Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a data processing device primarily intended for use in the database field.

BACKGROUND OF THE INVENTION In recent years, the spread of databases has been remarkable, and the formats of the data being handled have also become more complex. Above all,
Applications for processing large amounts of data with complex relationships between individual pieces of data are increasing in various fields, including the field of artificial intelligence.

Relational databases are widely used as a form of implementation of general-purpose data processing devices that handle relationships between such large amounts of data.

The operation of a data processing device that implements a conventional relational database will be described below with reference to the drawings.

FIG. 7 is a diagram showing event information such as an exhibition in a relational database in a conventional data processing device. 7th
In the representation in the figure, the relational table "Event" represents the relationship between the event name, venue, and admission fee, and the relational table "Event Venue" represents the relationship between the event venue and its address.

For the event information expressed in the relational database as described above, for example, if you want to search for the address where the "Microcomputer Show 87" will be held, first select "Event Name - Microcomputer Show “
Obtain the event location "Tokyo OO Center" for the data in the row "87", and then select "All venue names -" from the related table "Event Venue".
Obtain the data for the address ``Heiwajima, Ota-ku, Tokyo'' for the row that is ``Tokyo oO Center''.

Problems to be Solved by the Invention However, with the data representation method described above,
Prior to data entry, the parties involved and the data attributes expressed in the relationship table must be strictly defined, and when searching, users will not be able to perform a search unless they know these definitions, placing an extremely heavy burden on users. Furthermore, when data with characteristics that deviate from this definition occurs, it becomes difficult to manage as it requires either redefining and re-creating the relational tables that have already been created, or increasing the number of relational tables. There was a problem.

For example, for the event information database,
If data such as "Event name - 〇〇〇〇 academic conference" is generated, in which the admission fee differs depending on the type of visitor (member, non-member, student member), a new A new relationship table "Admission Fees" must be defined and the admission fee data in the relationship table "Events" must be moved to the new relationship table "Admission Fees."

The present invention has been made in view of the above problems, and is a data processing device that has a simple configuration and is capable of flexibly storing and searching a large amount of data with a complex structure in which the relationships between individual pieces of data are structured. It provides:

Means for Solving the Problems In order to solve the above problems, the data processing device of the present invention provides an entity name of a first entity, one or more value sets representing the meaning or content of the entity, and the values. a plurality of simple data storage units that store a piece of simple data based on a set of one or more attribute name sets that describe the meaning or content of the entity; and a plurality of the simple data storage units; a single data management section that manages a plurality of pieces of single data by referring to or editing each piece of single data in the data storage section; and a single data input that inputs the single data into the single data storage section through the single data management section. a unit data search unit that searches for unit data by specifying all or part of the entity name, attribute name set, and value set of the unit data for the unit data management unit; and a structure description data search unit that searches for data. Each piece of data is stored as unit data by a set of "entity name, attribute name set, and value set," and a plurality of unit data is managed by the unit data management unit.

Effect of the present invention With the above-described configuration, data can be input without strictly defining the data structure or data attributes in advance, and even if the nature of the data changes during data input,
You can continue to input data without making any changes to the data that has already been stored. Furthermore, data searches can be performed using clues such as entity names, attribute name sets, and value sets.

Embodiment Hereinafter, a data processing apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a configuration diagram of a data processing device in an embodiment of the present invention. 1st
In the figure, 1 is a single data storage section, 2 is a single data management section, 3 is a single data input section, and 4 is a single data search section.

The operation of the data processing apparatus configured as described above will be described below with reference to FIGS. 1, 2, 3, 4, 5, and 6.

FIG. 2 shows a data processing device according to an embodiment of the present invention.
This is a diagram showing the general form of the single data storage format in the single data storage unit 1.In Figure 2, the single data is written in left parentheses "(", followed by the entity name, one Al ?J[B A set of attribute names consisting of attribute names connected with hyphens "-", a value set consisting of one or more values enclosed in left and right parentheses, and finally a right parenthesis ")" are stored. Figure 3 is a specific example of single data.
○The data shows that the center is

The unit data is input from the unit data input section 3 in accordance with the format shown in FIG. The unit data input from the unit data input unit 3 is sequentially stored in the unit data storage unit 1 via the unit data management unit 2.

FIG. 4 shows the contents of the database managed by the unit data management unit 2 after data having the same contents as those shown in FIG. 7 have been stored in the unit data storage unit 1 as described above.

When adding data on the venue, admission fee, and venue address regarding "event name - 〇〇〇〇 academic conference" to the database shown in Figure 4, the data entry section 3 inputs the five individual data shown in Figure 5. After inputting data and sequentially adding and storing data to the unit data storage unit 1 through the unit data management unit 2, data with the same content as shown in FIG. 8 is stored in the unit data storage unit 1 as shown in 0 or more. FIG. 6 shows the contents of the database managed by the management section 2.

With respect to the database created as described above, the unit data search section 4 performs the following search on the unit data management section 2.

For example, in response to a search such as "Display the address where the Microcomputer Show 87 will be held," first, enter "Entity - Microcomputer Show 87" in the unit data management unit 2, and enter "Location" in the attribute name set. Search for single data that has
Get the value "Tokyo OO Center". Next, the unit data management unit 2 is searched for unit data whose attribute name is ``Address J'' in ``Entity - Tokyo OO Center,'' and the value ``Heiwajima, Ota-ku, Tokyo'' is obtained.

As another example, for a search such as "Display the admission fee for Microcomputer Show °87," the unit data management unit 2
``Entity - Microcomputer Show ° 87'' is searched for single data with ``admission fee'' in the attribute name, and the value ``free'' is obtained. On the other hand, rooo.

For the search "Display admission fees for academic conferences," the unit data management unit 2 is searched for single data with "entrance fees" in the attribute name for "entity - 〇〇〇〇 academic conferences." ,
Attribute and value pair "(Members 8,000 yen) (Non-members 1,200 yen)
0 yen) (student member 4000 yen).

On the other hand, if the attribute name is not known, for example, the unit data management unit 2 is searched for the entity name and attribute name of "value-Tokyo XXX Center" to obtain (microcomputer show °87 venue).

In the upper part, the format for storing single data in the single data storage unit 1 is expressed using left and right parentheses and a hyphen as shown in Figure 2, but other symbols may be used or the data may be connected using pointers.
