That is, the controller 180 may execute the second application in the background area while executing the first application in the foreground area (that is, the activated state) (ie, deactivate the state).

The user input unit 130 may detect various gestures using a touch sensor. In one embodiment, the gesture is a tap, drag, flick, swipe, double tap, and touch & hold gesture using a finger or stylus, etc. It may include.

A tap gesture is the most basic gesture of touching a user interface element of a screen, and means a motion of touching a touch screen or a finger or a stylus for a short time. It means the same motion as the single click of the mouse. Touch motion, long press motion, etc. may mean the same motion.

The drag gesture refers to a motion of scrolling in a specific direction while touching the screen. For example, drag gestures are used to scroll up and down the screen in scrollable user interface elements.

Flick gestures are gestures that take a drag gesture but release a finger or stylus from the touch screen in a short time. For example, flick gestures are used to quickly scroll up and down the screen in scrollable user interface elements.

Swipe gesture refers to a gesture that takes a drag gesture but strongly drags a finger or a star illustration on the touch screen. For example, drag gestures are used to display a hidden delete menu corresponding to each item in a list.

Double tap gestures refer to two consecutive tap motions, for example, to zoom in or center content or an image, or to zoom out.

Touch and hold gesture refers to a motion of maintaining a predetermined time while touching a finger or a stylus on a touch screen. Touch and hold gestures are also called long presses. Used to display an enlarged view of the position of the cursor in editable text.

Meanwhile, the touch screen of the mobile terminal 100 may recognize a multi touch. In this case, the gesture may further include pinch open and pinch close gestures.

A pinch open gesture refers to a gesture of spreading two fingers together while touching the touch screen as if extending the screen. Pinch open gestures are used to zoom in on the map screen in the map view. The double tap gesture is used to automatically zoom in by a predetermined magnification, but the pinch open gesture is used to adjust the zoom in level based on the degree of the user's finger spreading.

The pinch close gesture is an opposite gesture of the pinch open gesture, and means a gesture of touching two fingers on the touch screen as if the screen is narrowed. For example, a pinch open gesture is used to zoom out of a map screen in map view.

Also in one embodiment, the gesture may be performed in an area where no user interface element (graphical object) is displayed. For example, the user may perform a horizontal or vertical swipe gesture passing through a blank area of the screen in the mobile terminal 100. In another embodiment, the user may touch or tap, for example, the top, bottom, left or right portion of the blank area on the screen. In another embodiment, a navigation guide (or indicator) may be displayed on the screen. The user can, for example, touch or swipe the area of the indicator.

The gesture for selecting an object may be a touch or tap gesture of the object. When the user input unit 130 detects a touch or tap gesture of the object, the controller 180 may execute an application corresponding to the object.

The gesture of selecting another object may be a long press (meaning a touch or tap for a predetermined time) gesture of the object. When the user input unit 130 detects the long press gesture of the object, the controller 180 may provide a user interface for managing the object or an application corresponding to the object. Examples of such a user interface may include moving or deleting an object.

Also, a plurality of objects may constitute an object group. The object group may be one object and may include a plurality of objects at the same time. For example, an object group may include an object, and another object group may be included. The type of gesture that may be applied to the object group may be the same as the gesture that may be applied to the object group. However, when an object is selected, a corresponding application may be executed, whereas when an object group is selected, an object included in the object group or another object group may be displayed.

Multiple objects may also constitute a page. A page refers to a view on the display. That is, a page is a unit capable of displaying one or more objects on a display, and the one or more objects may or may not be associated with each other. There may be a plurality of pages, and the plurality of pages may be randomly accessed by the page indicator. That is, each page may be able to arbitrarily switch from one page to another by a gesture of tapping the page indicator.

3 is a diagram illustrating a database hierarchy of a mobile terminal according to an embodiment of the present invention.

The database layer 200 of the mobile terminal according to an embodiment of the present invention may include an application layer 210, a framework layer 220, and a physical database layer 230.

The application layer 210 may include various applications such as an email client, an SMS, a map, a browser, and a contact that are developed using a software development kit (SDK).

The framework layer 220 may include a content resolver 222 and a content provider 224. The content resolver 222 may return a specific content provider 224 using the access rights of the available content providers 224 and a uniform resource identifier (URI). The content provider 224 may be accessed through the content resolver 222 as an interface for accessing data between different applications.

