Description

Method and device for verifying business object data

technical field

The invention relates to the field of information processing, in particular to a method and device for verifying business object data in an information system.

Background technique

During the implementation and use of information systems (especially enterprise information systems), with the continuous development of business, the original description information (that is, attribute information) of the same business object in the information system gradually cannot meet the needs of business diversity. Users often need to enrich the attribute information of original business objects. In order to avoid a large number of program code modifications caused by adding attribute information to business objects, the industry has proposed an extended attribute definition method, which is currently widely used by information systems to meet the customization needs of business objects.

The main technical principle of the traditional extended attribute definition method is: under the premise of ensuring that the existing implementation of the information system remains unchanged, the user requests the attribute information of the extended business object from the information system. The attribute information includes: basic information (attribute name, attribute type ) and auxiliary information (default value, form display, etc.). Among them, the basic information, as the essential information describing the attributes of the business object, will determine whether the extended attributes can generate the column information of the corresponding data table in the database. After the user submits a request for extended attribute information, the information system automatically generates the corresponding database fields and business object forms according to the attribute information submitted by the user. In this way, without modifying the system code, the user can use the extended attribute information to describe the business object, and enter the business object data in the business object form automatically generated by the system, and the data will be stored in the newly generated physical database table by the system .

In the above-mentioned extended attribute definition method, it is a very important process to verify the validity of the business object data input by the user. The validity of the data is verified, that is, to determine whether the business object data entered by the user is valid according to whether the business object data entered by the user can be correctly converted into the corresponding attribute type (that is, the database data type) when the attribute information is defined. However, the types and formats of business object data input by users are often diverse. Therefore, the accuracy of simply verifying the validity of business object data entered by users based on attribute types is relatively low, and it is difficult to satisfy the needs of information systems for business object data. Validity requirements.

Detailed ways

In order to improve the accuracy of the verification of the validity of business object data and meet the requirements of the information system for the validity of business object data, the embodiment of the present invention proposes a verification method and device for business object data. The main realization principles, specific implementation processes and corresponding beneficial effects that can be achieved in the embodiments of the present invention are described in detail.

In the embodiment of the present invention, before verifying the business object data input by the user according to the user request, it is necessary to set validity rules corresponding to different attributes according to the attributes of different business objects (including attribute names and attribute types). Wherein, the attribute name corresponds to the data column name generated by the extended attribute in the relational database table, and the attribute type corresponds to the data type in the relational database, such as string type (text type), number type, date type, etc.

In one embodiment, the specific process of setting validity rules is shown in Figure 1, including the following steps:

Step 101, according to the attribute type of the business object, set a validity rule template corresponding to the attribute type.

Step 102: Determine the validity rule according to the validity rule template set for the attribute type of the business object and the attribute name of the business object.

In the above step 101, different validity rule templates are set for characteristics of different attribute types. For example, when the attribute type is a number type, according to the characteristics of this type, that is, a specific value, the threshold interval of the data can be limited in the validity rule template, specifically, the maximum threshold interval of the value can be limited. value and minimum value; further, for the attribute type of the attribute type to be a number type, the precision of the value can be limited in the validity rule template, specifically, the precision and the number of decimal places of the value can be limited. When the attribute type is other types, such as string type, text type, or date type, etc., the validity rule template can be set based on the same principle as the above-mentioned setting of the validity rule template based on the number type, which will not be listed here. .

In a specific embodiment, the validity rule templates set for different attribute types can be as follows:

attribute type Field names included in the validity rule template string/text type Text length, whether the text length is fixed, including fixed strings Numeric type Min, Max, Numeric Precision, Scale date type  Start Date, End Date

It should be pointed out that the field names included in the validity rule template shown in the above table are only one way of implementing the embodiments of the present invention. In specific applications, the validity rule template can be flexibly set according to different business objects. For example, when the attribute type is a text type, the set validity rule template can include "text length", "whether the text length is fixed", Any one or combination of "including fixed strings" can also further add new fields based on the above fields, such as "exclude strings"; or, when the attribute type is text type, the set validity rule template Can be "regular expression".

After the validity rule templates corresponding to different attribute types are set through the above process, in step 102, the validity rule can be determined according to the attribute name of the specific business object and the corresponding validity rule template. For example, the fields included in the validity rule template set for the attribute type as numeric type are "minimum value" and "maximum value". When the attribute name is "age", it can be determined that the corresponding validity rule is "minimum value". Value = 0, Maximum = 150".

The validity rules determined by the above method can be used as additional attribute information of the attribute information of the business object. Specifically, the basic information in the extended attribute information in the traditional extended attribute definition method can be extended, and described in the form of the following triples (Definition) Basic information of extended attribute information:

The basic information of the extended attribute = (attribute name, attribute type, validity rule).

After the basic information of the extended attributes is submitted to the system, the system will save the information and generate relational database table data columns according to the attribute name and attribute type.

