(B) directory reading means for reading out the contents of the directory file; (C) deletion determining means for determining deletion of article data based on the data name and deletion mark read by the directory reading means; (D) Only article data that is not deleted can be accessed,
It is equipped with article recovery means for erasing deleted article data, and (E) processing activation means for automatically activating article data deletion at the start of a day's work.

〔Example〕

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

FIG. 1 is a block diagram of one embodiment of the present invention.

The article data deletion method shown in FIG. 1 includes a storage means 100 for storing an index section directory file 50 and an actual data article file 60 as article data, and a directory reading means 20 for reading out the directory file 50.
Based on the data name 52 and deletion mark 53 read by the directory reading means 20, the deletion determination means 30 determines whether or not the article data 62 of the article file 60 should be deleted. Deletion article recovery means 40. Consists of processing activation means 10 that automatically activates article data deletion at the start of business on the first day.

Next, the operation will be explained.

By using the article file deletion method of the present invention to recover article files whose retention period has not expired at the start of daily operations of the newspaper production system, articles whose retention period has passed without actually deleting the article files can be deleted. The method for deleting files is shown below.

In FIG. 1, first, the directory reading means 20 is started by the processing starting means 10.

Then, the directory reading means 20 reads the data name 52 and deletion mark 53 from the directory file 50 every 100 blocks, and repeats the reading process until the last block. In addition, the read contents are sequentially
It is passed to the deletion determination means 30.

Here, the contents of the directory file 50 will be explained.

The directory file 50 is a file that serves as an index section for article data in a computer editing system for newspaper production. As an initial value of the directory file 50, "0" is stored in all blocks corresponding to the maximum number of registered articles (for example, 100,000 articles).

Each directory block includes a block number 51 for indexing, a data name (iD>52) for accessing article data from the outside, a deletion mark 53 for identifying whether the article should be saved or deleted, and article data. It is composed of a data block chain 54 for storing the storage location of 62. Among them, the data name (iD) 52 includes a newspaper publication date for determining the storage period. , the deletion mark 53 stores "0" if the article has been deleted, and stores "1" if the article has been saved.

By the way, in the deletion determination means 30, first, the deletion mark 5
If the content of 3 is "0", the value of "-1" is notified to the article recovery means 40 as data to be deleted. Further, if the content of the deletion mark 53 is "1", next, the newspaper publication date in the data name (iD) 52 and the date in the system are compared, and the difference is determined in advance by the deletion determination means 30. Determine whether the number of retention days defined in the file has been exceeded. If the determined result exceeds the retention period, the article recovery means 40 is notified of the value of "-1" as the data to be deleted, and the deletion mark 53 in the corresponding directory - Pro 7 indicates that the article is to be deleted. If the storage number of days has not exceeded, the article recovery means 40 is notified of the value of 0 as the data to be stored, and the contents of the corresponding directory block are passed.

Further, the deletion determining means 30 writes the updated contents of the deletion mark 53 to the directory file 50 when the processing for the directory block passed from the directory reading means 20 is completed.

In the article recovery means 40, if the value notified from the deletion determination means 30 is "-1", the corresponding article data is deleted and no processing is performed.

If the notified value is "0", the corresponding article data is saved, and the article recovery process is performed.

Here, various tables in the storage section used by the article recovery means 40 will be explained.

First, the ID index table 70 is accessed from the article data 6 from outside.
It is used when accessing 2, and the data name (
iD) 52, block number 51, and data block chain 54 are stored in association with each other.

Next, the directory file pit map table 80
is provided to manage the usage status of the directory file 50, and corresponds to block number 51. If it is in use, "1" is stored, and if it is unused, "0" is stored. .

Further, the article file bitmap table 90 is provided to manage the usage status of the article file 60, and corresponds to the block number 61. If it is in use, "1" is stored, and if it is unused, "1" is stored. , "0" are stored.

The initial values in the above various tables are all stored as "0".

By the way, when recovering an article, first register the block number 51, data name (iD) 52, and contents of the data blockchain 54 of the corresponding article data in the ID index table 70, and make it accessible from the outside. .

Next, the directory file pit map table 80
In the place corresponding to block number 51, °゛1'
” is stored and the corresponding directory block is in use.

Finally, "1" is stored in the article file bitmap table 90 at the location corresponding to the block number 61 in the article file 60 stored in the data blockchain 54, indicating that the corresponding article data block is in use. state.

The article data deletion process ends when all directory files 50 are read and written.

When the process is completed, if the content of the location corresponding to each block number in the directory file pit map table 80 and the article file bit map table 90 is "0", the directory file 50 and the actual external article medium's directory file 50 and This means that the corresponding block in the article file 60 is unused, and as a result, the article whose retention period has expired is deleted.

In this way, by automatically deleting article data at the start of each day's work, the operator does not have to perform the work at the end of each day's work, and the data name and deletion mark of the article data can be used to automatically delete article data. There is no need for the operator to give an individual instruction by determining deletion of .

Furthermore, by separating article data into a directory file for the search section and an article file for actual data, processing performance can be greatly improved.

〔Effect of the invention〕

As explained above, the present invention eliminates the need for the operator to delete article data at the end of the day's work by automatically deleting article data at the start of the day's work. By determining deletion of article data based on the data name and deletion mark of the data, there is an advantage that the operator does not need to give individual instructions.