The database layer 230 is composed of a flash memory file system and a database management system such as SQLite, and may be a physical storage device in which actual data is stored.

In the mobile terminal 100, an object called a cursor may be returned as a return value for a query of the content resolver 222. A cursor is a pointer for accessing data extracted from a query and can be used for sequential access and random access. Cursors can also serve as a separate interface from internal database management systems and applications.

4A is a diagram illustrating a configuration of a translation lookaside buffer (TLB) according to an embodiment of the present invention.

The cursor translation layer 300 may include a cursor interface layer 310, a manager layer 320, a cursor translation index buffer 330, a RAM resident data structure 340, and physical cursors 350.

Cursor interface layer 310 may provide an interface between manager layer 320 and cursor translation index buffer 330, and an interface between the platform and cursor translation index buffer 330.

The manager hierarchy 320 includes a column windowing manager that manages the conversion of virtual columns into physical columns, a sync handler manager that provides data synchronization between multiple physical cursors, and user-defined columns. It may include a managing a virtual field manager (Virtual Field Manager).

Cursor translation index buffer 330 allows the conversion of multiple physical cursors into virtual cursors. Each item of the cursor translation index buffer 330 may consist of an index of the virtual cursor, a type (type) of the physical cursor, and an actual position within the physical cursor. For example, when the application accesses the second item of the cursor translation index buffer 330, the controller 180 may internally access the actual record after converting to the first index of the SMS cursor.

The RAM resident data structure 340 refers to a set of data structures for data processing for user defined columns. To this end, the mobile terminal 100 may be provided with a user-defined column addition function and a data processing function. The controller 180 may generate a column that cannot be mapped using a user-defined column addition function, and may acquire data of a specific record by registering a data processing function that is called when the column is accessed.

The data processing function may be implemented in various forms, and may directly transfer data residing in the volatile region of the memory 160 or return data through a separate data manipulation. In addition, data stored in a database of the memory 160 may be used as well as data on a network or a file.

The cursors 350 may be pointers for accessing data extracted as a result of the query of the content resolver 222.

4B is a diagram for describing column mapping information according to an embodiment of the present invention.

The virtual column table 410 may be mapped to the physical column table 420. The virtual column table 410 may include a fixed message column FIXED_MSG_COLUMNS and a real column name for each fixed message column. For example, the actual column name for MSG_COL_MESSAGE_ID may be "msg_id".

In addition, the physical column table 420 may include a fixed message type column FIXED_MMS_COLUMNS and a real column name for each fixed message type column. For example, the actual column name for MMS_COL_MESSAGE_ID may be "_id". Here, the column whose actual column name is "" is a column which does not exist in the actual database, so that data can be obtained using the RAM resident data structure 340. Also, a column whose null column name is null will return null or 0 without any manipulation. Accordingly, an error message may be output.

4C to 4F are diagrams for describing column mapping information according to an embodiment of the present invention.

In FIG. 4C, the physical column table 420 may be mapped to the full index table 430 and the data index table 440.

In FIG. 4D, the entire index table 430 may indicate an index role for the fixed message type column FIXED_MMS_COLUMNS and whether it is mapped to an actual database. For example, a column having a value of −1 in the entire index table 430 may mean a column that is not mapped to an actual database.

In FIG. 4E, the data index table 440 may include an index value for the fixed message type column FIXED_MMS_COLUMNS and an index of the corresponding column in the actual database.

In FIG. 4F, the database table 450 may include a value corresponding to each column in the actual database table.

Hereinafter, a process of obtaining data about an actual column from a virtual column will be described in more detail.

First, upon receiving a request for outputting data corresponding to the timestamp column of index 1 in the message list displayed on the screen, the cursor type and physical index value corresponding to index 1 are respectively obtained from the translation index buffer 330 of FIG. 4A. Acquire. Accordingly, 5 is obtained as the MMS and the physical index value as the cursor type.

Subsequently, in the virtual column table 410 of FIG. 4B, the fixed message column FIXED_MSG_COLUMNS obtains the name of the column mapped to MSG_COL_TIME_STAMP, that is, the column whose actual name is "time_stamp" from the physical column table 420. In this case, MMS_COL_TIME_STAMP, that is, the actual name "date" may be obtained as the fixed MMS column.

