Description
Technical Field
The present invention relates to the field of data storage and data management, and in particular, to a method and an apparatus for dynamically expanding data fields.
Background
Data storage and management is important in all industries. People usually use data tables to store various data, and for management convenience, data of different attributes of the same object is usually stored in a large table or a plurality of small tables which are split and associated with each other.
In the prior art, since data storage and management standards established by each region or organization may be different, it is common for developers to develop a data (e.g., directory data) storage and management system specific to each region or organization for specific standards of each region or organization, for example, the standards including data content (e.g., data fields to be stored), attributes of fields or field values (e.g., formats of the fields or field values, whether the fields are open to the society or not, etc.). That is, the existing data storage and management system is developed in a manner of being purposefully developed according to a specific standard of a specific region or organization, and if standards established by different regions or organizations are different, developers need to develop different data storage and management systems according to different standards. In addition, the standards of the same region or organization are not constant, and may be adjusted or modified at a later stage, and at this time, the developer needs to develop again according to the changed standards. Therefore, the data storage and management system designed and developed by adopting the prior art has low reuse degree and difficult post-maintenance.
In order to solve the above problems, a new technical solution needs to be proposed.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Fig. 1 shows, by way of example, a schematic flow diagram of a method for dynamically extending data fields according to the invention.
As shown in the solid line box of fig. 1, the method for dynamically extending data fields according to the present invention includes:
step S102: constructing a basic information table (i.e., table 3 in fig. 3 c);
step S104: an extended information table is constructed and,
the basic information table is used for storing data of basic information fields of the objects, and the extended information table is used for storing data of extended information fields of the objects.
For example, one extended information table (corresponding to one template) may be constructed for each different data storage and management standard, so that extended data and basic data satisfying the different data storage and management standards are independent from each other and do not affect each other.
For example, the data of the extended information field (i.e., the template data) may be personalized by a developer according to user requirements. For example, the data of the extended information field may include a combination of the basic information field data (e.g., a combination including a direct concatenation of different basic information field data, etc.).
For example, all basic information fields corresponding to data that needs to be stored and managed and needs to be expanded (e.g., data related to a directory) can be obtained by the following exemplary steps — i.e., the database fields are sorted:
s1: the method comprises the steps of analyzing SQL texts uploaded by users, analyzing SQL text data, and generating information of basic fields (namely, the basic information fields), wherein original data (namely, original field attributes) corresponding to the basic fields are called basic metadata, and the basic fields and the basic metadata are public fields contained or used when field expansion in different forms is carried out according to different data storage and management standards (for example, field expansion is carried out by defining different expansion information tables or templates as described below) and field attributes of the public fields.
Optionally, as shown in the dashed box of fig. 1, the method for dynamically extending a data field according to the present invention further includes:
step S106: construct an extended mode description table (i.e., Table 1: template table in FIG. 3 a);
step S108: an extended configuration table (i.e., table 2 in figure 3 b: template configuration table) is constructed,
the extended mode description table is used for storing data comprising the following fields: the extension mode index field and the extension mode name field, and the extension configuration table is used for storing data comprising the following fields: the extended mode index field and the extended information field index field, and the extended information table further comprises the data of the following fields: the object index field of the basic information table is combined with the index field of the extended information field to uniquely identify the data of the extended information field.
For example, the extended metadata (i.e., the extended field attributes) corresponding to a selected extension may be obtained from the selected extension (e.g., one-to-one with the data storage and management criteria and the extended configuration table described above) by one of the following example steps:
s2: the selected template (i.e., the selected expansion mode, or the selected data storage and management standard, or the selected expansion configuration table) is obtained, and according to the specific configuration information (i.e., the data records in the table) in the selected expansion configuration table corresponding to the selected template, the expanded metadata conforming to the currently selected template is generated based on the basic metadata generated in the step S1.
For example, the base metadata may be stored in a base information table, the extended metadata corresponding to the template may be stored in an extended information table (see table 4 in fig. 3 d), and a data value (value) of one extended information field may be uniquely associated and identified with an object index field column _ base _ info _ id of the base information table and an index field template _ define _ info _ id of the extended information field.
S3: the selected template (i.e. the selected expansion mode, or the selected data storage and management standard, or the selected expansion configuration table) is obtained, and according to the specific configuration information (i.e. the data records in the table) in the selected expansion configuration table corresponding to the selected template. Alternatively, the extension field that conforms to the selected template may also be generated by a combination of base fields (e.g., by direct concatenation of different base fields, etc.).
For example, the extension data corresponding to the extension field may be stored in an extension information table (see table 4 in fig. 3 d).
In steps S2 and S3, since the template _ define _ info _ id corresponding to each template exists uniquely, the extension data of the respective templates stored in the same extension information table are also independent of each other and do not affect each other.
Optionally, as shown in the dashed box of fig. 1, the method for dynamically extending a data field according to the present invention further includes:
step S110: providing an extended configuration GUI to an administrator for defining or modifying field attributes and attributes of the field attributes of the extended configuration table,
wherein the field attribute comprises at least one of: a field name, a field description or remark, a field type, a base length, an extension length, an identifier indicating whether to open to the society, a presentation type, a presentation format, a remark, a resource format, an information resource classification, a sharing type, an open type, a unique field, a test column,
the attributes of the field attribute include at least one of: chinese name, English name, data type, data length, decimal point location, source association, pull-down value, default value, operation.
Optionally, the value of the field attribute and the value of the attribute of the field attribute are selected by the administrator from a plurality of pull-down selection items in a pull-down list corresponding to the field attribute and the attribute of the field, respectively.
