[0022] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0023] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0024] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0025] In the case of using expressions such as "at least one of A, B, and C, etc.", it should generally be interpreted in accordance with the meaning of the expression generally understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.). In the case of using expressions such as "at least one of A, B, or C, etc.", it should generally be interpreted in accordance with the meaning of the expression generally understood by those skilled in the art (for example, "a system having at least one of A, B, or C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0026] A data dictionary is a definition and description of data items, data structures, data flows, data storage, processing logic, etc. Its purpose is to provide a detailed description of each element in the data flow diagram.

[0027] Passive data dictionaries are usually used in related technical systems, such as the FOVA system implemented in the EGL language. When the relevant fields of the data dictionary in the system are modified, the content of the data dictionary must be manually updated. However, during the continuous construction and expansion of the system, the attributes of the relevant fields will continue to increase, and the attributes of some fields will even increase from the initial few to hundreds later, so it is necessary to continuously expand and organize the data dictionary of the relevant fields.

[0028] In the related technology, the data dictionary of related fields is often obtained by manually combing the code and summarizing it. However, the source code of the system is usually very large, involving many statements of field operations. At the same time, the data dictionary of the system is generally updated over time, and there may be data dictionary conversion during the update process. These factors lead to the manual method of generating data dictionaries, which consumes a lot of human resources, has low work efficiency, and is prone to omissions or errors due to the complexity of program logic.

[0029] In view of this, the inventor proposes an automated data dictionary analysis method, which can assist designers in gaining an overall understanding of system functions by automatically collecting and displaying program data dictionaries, effectively saving labor costs and improving the efficiency of analyzing and updating data dictionaries.

[0030] Specifically, the embodiments of the present disclosure provide a data dictionary generation method, a data dictionary generation device, an electronic device, a readable storage medium, and a computer program product.

For the program file 102 received or originally stored in the terminal device 101, the terminal device 101 can use the data dictionary generation method or device provided in the embodiment of the present disclosure to extract the data dictionary 103 of the target field from the program file 102, and display the data dictionary 104 on the display screen of the terminal device 101.

[0037] It should be noted that there may be multiple terminal devices, and different terminal devices may exchange information via wired and / or wireless communication links. The data dictionary generation method provided in the embodiment of the present disclosure may be executed by one of the terminal devices, and the generated data dictionary 103 may be transmitted to another terminal device via a communication link for display.

[0038] The system architecture 100 according to the embodiment of the present disclosure may further include a server 104 .

[0039] The server 104 may be a server or a server group that provides various services. The server 104 and the terminal device 101 may exchange information via wired and / or wireless communication links.

[0041] In addition, the data dictionary generation method provided by the embodiment of the present disclosure can also be executed by other servers or server groups different from the server 104. Accordingly, the data dictionary generation device provided by the embodiment of the present disclosure can also be set in other servers or server groups different from the server 104, which will not be repeated here.

[0042] It should be understood that there may be multiple servers 104 . Figure 1 There is no limit on the number of terminal devices and servers.

[0043] Figure 2 The flowchart of the data dictionary generation method according to the embodiment of the present disclosure is schematically shown.

[0044] like Figure 2 As shown, the method includes operations S210 to S250.

[0045] In operation S210, a target field is acquired.

[0046] In operation S220, the target package is serialized to obtain at least one method object.

[0047] In operation S230, at least one method object is parsed to obtain an assignment statement.

[0048] In operation S240 , a target assignment statement is acquired from the assignment statements based on the target field.

[0049] In operation S250, a data dictionary of the target field is generated according to the target assignment statement.

[0050] According to an embodiment of the present disclosure, the target field may be any one or more variables in a program.

[0051] According to an embodiment of the present disclosure, the target program package may include all program files of the system that require data dictionary generation.

[0052] According to the embodiment of the present disclosure, by serializing the target program package, program objects, method objects, structure objects and database objects can be obtained. Among them, the program object is obtained by serializing the program definition statement, method definition statement and data structure definition statement of each program file in the target program package; the method object is obtained by serializing the method statement of each method in the program file, and each line of method statement is used to implement a grammatical function, wherein the grammatical function includes the assignment grammatical function; the structure object is obtained by serializing the data definition statement of each data structure in the program file; the database object is obtained by serializing the structured query language statement in the program file.