After setting the validity rules through the above process, the process of validating the business object data is shown in Figure 2, including the following steps:

Step 201, according to the attribute name and attribute type of the extended business object requested by the user, search for the validity rule corresponding to the attribute name and attribute type from the preset validity rules.

Step 202. Verify the business object data input by the user according to the found validity rules. When the verification is passed, execute step 203; otherwise, execute step 204.

In this step, before using the found validity rules to verify the business object data input by the user, first verify the attribute type of the business object data input by the user, and judge whether the business object data input by the user is consistent with the requested business object. The attribute types are consistent. If it is determined that they are inconsistent, that is, the verification fails, then directly go to step 204 or end the process.

Step 205, determine that the business object data input by the user is valid, and save the business object data.

Step 204 , request the user to re-input the business object data, return to step 202 .

In step 204, a threshold value for the number of times that the user is required to re-input may be set, and if it is determined that the number of times the user re-enters the business object data has reached the set threshold value, the process ends. Furthermore, the reason why the verification fails can be fed back to the user as a reference for the user to re-enter the business object data. It is also possible to only feed back to the user the reason why the verification failed, and then end the process. If the user wants to re-enter, he needs to re-request the corresponding service.

In the above step 202, the process of verifying the business object data input by the user according to the found validity rules is specifically: determining the validity conditions included in the validity rules, and judging whether the business object data input by the user satisfies these validity conditions, When it is satisfied, it is determined that the verification of the business object data input by the user is passed; otherwise, it is determined that the verification of the business object data input by the user is not passed. For example, the basic information of the extended attribute information of the business object requested by the user is (age, number type), and the corresponding validity rule is (minimum value=0, maximum value=150), if the business object data input by the user is 90, Then it meets the validity conditions included in the validity rule, that is, if it meets the validity conditions greater than 0 and less than 150, it is determined that 90 entered by the user is valid business object data; if the business object data entered by the user is -20, it does not meet the validity rules included The validity condition of the value is greater than 0 and less than 150, and the -20 entered by the user is determined to be invalid business object data.

When the verification method for business object data provided by the above embodiments is applied to a specific information system, the implementation process is as follows: the user submits to the information system a request to load a business object form including extended attribute information through the user interface provided by the information system ; The system accesses the database according to the user's request, and loads the basic information (attribute name, attribute type, validity rule) of the extended attribute information requested by the user into the memory, automatically generates the extended attribute entry control according to the attribute type, and Rules generate data validation controls; after the user enters business object data and submits it according to the extended attribute input controls provided by the information system, the system uses the generated data validation controls to automatically call the data validation components of the system to perform data validation. If the verification is passed, the system accesses the data access component and saves the business object data submitted by the user in the database; otherwise, the system will give a corresponding prompt to require the user to re-enter or interrupt the user request.

The embodiment of the present invention also provides a business object data verification device, as shown in FIG. 3 , the device includes: a rule search unit 301 , a verification unit 302 and a storage unit 303 . in,

The rule search unit 301 is configured to search for a validity rule corresponding to the attribute name and attribute type from preset validity rules according to the attribute name and attribute type of the business object extended by the user request.

The verification unit 302 is configured to verify the business object data input by the user according to the validity rules found by the rule search unit 301 .

The storage unit 303 is configured to save the business object data input by the user when the verification unit 302 passes the verification.

Preferably, the verification unit 302 is further configured to determine the validity conditions included in the validity rules found by the rule search unit 301, and when the business object data input by the user satisfies the validity conditions, determine the validity of the business object input by the user. Data verification passed.

As shown in Figure 4, in one embodiment, the verification device shown in Figure 3 further includes: an information feedback unit 304, which is used to feed back to the user the reason why the verification fails when the verification unit 302 fails the verification, or/ and, require the user to re-enter business object data.

As shown in FIG. 5, in one embodiment, the verification device shown in FIG. 3 further includes: a rule preset unit 305, configured to preset the attribute name and attribute type corresponding to the attribute name and attribute type according to the business object. Validity rules.

Preferably, the rule preset unit 305 is further configured to set a validity rule template corresponding to the attribute type according to the attribute type of the business object, and determine The validity rule.

Through the above-mentioned technical solution, before verifying the business object data input by the user, the present invention firstly searches the validity rules for this verification from the preset validity rules according to the attribute name and attribute type of the extended business object requested by the user. Validity rules, and verify the business object data entered by the user according to the found validity rules, and when the verification is passed, determine that the business object data entered by the user is valid, and save the business object data. Compared with the prior art that only verifies the attribute type of business object data, it can more accurately verify the validity of the business object data input by the user, and improve the accuracy of verifying the business object data and the usability of the stored business object data.

In addition, the present invention pre-sets validity rules for verifying business objects before verifying business object data, and only needs to verify according to the predefined corresponding validity rules during the verification process, thereby improving the efficiency of verifying business object data .

In addition, in the embodiment of the present invention, when the verification of the business object data input by the user fails, the reason for the failure of the verification is fed back to the user, so that the user can re-input the business object data according to the reason fed back by the system, which improves the efficiency of entering the business object data. Correct rate.