Optionally, as shown in the dashed box of fig. 1, the method for dynamically extending a data field according to the present invention further includes:
step S112: and providing different user access GUIs according to the selected expansion mode so that the user can execute the expansion access operation aiming at the expansion information table and the basic information table corresponding to the selected expansion mode.

In order to make the technical solutions according to the present invention more clearly understood by those skilled in the art, the following description will be given with reference to specific embodiments.
Fig. 3 a-3 d exemplarily show the structure of 4 tables that can be used according to the above-described solution of the present invention.
Fig. 3a exemplarily shows a template table (i.e., the above-mentioned extension description table) for storing basic information (corresponding to one-to-one extension) of a template (e.g., basic fields or information including template name template _ base _ name, remark description, etc.).
For example, the extended mode index field is a template _ base _ info _ id field in fig. 3a, and the extended mode name field is a template _ base _ name field in fig. 3 a.
Fig. 3b exemplarily shows a template configuration table (i.e., the above-mentioned extended configuration table) for storing information (e.g., basic information of data format (of the shared metadirectory), source, option, default, etc.) of each item inside the template.
For example, the template _ base _ info _ id field in fig. 3b is the extended mode index field, and the template _ define _ info _ id field is the index field of the extended information field.
Fig. 3c exemplarily shows a basic information table for storing metadata information (i.e., the above-described basic information data), for example, the stored metadata information is data (information) that each kind of template can contain.
For example, column _ base _ info _ id in fig. 3c is the object index field of the basic information table.
Fig. 3d exemplarily shows a metadata extended column data storage table (i.e., the above extended information table) for storing the above extended information data.
For example, column _ base _ info _ id in fig. 3d is an object index field of the basic information table, and template _ define _ info _ id in fig. 3d is an index field of the extended information field.
For example, the row record data stored in the metadata extended column data storage table can be extended to the column field of the same object uniquely identified by column _ base _ info _ id in a database table row-to-column manner.
That is, when the fields of the database are dynamic and can not be determined, an external table is used for data storage, and since a plurality of templates can be set, the fields expanded by each template are different, and the fields of each template need to meet the requirement of later modification, a metadata expansion column data storage table (i.e., the expansion information table) capable of performing the subsequent operation of the data storage is used for data storage. Table 4 shown in fig. 3d is a table extended for data storage, in which only the value entry is a stored value (i.e., the data value of the above-mentioned extension information field).
Fig. 4 exemplarily shows a schematic diagram of an extended configuration GUI that can be used according to the above-described technical solution of the present invention.
As shown in fig. 4, the extended configuration GUI may be used to define or modify (i.e., configure) (e.g., may be stored in a template) an attribute of each basic or extended (information) data item (i.e., the above-mentioned basic information field or the above-mentioned extended information field), or an attribute of a basic or extended (information) data item (e.g., basic information such as a chinese name, an english name, a data format, etc.), and may also store associated information of the basic data item (e.g., the above-mentioned column _ base _ info _ id), so that an extended data item may be implemented.
Optionally, a developer may also define pull-down items of the data items in advance (i.e., a plurality of pull-down options in a pull-down option list corresponding to the data items), and when re-editing the data that has been sorted, a specific pull-down option in the plurality of pull-down options corresponding to a certain data item may be directly selected, so as to implement that the data meets the data requirement defined by the catalog sorting.
According to the above-described aspect of the present invention, extended information data (for example, such as extended field data that can be combined from basic field data by means of direct concatenation or the like) that conforms to different data (for example, directory data) storage and management standards can be extended on the basis of the same basic information data (for example, by the above-described method of defining a template table and a template configuration table). The data storage and management system designed and developed by the above technical solution according to the present invention has a high degree of multiplexing because it is capable of multiplexing basic information data.
According to the technical scheme of the invention, the attributes corresponding to the extended information data (for example, the format of the data or the field, whether the data or the field is open to the society or displayed) can be dynamically configured. For example, the related attributes in the template configuration table may be defined or modified using a template configuration interface (i.e., the extended configuration GUI), and when a user accesses the template configuration table through the user access GUI, data corresponding to a specific data storage and management standard may be generated according to the configured template information (i.e., the information in the template configuration table). Optionally, the custom extension field in each template (i.e., the template configuration table) is stored independently and independently.
According to the above-described aspect of the present invention, a plurality of templates (i.e., a plurality of template configuration tables) may be added, so that different templates corresponding to data storage and management standards of a plurality of regions and/or a plurality of organizations, respectively, are simultaneously configured (i.e., a plurality of templates may coexist simultaneously, and the templates may be switched as needed at any time). Optionally, a specific attribute value may be selected from a plurality of pull-down options in the pull-down list corresponding to the selected attribute in the template, so that during later maintenance, only the attribute values of the relevant attributes in the corresponding template need to be reconfigured in a manner that an ordinary user (for example, a configuration administrator) reselects in the pull-down list, developer intervention is not required, codes do not need to be rewritten, and the later maintenance is simple.
The above-described aspects may be implemented individually or in various combinations, and such variations are within the scope of the present invention.
It will be understood by those of ordinary skill in the art that all or some of the steps of the methods, systems, functional modules/units in the devices disclosed above may be implemented as software, firmware, hardware, and suitable combinations thereof. In a hardware implementation, the division between functional modules/units mentioned in the above description does not necessarily correspond to the division of physical components; for example, one physical component may have multiple functions, or one function or step may be performed by several physical components in cooperation.
