DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system capable of interactive data operation, for example, converting a data operation history by a user into a form that can be displayed, edited, and reused, and provides the user with the data. The present invention relates to a visualization device for an operation sequence to be presented.

[0002]

2. Description of the Related Art The conventional method converts an operation sequence of data into a programming language in a text format. An operation performed by a user using a keyboard or a mouse is converted into a command in a programming language, and the result is presented to the user in an editable form.

[0003]

When a user interactively operates data, a mouse, which is a pointing device, is mainly used. In the conventional method, since the operation sequence is converted into text, a keyboard is mainly used for the editing work. For this reason, there is a problem that a device used at the time of data operation and a device used at the time of editing the operation sequence are different, and the burden on the user increases.

[0004] In a text-based programming language, the time course of an operation is expressed in one dimension. For this reason, when the user cancels the operation: 1. Canceled operations are not displayed. The statement that the operation was canceled was displayed in the same column as the regular operation. In the former case, there is a problem that the canceled operation history cannot be reused. In the latter case, there is a problem that the legitimate operation and the canceled operation are displayed in the same column, so that the readability of the program is reduced and the reuse becomes difficult.

[0005]

According to the operation sequence visualization operation of the present invention, an operation interpretation unit for converting an operation performed by a user into an instruction, and the instruction converted by the operation interpretation unit are stored as an operation sequence. An operation sequence storage unit, an operation sequence conversion unit that converts the operation sequence into a valid graph, an operation sequence display unit that displays the valid graph in an editable form, and a re-execution of the operation sequence based on the valid graph And an operation sequence execution unit that performs
The effective graph is the data and data to be operated.
The operation added to the data is regarded as a node, and the time of the node
It is characterized in that the target change is an arc.

[0006]

[0007] Further, the present invention is characterized in that the operation canceled by the user in the effective graph is a branch.

According to the operation sequence conversion method of the present invention, an operation sequence performed by a user on data is converted into an effective graph by the following method.

1. The data to be operated is the start node. The operation performed on the data becomes the next node,
Data and operations are connected by an arc. Hereinafter, each time an operation is performed, a node representing the operation is added to the graph one after another. When the operation ends, a node representing data at the end of the operation is added to the end of the effective graph.

[0010] 2. When the user cancels the operation and performs the operation again, a node indicating the new operation is added after the node indicating the operation immediately before the operation is canceled. The canceled operation is represented as a branch of the effective graph.

Further, this effective graph is displayed in a form that can be edited and reused in the following manner.

1. Display method (a) A node indicating data is displayed as an appropriate figure.

(B) The node indicating the operation is displayed as a character string obtained by converting the operation into an instruction.

(C) The arc is displayed as a straight line.

2. The valid graph can be edited as follows using a pointing device such as a mouse.

(A) Deletion of arc and reconnection (b) Deletion of node is possible

[0017]

According to the operation sequence conversion method and display method of the present invention: The operation sequence is converted into a valid graph, and the valid graph can be edited using the same device as the data operation, thereby reducing the burden on the user.

2. Since the operation canceled by the user is expressed as a branch of the effective graph, the canceled operation can be effectively reused.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of the configuration of the apparatus of the present invention. The data operation environment (5) is an environment for interactively operating data. An operation interpreting unit (7) converts an interactive operation performed by a user using a pointing device or the like into a command for data.

The converted instruction is applied to the data by the instruction execution unit (6).

FIG. 2 is an example of an interactive data manipulation environment. It is possible to manipulate tabular data in the following ways.

1. Rows, columns, selected using the mouse
1. Perform delete, insert, copy, and paste operations on the rectangle using the buttons arranged on the left side of the screen. For each element, a value is input from the keyboard. The operation sequence storage unit (4) stores the operation sequence converted into an instruction by the operation interpretation unit (7). The operation sequence conversion unit (3)
The operation sequence stored in the operation sequence storage unit (4) is converted into an effective graph (9) by the following procedure.

1. 1. The data to be operated is set as the start node. 2. Let the operation added to the data be a node. 3. Draw an effective arc from the start node to the operation node. Hereinafter, each time an operation is added, an operation node is added.
4. Draw an effective arc from the previous operation node The operation canceled by the user is converted into a branch of the effective graph. For example, when the user operates in the order of operation 1 → operation 2 → operation 3 → cancel → cancel → operation 4, an effective graph as shown in FIG. 3 is generated.

The operation sequence display section (2) presents the effective graph to the user in an editable form. At this time, a node indicating data is displayed as a picture, and an operation is displayed as a character string indicating an instruction. The displayed effective graph can be edited as follows using a pointing device such as a mouse.

1. Replacement of arc 2. 2. Delete and copy nodes Partial extraction of effective graph The operation sequence execution unit (10) re-executes the operation sequence based on the effective graph edited by the user.

According to the above procedure, the operation sequence can be converted into a valid graph, edited by the user, and reused.

[0028]

As described above, the operation sequence visualization device of the present invention displays the sequence of operations performed by the user on the data, the start and end nodes of the data to be operated, and the added operations. Is an intermediate node, which is converted into an effective graph connected by an arc in a temporal order, and presented to the user in a form that can be edited and reused. The operation canceled by the user is expressed as a branch of the effective graph.

As a result, 1. The operation sequence is converted into a valid graph, and the valid graph can be edited using the same device as the data operation, thereby reducing the burden on the user.

2. Since the operation canceled by the user is expressed as a branch of the effective graph, the canceled operation can be effectively reused.

This has the effect of:
