[0001] PROVIDING APPARATUS FOR HIERARCHICAL TYPE REAL TIME CANVAS [0002]

The present invention relates to a folder type real time canvas providing apparatus, a method and a program for updating and sharing a real time real time on a web connected to the Internet to facilitate collaboration among a plurality of clients.

The existing computing environment, which relies on the independent hardware performance of each terminal according to the technological development of the computer network, is a form of cloud computing in which the service is provided according to the request of the terminal utilizing all the computing resources on the network It is evolving.

The cloud service is a service that stores a program or a document individually stored in a personal computer or a server of an enterprise in a virtual server or storage based on the Internet and drives a cloud application such as a web browser by using various terminals including a personal computer, So that the user can perform desired operations. Clients can select and use as many computing resources as they want at any time, including applications, storage, operating system (OS), and security. According to such a cloud service, clients can access a cloud network through a terminal that performs network connection and basic computation functions at any place, perform tasks requiring a large-capacity storage device and a high-performance computing resource, and receive advanced services .

However, such a conventional cloud service has been utilized close to a personal space on a network. More specifically, it is impossible for a conventional cloud service to access a server from a plurality of clients unless login information is mutually shared. Furthermore, a plurality of clients access the same server at the same time to change content in real time Most of the cases were not allowed. Therefore, it was almost impossible for a plurality of clients to collaborate in real time and intuitively on a web connected to the Internet.

Due to such a problem, in the past, there has been a limit in which a plurality of clients can only real-time collaborate through a messenger and an e-mail, or real-time collaboration by means of a video conference or the like. This conventional real-time collaboration method has a problem of insufficient quality, promptness, and intuitiveness of collaboration.

In order to solve the above problem, in the past, the personal canvas software, Microsoft's Office PowerPoint file itself was shared in a way to share with each other. Alternatively, Google presentations are configured to work collaboratively by updating the presentation files periodically using a cloud computing environment.

Korean Patent Registration No. 10-1380898 discloses a whiteboard (real-time canvas) that is updated and updated in real time on a web connected via the Internet. According to this, since the canvas is shared in real time on the web, there is no need to install separate software in the client in advance.

Korean Patent No. 10-1380898 Korean Patent Publication No. 10-2016-0070254 Korean Patent Laid-Open No. 10-2016-0070255 Korean Patent Laid-Open No. 10-0094281 Korean Patent Publication No. 10-2012-0090386

However, when users were using the canvas and had to organize their thoughts into one canvas, there was always a shortage of space. Also, the user's idea is mainly tail-tailed. In other words, according to users' experience, several ideas are hierarchically organized.

Microsoft Office PowerPoint, and Google Presentation were configured to add pages when there was not enough space on the canvas. If we needed a new canvas, we were going to add a page and move the screen output to that page.

In addition, the virtual canvas information table according to one embodiment of the present invention can be configured to have a one-to-many relationship that can be connected to at least one canvas information table.

According to the virtual canvas information table (AliasCanvas) according to an embodiment of the present invention, when the contents of the original canvas are changed, an effect that can be immediately applied to the virtual canvas also occurs. When a data structure is configured such that the canvas information table of another original canvas is included in the canvas without using the virtual canvas information table, when the contents of the original canvas are changed by a specific user, Lt; / RTI > In addition, according to the virtual canvas information table according to the embodiment of the present invention, there is also an advantage that the user can freely control the authority of the canvas. In the embodiment of the present invention, the definition of the simple copy paste of AliasCanvas and the canvas is differently defined, thereby allowing the user to manage the authority more precisely.

FIG. 12 shows an object information table (CanvasData) according to an embodiment of the present invention. As shown in FIG. 12, the object information table is a table for a minimum unit of objects stored in the canvas. The object information table may include a subType field such as postit-type object, postit-type object, comment-type object comment, and image-type object image. In addition, a unique key id of the canvas can be included to define the canvas to be stored.

The object information table may include fields such as width, height, scaleX, scaleY, left, and top so that the position and size of the object can be adjusted. In addition, the object information table according to an embodiment of the present invention can be configured to have a one-to-many relationship that can be connected to at least one canvas information table.

According to an embodiment of the present invention, a canvas object that is a sub-canvas can be stored in an object information table (CanvasData). 13 is an illustration showing a display form of a canvas object according to an embodiment of the present invention. As shown in Fig. 13, the canvas object can be displayed in a folder form. When the canvas object is displayed on the display in the form of a folder, the object information table may include a thumbnail field so that the information stored on the original canvas is expressed in a thumbnail form.

FIG. 14 is a table relationship diagram showing the relationship between an object information table, a canvas information table, and a virtual canvas information table according to an embodiment of the present invention. As shown in FIG. 14, the object information table may include an alias field indicating id of virtual canvas information to store the canvas object. That is, the canvas object can be configured to reference the original canvas with virtual canvas information, which is basically an alias canvas, rather than canvas information, which is the original canvas. According to the embodiment of the present invention, the canvas object can be performed with a small data size by referring to the virtual canvas information table without referring to the canvas information table which is the original canvas. Thus, even when the canvas information in which the canvas object exists is retrieved, the speed at the client is improved.

In addition, the object information table in which the canvas object is stored may include a canvasid, which is a unique id value of a reference original canvas, and an alias, which is a unique id value of a reference canvas. Clients can request access to the original canvas path via canvasid and aliasid. Each canvas object is stored in the form of an object information table, and the effect of enabling access to another canvas in the canvas is generated.

FIG. 15 illustrates a canvas tree structure of a canvas object implemented by an object information table according to an embodiment of the present invention. As shown in FIG. 15, the canvas and canvas objects can be configured as a tree structure by storing the canvas object in the object information table, and the effect of inheriting the authority of the parent canvas upon accessing is generated.

For example, if Canvas A is configured as a subfolder in Canvas A, and Canvas A is granted Modify permission to User 1, canvas B, which is a sub-concept of Canvas A, . However, if canvas B is granted modification rights to User 1, canvas A, which is the upper concept of canvas B, can not be modified by User 1 because of the vertical relationship of the tree structure. A separate authorization request will be required. This may include viewing rights, proposal rights, etc., as well as modification rights.

As a result, according to an embodiment of the present invention, when a request to create an object that refers to the second canvas in the first canvas is received at the transmitting and receiving unit in the first client having the modification right, the canvas module transmits information about the second canvas And the object module can be configured to generate second canvas object information that is information on the object that refers to the second canvas.

The second canvas object information includes first canvas reference information (" _id " according to Figs. 6 to 11) and second canvas information, which are information that refers to the first canvas information, (&Quot; canvasid " or " aliasid "

For example, when an output request for the first canvas is received from the first client or the second client, the canvas module transmits the first canvas information to the transmission / reception unit, and the object module transmits the second canvas object information to the transmission / Lt; / RTI >

When an output request for the second canvas object is received from the first client or the second client, the canvas module transmits the second canvas information to the transmission / reception unit so that the second canvas object of the first client or the second client A second canvas may be output on the display of the device requesting the output.
