Abstract

PURPOSE:To easily decide the state of layer structure from an optional detailed record by providing a layer start record and the detailed record with information on the layer structure. CONSTITUTION:This method is provided with a 1st means which represents the layer by outputting the layer start record forming the layer structure to a work file and a 2nd means which stores the state of elements forming the layer structure in the detailed record as information and outputs it. For example, when an inputted layer state is compared with a last layer state to judge that a new layer is inputted, setting and output processes in steps 105-108 are performed, but when not, setting and output processes in steps 11 and 112 are performed. In a step 106, the detailed record is outputted (updated) and in steps 108 and 109, the layer start record is outputted. Thus, the information on the layer structure is provided to the layer start record and detailed record. Consequently, the state of the layer state can easily be decided from the optional detailed record.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of managing data handled by an interactive system for drawing a hierarchical structure.

[0002]

2. Description of the Related Art FIG. 5 is a flow chart showing a conventional data management method of this type.

The hierarchy input in step 502 is judged in step 504. If the input is at the same level, detailed record information is output (step 505), and if not, it is determined whether or not it is a new layer (step 506). Then, if it is a new hierarchy, a hierarchy start record is output (step 507). If it is not a new hierarchy, the new hierarchy is output, and the hierarchy start record that has been output so far must be closed. The tier end records up to are output (steps 508 and 509).

When the input of the hierarchy is completed,
The hierarchy end records of all the hierarchy levels previously input are output (steps 510 and 511).

[0005]

In the above-mentioned conventional data management method, for example, when drawing, it is necessary to read an arbitrary detailed record, search for the hierarchy start record of the own hierarchy, and judge the hierarchy. is there. Then, when creating a new hierarchy, there is a drawback that the hierarchy start record and the hierarchy end record are output.

[0006]

A data management method of the present invention is an interactive system for drawing a hierarchical structure. In the process of saving the hierarchical structure in a work file, a hierarchy start record forming the hierarchical structure is stored in the work file. It is characterized in that it has a first means for expressing a hierarchy by outputting and a second means for storing the status of elements forming a hierarchical structure in a detailed record as information and outputting it.

[0007]

Next, the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention.

First, the hierarchical structure as shown in FIG. 2 is inputted from the operator console as needed (step 102), and the inputted hierarchical state is compared and judged with the previously inputted state (step 104). As a result, when a new layer is entered,
The processes of steps 105 to 108 are performed, and otherwise, the processes of steps 111 and 112 are performed.

At step 105, a layer start record indicating a new layer structure is newly present, and derivation information indicating that the layer is different is set, and at step 106, a detailed record as shown in FIG. 4B is output. (Update. Then, in steps 108 and 109, the hierarchy start record is output.

In step 111, information indicating that the layers are arranged in parallel in the hierarchical structure is set, and the detailed record updated in step 112 is output (updated). Then, a hierarchy start record indicating the hierarchy of the detail record forming the newly input hierarchy structure is set.

In step 110, a detailed record is output. Then, in step 103, it is determined whether the input is completed. As a result, the relationship between the hierarchical structure diagram shown in FIG. 2 and the output information shown in FIG. 3 is established.

The following results are obtained by this data management method.

Even when the layers are simply expressed, since it is not necessary to close each layer, the amount of information to be processed can be reduced.

When referring to arbitrary layer information, it is possible to reduce the number of accesses until the layer start record for determining the layer is accessed.

Further, when adding a hierarchy, the processing can be carried out while only considering the creation of the hierarchy start record, and when deleting the hierarchy, the processing can be realized only by deleting the beginning and end of the hierarchy to be deleted. Things are possible.

[0017]

As described above, according to the present invention, since the information of the hierarchical structure is included in the hierarchical start record and the detailed record as information, it is easy to determine the state of the hierarchical structure from any detailed record, and each hierarchical By weakening the degree of connection of structural units, it is possible to efficiently process the addition and deletion of hierarchies.
