_id (folder's id), all the file data stored in the file table are scanned as a whole, Are grouped according to the stored folders, and sorted by name or time. The prior art 310 may be an example of requesting data in a device using an Android operating system.

For example, although the requested file data is a photograph or a moving picture, various file data such as music, folder, thumbnail foler, and document are included in a scan object in addition to a photograph and a moving picture, . That is, as the number of file data increases, it takes a long time to scan the entire file data stored in the file table 210, so that the rate of the file data until the file data is provided may be slowed in proportion to the number of file data.

Therefore, the present invention aims to shorten the time required to provide information by reconstructing information based on a specific column of a file table. In the present invention (320), information related to query execution to be a scan target is reconstructed using file data and stored in a dedicated table (TAVLE gallery_album). When data is requested, information stored in a dedicated table is scanned and provided have. For example, the dedicated tables may be composed of a plurality of media types.

In this case, in the conventional technology 310, the object to be scanned is the entire file data stored in the file table, whereas in the present invention 320, the object to be scanned is different because it is the information stored in the dedicated table. That is, since the scan object is limited to being associated with the requested data, the time required to scan the data is significantly reduced compared to the conventional method.

To this end, the information generation unit 220 of the data entry data system 200 may reconstruct information related to the query execution using the file data stored in the file table 210. The information can be reconstructed by extracting some information from the file data. In an embodiment, the information generation unit 220 may reconstitute, as information, at least one of a folder identifier, a media type, a folder name, and a data name associated with the file data.

The information may be stored in a dedicated table 230. For example, the information may be a sequence of various information fields included in the file data. Alternatively, the user can confirm that the thumbnail of the music cover image is an image and execute the album application, or display the above information first when using other related images. That is, the information relates to an object to be scanned or information to be provided when a user requests file data.

4 is a diagram showing an example of a file table and a dedicated table according to an embodiment of the present invention.

4, the file data 410 stored in the file table may include a full path, a folder ID Bucket_Id, folder information including a folder name (Buket_display), a media type (Media_type), a time, a data name (_data) Text, image, size, and the like.

On the other hand, the information 420 stored in the dedicated table may include at least one of a folder identifier (Bucket_Id), a media type (Media_type), a folder name (Buket_display) and a data name (_data).

In another embodiment, the information generating unit 220 may reconstruct information corresponding to the file data excluding the file data including the tag information. The tag information is information that is automatically generated when the file data is generated, and can easily identify the file data. Therefore, the information generating unit 220 can reconstruct information on the file data without the tag information. That is, the information can be used as tag information.

In an embodiment, the information generating unit 220 may include tag information according to a user's setting or tag information according to a file data attribute in the reconstructed information. That is, the tag information according to the setting of the user or the tag information according to the file data attribute may be the same as or different from the tag information that is automatically generated when the file data is generated. This is because the tag information is generated according to the setting of the user or the file data attribute.

The dedicated table 230 may be generated for each media type, and may include a plurality of dedicated tables 231 to 233. For example, the dedicated table 1 231 stores information on the media type 1, the dedicated table 2 232 stores information on the media type 3, and the dedicated table 3 233 stores information on the media type 5 Can be stored.

After creating the dedicated table 230, the tree rejection 240 of the data control system 200 can synchronize the file table 210 and the dedicated table 230 with each other. That is, when the file data stored in the file table 210 is changed, the tree rejection 240 can change the information of the dedicated table 230 corresponding to the file data.

In an embodiment, the tree rejection unit 240 may be a tree rejection unit 240, if it corresponds to at least one of a predetermined period, a real time, a data control system 200, a user's execution request, The table 210 and the dedicated table 230 can be synchronized with each other. Alternatively, the tree rejection 240 may not synchronize the file table 210 and the dedicated table 230 according to the user's setting.

5A and 5B illustrate an example of synchronizing a file table and a dedicated table when file data is inserted according to an embodiment of the present invention.

Referring to FIGS. 5A and 5B, when new file data is inserted into the file table, the tree rejection unit 240 can insert information corresponding to the file data into the dedicated table. At this time, the tree rejection unit 240 can check the media type and determine whether or not tag information is included in the file data. The tree rejection 240 may not synchronize the file table and the dedicated table when file data with tag information is inserted. However, the tree rejection 240 inserts the information associated with the file data in the dedicated table 520 when the file data without tag information (/Samsung/2013-08-31/Photo_0001.jpg) is inserted, The table 510 and the dedicated table 520 can be synchronized.

6A and 6B illustrate an example of synchronizing a file table and a dedicated table when file data is updated according to an embodiment of the present invention.

Referring to FIGS. 6A and 6B, when the file data stored in the file table is updated, the tree rejection unit 240 can change the information corresponding to the file data in the dedicated table. At this time, the tree rejection unit 240 can check the media type and determine whether or not tag information is included in the file data. Tree rejection 240 changes the information associated with the file data in the dedicated table 520 when the file data without tag information (/Samsung/Videos/Videos1-1.avi) changes, The table 620 can be synchronized.

7A and 7B illustrate an example of synchronizing a file table and a dedicated table when file data is deleted according to an embodiment of the present invention.

Referring to FIGS. 7A and 7B, when the file data stored in the file table is deleted, the tree rejection unit 240 can delete information corresponding to the file data from the dedicated table. At this time, the tree rejection unit 240 can check the media type and determine whether or not tag information is included in the file data. Tree rejection 240 deletes the information associated with the file data from the dedicated table 720 when the file data without tag information (/Samsung/Camera/Image1.png) is deleted, Gt; 720 < / RTI >

8 is a flowchart illustrating a data control method according to an embodiment of the present invention. The data control method may be performed by a data control system.

