Abstract

PURPOSE:To automatically adjust attributes of related items at the time of changing the attribute of one item by holding information of relations between the item and the other items in a dictionary to borrow attributes of the other items. CONSTITUTION:When items have such relations that the number of digits of the attribute of 'total amount of money' is equal to (the number of digits of the attribute of 'amount of money') +2, information indicating that 'total amount of money' is obtained by adding 2 to the number of digits of the attribute of 'amount of money' and a pointer to 'amount of money' are set to the attribute part of 'total amount of money'. When the number of digits of the attribute of 'amount of money' is changed, the number of digits of 'total amount of money' is automatically adjusted and expanded as (the number of digits of 'amount of money')+2 when an attribute information expanding part 2 expands a source program. Attributes are borrowed from two items 'unit price' and 'quantity' to adjust the attribute of 'sales' in such relations that the number of digits of the sum of these two items is equal to the number of digits of 'sales'. Thus, an influence upon the program accompanying the change of attributes is completely managed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a computer software development support system, and particularly to a terminology management dictionary thereof.

(Prior art) Conventionally, this type of terminology dictionary focuses on a certain item in a program, retrieves attribute information from the dictionary according to the name of the item or the format of the item, and uses the attribute information as the attribute of the item. Only the method of expanding into a program was known.

(Problem to be Solved by the Invention) In the conventional dictionary system described above, attributes are managed independently for each item. This method has the disadvantage that the relationship in which the other attribute is also affected in some cases is not understood, and the impact on the program due to attribute changes is not completely managed.

An object of the present invention is to provide a dictionary system with an attribute-related information section that shows relational information between a certain item and another 100 entries, and to chain attribute information in items that are shown to be related by the related information. The object of the present invention is to provide an attribute borrowing method for a dictionary system that eliminates the above-mentioned drawbacks by extracting the attributes, and is configured so that the influence on the program due to attribute changes can be completely managed.

(Means for Solving the Problems) The attribute borrowing method in the dictionary system according to the present invention is configured to include a dictionary section and an attribute information expansion section.

The dictionary section includes an attribute related information section for storing related information between a certain item and another item, a pointer for extracting the attribute information of items indicated as related by the instructions and related information in a chain. It is prepared.

The attribute information expansion section reads the source program, and when a reference is made to the dictionary section, extracts the attribute information from the dictionary section and expands it into the attribute program, but when an item is defined to borrow an attribute, it follows the pointer. This is to extract the attributes of the borrowing source and expand the determined attributes according to the instructions of the attribute related information.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of an attribute borrowing method for a dictionary system according to the present invention.

In Figure 1, 1 is a dictionary section, 2 is an attribute information expansion section, and 3 is a dictionary section.
4 is a source program storage means, and 4 is an expanded program storage means.

In Figure 1, the dictionary part 1 has an item for each item, and each item has an item name for accessing that item, and if the attribute of that item is different from the attribute of another item. If the item is borrowed from the item, an attribute related information section indicating the relationship and a voice/retrieval section for extracting the item from which the item was borrowed are included.

The attribute information development section 2 reads the source program from the source program storage means 3. If there is a citation to the dictionary section 1, the attribute information expansion section 2 extracts the attribute information from the dictionary section 1 and expands it into the attribute program in the attribute program storage means 4. However, at that time, if the item is defined in the dictionary as borrowing an attribute, follow the above pointer to retrieve the borrowing source attribute, synthesize the attributes according to the instructions from the attribute related information section, and create the attribute of the item. Expand this as

FIG. 2 is an explanatory diagram showing an example of attribute management performed by the apparatus of FIG. 1.

In Figure 2, if the attribute of 1 total amount l must be the number of digits of the attribute of 1 amount l + 2 digits, then in the attribute part of 1 total amount l, 1 total amount l must be 1 Amount l
The information that it can be obtained by adding the number of attribute digits + 2 digits and a pointer to one amount I are set. When the number of digits in one amount io attribute is changed, when the attribute information development unit 2 develops the source program, the number of digits in one total amount I is automatically changed to one amount l.
It is adjusted and expanded to the number of digits + 2 digits.

Similarly, the attribute of one sales amount I is adjusted by borrowing the attributes from the two items of one unit price l and one quantity l, and maintaining the relationship that the number of digits is the sum of the number of digits.

(Effects of the Invention) As explained above, the present invention maintains related information between a certain item and other items in the dictionary, and enables the borrowing of attributes of other items. When an attribute is changed, the attributes of related items are also automatically adjusted, which has the effect of improving program modification efficiency and safety.