[0053] According to an embodiment of the present disclosure, the target field may appear in statements that implement different grammatical functions. For example, the target field may be used as a variable or an element in an expression in an assignment statement, or as a variable in a conditional statement. In the process of generating a data dictionary for the target field, only the statements in which the target field appears as a variable need to be obtained.

[0054] According to an embodiment of the present disclosure, a serialized object such as a method object may be a data file in the form of binary data. By parsing the method object, the method object may be displayed to facilitate subsequent operations.

[0055] According to an embodiment of the present disclosure, the assignment statement may be a statement with an assignment syntax function identifier. For example, in the EGL language, in the presentation file obtained by parsing the method object, the assignment syntax function identifier may be CodeEvaluation.

[0056] According to an embodiment of the present disclosure, the name of the target field may be used as a keyword to perform keyword search in the acquired assignment statements to obtain a target assignment statement containing the target keyword.

[0057] According to an embodiment of the present disclosure, the attributes of the target field can be obtained according to the target assignment statement, and the data dictionary of the target field can be obtained by summarizing the attributes.

[0058] According to an embodiment of the present disclosure, by obtaining assignment statements in a serialized target program package, and based on the target field to be processed, filtering out target assignment statements from the assignment statements, and then generating a data dictionary for the target field based on the target assignment statements, the problem of omissions or errors that are prone to occur when obtaining the data dictionary for the target field by manually combing through the code is at least partially overcome, thereby effectively reducing the manpower cost required for the generation and maintenance of the data dictionary and effectively improving work efficiency.

[0059] Reference below Figure 3 , combined with specific embodiments Figure 2 The method shown is further explained.

[0060] Figure 3 The following is a schematic diagram schematically showing the workflow of the language parsing system according to an embodiment of the present disclosure.

[0061] like Figure 3 As shown, the system uses a policy chain 320 to identify and parse a target package 310 to generate a syntax tree 330 , and then serializes the syntax tree 330 to obtain a corresponding serialized object 340 .

[0062] According to an embodiment of the present disclosure, the policy chain 320 may include multiple method parsers 321 established for each grammatical function. For example, the policy chain 320 may include method parsers 311 such as Function-define, Evaluation, Expression, Flow-control, Function-call, and Program-call established for method definition statements, assignment statements, expression statements, flow control statements, method call statements, and program call statements in the target package.

[0063] According to an embodiment of the present disclosure, the syntax tree 330 includes a method-type syntax tree 331 generated after parsing each syntax function, for example, a Function syntax tree generated by parsing a method definition statement, an Evaluation syntax tree generated by parsing an assignment statement, and the like.

[0064] According to an embodiment of the present disclosure, the steps of using the policy chain 320 to identify and parse the target package include: using multiple method parsers 321 in sequence to identify each method statement of the target package, and when the identification is successful, using the method parser 321 to parse the method statement, thereby generating a method class syntax tree 331 of the method statement.

[0065] According to an embodiment of the present disclosure, the serialization object 340 may include a method object 341 .

[0066] According to an embodiment of the present disclosure, all method class syntax trees 331 belonging to the same method data block in the target program package are serialized to obtain the method object 341 of the method data block. In some embodiments, a method data block may also be referred to as a function.

[0067] According to the embodiments of the present disclosure, for each method object 341, by parsing the method object 341, a function linked list can be obtained, and the function linked list includes all the information of the method object 341.

[0068] According to an embodiment of the present disclosure, the function linked list may include the name, setting parameters and return value of the corresponding method data block. In some embodiments, the setting parameters and return value of the method data block may be empty, and only the name of the method data block is set. In addition, the function linked list also includes information on all function statements contained in the method data block.