Referring to Fig. 8, in step 10, the file table of the data control system stores file data. File data refers to all data stored in a file format, and may include, for example, photographs, moving pictures, music, documents, and the like. One file data includes many kinds of information fields such as a full path, folder information, media type, time, name, text, image, size, and the like. All file data newly created or modified in the device in which the data control system is executed is stored in the file table.

In step 20, the information generating unit of the data control system reconstructs information related to the execution of the query using the file data. The information generating unit may identify the media type and reconstruct information corresponding to the file data excluding the file data including the tag information. The tag information is information that is automatically generated when the file data is generated, and can easily identify the file data. Therefore, the information generator can reconstruct information on the file data without the tag information.

The information can be reconstructed by extracting some information from the file data. In an embodiment, the information generating unit may extract at least one of a folder identifier, a media type, a folder name, and a data name associated with the file data as information. That is, the reconstructed information can be used as tag information. For example, the information may be a sequence of various information fields included in the file data. Alternatively, you can run the album application, or you can show this information first when you are using other images. That is, the information relates to an object to be scanned or information to be provided when a user requests file data.

In an embodiment, the information generator may include tag information according to a user's setting or tag information according to a file data attribute in the reconstructed information. That is, the tag information according to the setting of the user or the tag information according to the file data attribute may be the same as or different from the tag information that is automatically generated when the file data is generated. This is because the tag information is generated according to the setting of the user or the file data attribute.

In step 30, a dedicated table of the data control system stores the information. The dedicated tables may be generated for each media type, and may include a plurality of dedicated tables. For example, dedicated table 1 stores information on media type 1, dedicated table 2 stores information on media type 3, and dedicated table 3 stores information on media type 5.

In step 40, the tree denial of the data control system can determine whether the file table is changed. Wherein the tree rejection checking unit determines whether at least one of conditions of at least one of a predetermined period, a real time, a data control system, and a user's execution is satisfied, and if the condition is satisfied, Can be confirmed.

In step 50, the tree denial of the data control system may synchronize the file table and the dedicated table with each other.

In an embodiment, when the new file data is inserted into the file table, the tree rejection may insert information corresponding to the file data into the dedicated table. At this time, the tree rejection can check the media type and determine whether tag information is included in the file data. The tree rejection may not synchronize the file table and the dedicated table when file data with tag information is inserted. However, in the tree rejection, when file data without tag information is inserted, the file table and the dedicated table can be synchronized by inserting information associated with file data into the dedicated table.

Alternatively, when the file data stored in the file table is deleted, the tree rejection may delete information corresponding to the file data from the dedicated table. At this time, the tree rejection checks the media type to determine whether or not tag information is included in the file data, and deletes information associated with the file data from the dedicated table when file data without tag information is deleted, The file table and the dedicated table can be synchronized.

Alternatively, the tree rejection may not synchronize the file table and the dedicated table with each other according to the setting of the user or by default.

9 is a configuration diagram showing a configuration of a data control system according to another embodiment of the present invention.

9, the data control system 900 may include an information generating unit 920, a plurality of dedicated tables 930, and a tree rejecting unit 940.

The information generation unit 920 reconstructs information related to query execution using the file data stored in the media database 910. In an embodiment, the information generation unit 920 can confirm the media type and reconstruct information corresponding to the file data excluding the file data including the tag information among the identified media types. That is, the information can be used as tag information.

Alternatively, the information generation unit 920 may extract at least one of a folder identifier, a media type, a folder name, and a data name associated with the file data as information. For example, the information may be a sequence of various information fields included in the file data. Alternatively, you can run the album application, or you can show this information first when you are using other images. That is, the information relates to an object to be scanned or information to be provided when a user requests file data.

The information generation unit 920 may include the tag information according to the user's setting or the tag information according to the file data attribute in the reconstructed information. That is, the tag information according to the setting of the user or the tag information according to the file data attribute may be the same as or different from the tag information that is automatically generated when the file data is generated. This is because the tag information is generated according to the setting of the user or the file data attribute.

A plurality of dedicated tables 930 stores the information for each media type. That is, the dedicated table 1 931 to the dedicated table 3 933 for storing information according to each media type can be configured.

The tree rejection unit 940 changes information stored in the dedicated tables 930 according to the file data. The tree rejection unit 940 can change the information of the dedicated table 930 corresponding to the file data when the file data stored in the media database 910 is changed.

In an embodiment, the tree rejection 940 may be applied to the media in a predetermined period, in real time, at the time of operation of the data control system 900, at the time of execution of the user's request, The database 910 and the dedicated table 930 can be synchronized with each other. Alternatively, the tree rejection 940 may not synchronize the file table and the dedicated table with each other according to the user's settings or by default.

Hereinafter, the information generation unit 920, the plurality of dedicated tables 930, and the tree rejection unit 940 are similar to those of FIG. In Fig. 9, the media database may be the same as or different from the file table.

The information providing unit 950 provides the information stored in the dedicated tables 930 according to the media type requested to be executed. For example, the information providing unit 950 can check the media type and determine whether tag information is included in the file data. The information providing unit 950 may extract and provide the file data from the media database 910 when the media type requested to be executed corresponds to the file data having the tag information. However, if the media type requested to be executed corresponds to file data having no tag information, the information providing unit 950 can reconstruct information from the dedicated table 930 and provide it.

Accordingly, the data control system 900 can extract and provide the file data with ease by using the tag information, and the file data without the tag information extracts and provides the information from the dedicated table, The provision time can be shortened.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the claims.
