【Example】

Example 1. The data management device of the present invention will be described below with reference to FIG. The same elements as those shown in FIG. 5 are designated by the same reference numerals and the description thereof is omitted. In the figure, 5
Is an updated design drawing data storage means. This is composed of update data storage means 5a for the set time and update data batch storage means 5b. The updated drawing data storage means 5 is based on the already-designed drawing data 4d transferred from the design drawing data storage means 4A via the server 1 and various information 2
With reference to a to 2d, only the updated design drawing data 5d which is updated by making a design change in the design terminal 3 is stored. The set time update data storage means 5a stores data updated at preset time intervals, and the set time update data storage means 5a updates a plurality of set times at set time intervals. The data is accumulated and stored in the update data batch storage means 5b. Therefore, only the already-designed drawing data up to the previous day is stored in the design drawing data storage means 4A.

Next, a data management method by the data management device will be described with reference to FIGS. First, when the drawing data is updated, as shown in FIG. 2, every time a change occurs in the drawing data, the updated design drawing data is stored in the update data storage means 5a for the set time. In this case, for example, every one hour, the update data storage means 5 for this set time
The data is stored in a, and this data is transferred to the update data batch storage means 5b every one hour. Then, the updated design drawing data for several generations of several hours are collectively transferred to the design drawing data storage means 4A to update the design drawing data. That is, the updated design drawing data generated during the design work is not the drawing data storage means 4A but the update data storage means 5 for the set time of another file.
stored in a. Therefore, data writing during designing is performed only to the updated design drawing data storage means 5. Then, the stored data is transferred to the update data batch storage 5b every time a set time, for example, one hour has passed, and the data for a plurality of generations is accumulated and managed here. In the drawing data update process, first, a copy of the designed drawing data having the contents up to the previous day is stored in a separate file as the backup means 4a. Then, the data of the updated design drawing data storage means 5 is transferred to the design drawing data storage means 4A, and the contents of the drawing data storage means 4A are collectively updated by batch processing.

Next, when the drawing data is restored in the event of a failure, first, as shown in FIG. 3, the contents (the contents of the previous day) stored in the backup means 4a are copied to the design drawing data storage means 4A. . At this point, the contents of the design drawing data storage unit 4A are the contents of the previous day. Then, the data stored in the update data batch storage means 5b is transferred to the drawing data storage means 4 in order for each time to update the drawing data. In this restoration processing, the updated design drawing data (for one hour) stored in the updated data storage means 5a for the set time is not used at all. Therefore, even if the updated design drawing data is damaged during the design work, the updated design drawing data for one hour at maximum is invalidated, and the updated design drawing data up to one hour ago can be recovered. In addition, it will be possible to perform fine-grained restoration in units of hours.

The data management apparatus according to the present invention has a file structure for storing design drawing data (existing design drawing, updated design drawing data), a design drawing data storage means 4A and a backup means 4a (duplication of the design drawing data storage means). )
A set time update data storage means 5a (update data generated during a predetermined set time by design work is accumulated), and an update data batch storage means 5b (set time update data storage means 5a). (The update data for a plurality of set times is stored) and each is configured by a physically different storage device. Therefore, since the writing process to the design drawing data storage means 4A does not occur during the design,
The frequency of breakage of the design drawing data storage means 4A is reduced.
Further, by storing the data in the physically different storage means in a distributed manner, it is possible to prevent all the data from being damaged at the same time.

Example 2. In the data management method of the present invention, the updated design drawing data generated by the design work is stored in the update data storage means 5a for the set time during the preset time (for example, 1 hour), and the set time is set. Every time elapses, the updated design drawing data for the set time is transferred to the updated data batch storage means 5b. And, for example, 1
With the time as one generation, the updated design drawing data of a plurality of generations is transferred from the update data batch storage means 5b to the design drawing data storage means 4A, for example, in order of earlier time, and the data is updated. Therefore, when a system failure occurs during design work, the update data storage unit 5a for the set time during which the writing process is performed is most likely to be damaged, but the update data storage unit 5a for the set time is within the latest one hour. Only the updated design drawing data is stored, and the drawing data can be restored to the state of one hour before even in the worst case.

After the design work is completed, the design drawing data is updated. This is to copy the contents of the design drawing data storage means 4A to the backup means 4a, and then from the updated drawing data batch storage means 5b stored for each set time unit, sequentially set the data for each set time unit in order of each hour. Then, the drawing data is transferred to the design drawing data storage means 4A to update the drawing data. Therefore, during the above update process, a system failure occurs, or the update process fails for some reason,
Even if the design drawing data storage means 4A is damaged, the backup means 4a can immediately restore the data. Further, since the update data is stored in the update data batch storage means 5a for generation management of the update data every hour, it is possible to perform fine restoration in hourly units (state at 1:00 pm on the day).

In the embodiment, the update drawing data storage means 5 is provided in the database 2 of the server 1, but it may be provided for each design terminal 3.

[0023]

According to the first aspect of the present invention, since the design drawing data storage means and the updated design drawing data storage means are separately provided, the already-designed drawing data and the updated design data when the system fails during the design work. It is possible to prevent a situation in which the drawing data is both damaged.

According to the second aspect of the present invention, the update design drawing data storage means is constituted by the update data storage means for the set time and the update data batch storage means, and is set as a storage device which is most accessed and is prone to failure. By providing the update data storage means for the set time for storing the update drawing data at every predetermined time, it is possible to minimize the damage to the update drawing data.

According to the method of claim 3, the updated drawing data is stored in the updated drawing data storage means, and the updated drawing data is transferred to the drawing data storage means to update the data. It is possible to recover the updated design drawing data.

According to the method of the fourth aspect, since the updated design drawing data is stored separately for each set time, it is possible to perform fine restoration in time units.