[0069] According to an embodiment of the present disclosure, there are certain differences in the naming of the same grammatical function in the source code and in the function list. For example, for the assignment grammatical function, its name in the source code is Evaluation, and its name in the function list is CodeEvaluation.

[0070] According to an embodiment of the present disclosure, based on the name of the assignment syntax function in the function chain list, the statement containing the name can be extracted from the function chain list to obtain the assignment statement.

[0071] According to an embodiment of the present disclosure, each assignment statement contains a variable name value, an assignment element alAssignment, and an operator alOperator. By matching the name of the target field with the variable name in all assignment statements, statements with the same variable name and target field name are extracted from the assignment statements, thereby obtaining the target assignment statement. For example, the target field "A" exists in the value column of one of the assignment statements, and in the alAssignment column of other assignment statements. The target assignment statement for the target field "A" obtained by matching is only the assignment statement where "A" exists in the value column.

[0072] According to an embodiment of the present disclosure, the assignment elements and operators can be combined according to preset rules to restore them to expressions. For example, the assignment elements and the elements in the operator can be interlaced and spliced ​​with "," as a separator to restore them to expressions. For example, if the assignment elements are "1" and "A" respectively, and the operator is "+", the restored expression is 1+A; further, the line of statements can also be restored to the assignment statement in the source code: D=1+A.

[0073] According to the embodiments of the present disclosure, each restored expression can be used as an assignment attribute of the target field, and all the assignment attributes are integrated to obtain the data dictionary of the target field.

[0074] In some embodiments, the assignment statement may also include relevant comment information. When generating a data dictionary, for example, a comment symbol such as “ / / ” may be added to the comment information and added to the relevant assignment attributes.

[0081] The generating module 450 is used to generate a data dictionary of the target field according to the target assignment statement.

[0082] According to an embodiment of the present disclosure, by obtaining assignment statements in a serialized target program package, and based on the target field to be processed, filtering out target assignment statements from the assignment statements, and then generating a data dictionary for the target field based on the target assignment statements, the problem of omissions or errors that are prone to occur when obtaining the data dictionary for the target field by manually combing through the code is at least partially overcome, thereby effectively reducing the manpower cost required for the generation and maintenance of the data dictionary and effectively improving work efficiency.

[0083] According to an embodiment of the present disclosure, at least one line of method statements constitutes at least one method data block. The processing module 420 includes a first processing unit and a second processing unit.

[0084] The first processing unit is used to parse the method statement corresponding to each method data block of the target program package using the policy chain to obtain a method class syntax tree.

[0086] According to an embodiment of the present disclosure, the policy chain includes a plurality of method parsers established for each grammatical function. The first processing unit includes a first processing sub-unit and a second processing sub-unit.

[0087] The first processing subunit is used to use multiple method parsers in sequence to identify method statements.

[0088] The second processing subunit is used to parse the method statement using the method parser that successfully identifies the method statement to generate a method class syntax tree.

[0089] According to an embodiment of the present disclosure, the parsing module 430 includes a first parsing unit, a second parsing unit, and a third parsing unit.

[0090] The first parsing unit is used to parse at least one method object to obtain at least one function linked list.

[0092] The third parsing unit is used to extract a statement containing a function name from at least one function linked list to obtain an assignment statement.

[0093] According to an embodiment of the present disclosure, the assignment statement includes a variable name. The selection module 440 includes a first selection unit and a second selection unit.

[0094] The first selection unit is used to match the target field with the variable name of each line of assignment statement to obtain a matching result.

[0095] The second selection unit is used to determine that the assignment statement is a target assignment statement when the matching result is a successful match.

[0096] According to an embodiment of the present disclosure, the target assignment statement includes an assignment element and an operator. The generation module 450 includes a first generation unit and a second generation unit.

[0097] The first generating unit is used to combine the assignment elements and operators according to preset rules for each line of target assignment statement to generate assignment attributes.

[0098] The second generation unit is used to record all the assigned attributes to generate a data dictionary of the target field.

[0099] According to the embodiments of the present invention, any one or more of the modules, submodules, units, and subunits, or at least part of the functions of any one of them can be implemented in one module.