Now, the physical column table 420 examines the entire index column of the entire index table 430 corresponding to the "date" column to determine whether it is mapped to the actual database, and obtains the corresponding index value of 5. In addition, the data index table 440 obtains the index value 3 of the column corresponding to the index value 5 in the actual database.

As a result, a value corresponding to column 3 of record 5, which is the physical index of the cursor obtained from the translation index buffer 330, is returned from the MMS database. For example, the value may be 2010/10/31 of the database table 450.

5A and 5B are diagrams illustrating a data output screen of a mobile terminal according to an embodiment of the present invention.

The controller 180 provides a screen for integrated management of data available in a message transceiving application, a music playback application, and a contact management application using the conversion index buffer and column mapping information described with reference to FIGS. 4A and 4B. can do.

First, the controller 180 may generate a message type msgType, a message content msgBody, and a time stamp as a virtual column. In this case, each column may be mapped to a physical column of an actual database or may reside in a volatile region of memory 160.

The message content and time stamp, which are virtual columns, may each be a column associated with an actual physical column. The message content can be mapped to the song title in the music playback application, the name display_name in the contact management application, and the body column in the message transceiving application. In addition, the time stamp may be mapped to the date (date_added) added in the music reproduction application, the synchronization date (sync3) in the contact management application, and the date column in the message transmission / reception application.

In the case of the message type, it may be generated according to the RAM resident data structure 340 of FIG. 4A as a column that does not exist in the actual database.

5A and 5B, each item in the message list on the screen 500 displaying the message list may include the type 501 of the message, the content 502 of the message, and the time 503 at which the message was stored.

In FIG. 5A, when the user input unit 130 detects a command for sorting each item in the message list according to the message type, the controller 180 may sort each item in the list according to the message type (msgType) of the virtual column. have. For example, the data may be ordered in the order of data available in the message transceiving application, data available in the music playback application, and data available in the contact management application.

In FIG. 5B, when the user input unit 130 detects a command for sorting each item in the message list according to the message content, the controller 180 may sort each item in the list according to the message type (msg_body) of the virtual column. have. For example, the data available to each application may be sorted in ascending order of the content of the message.

6 is a flowchart illustrating a data output process of a mobile terminal according to an embodiment of the present invention.

The controller 180 may generate a translation index buffer including the index of the logical record set, the pointer type and the index of the physical record set, and store the generated translation index buffer in the memory 160 (S100). The controller 180 may convert the index of the physical record set available to the specific application into the index of the logical record set, generate a conversion index buffer, and store the converted index buffer in the memory 160. In this case, indexes included in the plurality of physical record sets may be converted into indexes of one logical record set by the pointer type of the physical record set.

In addition, the controller 180 may generate column mapping information of the logical record set and the physical record set, and store the generated column mapping information in the memory 160 (S200). In this case, the controller 180 creates a virtual column for the column that exists in the physical record set but cannot map to the fixed column of the logical record set through the nonvolatile region of the memory 160, You can register data processing functions that are called when accessing.

In addition, the user input unit 130 may detect a request for outputting data corresponding to the first column of the first index in the logical record set (S300). For example, on the screen of FIG. 5A, the user input unit 130 may detect a request for outputting data corresponding to a time_stamp column of index # 1.

In addition, the controller 180 may obtain a pointer type and a second index of a physical record set corresponding to the first index based on the conversion index buffer (S400). For example, an item corresponding to index 1 may be obtained from the cursor translation index buffer 330 of FIG. 4A. The controller 180 may obtain 5 as a cursor type and a physical index value of MMS in the item corresponding to the first index. The controller 180 may obtain column mapping information corresponding to the obtained pointer type of the item. For example, column mapping information of FIG. 4B may be obtained for an MMS which is a cursor type of an acquired item.

In addition, the controller 180 may obtain a second column mapped to the first column based on column mapping information of the physical record set corresponding to the obtained pointer type (S500). For example, based on the column mapping information of FIG. 4B, a column "date" corresponding to the column "time_stamp" may be obtained as a name of a time stamp column.

In addition, the output unit 150 may output data corresponding to the second column of the second index in the physical record set corresponding to the obtained pointer type (S600). For example, it can be seen that the physical index of the item corresponding to index 1 is 5 in the cursor translation index buffer 330 of FIG. 4A. Therefore, the controller 180 can obtain data corresponding to "timeStamp" of the record corresponding to index 5 in the database for the actual MMS. For example, the display unit 151 may output data acquired by the controller 151.
