Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The directory operation method provided by the present invention may be applied to an application scenario shown in fig. 1, where fig. 1 is an application scenario diagram of the directory operation method in an embodiment, and the application scenario may include a terminal 100 and a server 200, and the terminal 100 may communicate with the server 200 through a network. The server 200 is used for managing a directory of a database, and the terminal 100 may operate the directory through the server 200. Specifically, the terminal 100 may generate a directory operation request carrying a directory operation instruction and a current operation serial number, and then send the request to the server 200, the server 200 may extract the current operation serial number carried by the directory operation request after receiving the directory operation request, then the server 200 obtains a locally stored historical operation serial number, performs difference processing on the current operation serial number and the historical operation serial number, obtains a difference value between the current operation serial number and the historical operation serial number, and then the server 200 may compare the difference value with a preset serial number increment, and if the difference value is greater than the serial number increment, the server 200 performs a corresponding operation on the directory according to the directory operation instruction.
The terminal 100 may be, but is not limited to, various personal computers, notebook computers, smart phones, and tablet computers, and the server 200 may be implemented by an independent server or a server cluster formed by a plurality of servers.
in an embodiment, a directory operation method is provided, referring to fig. 2, fig. 2 is a schematic flowchart of a directory operation method in an embodiment, which is described by taking the method as an example applied to the server 200 in fig. 1, and the directory operation method may include the following steps:
Step S101, obtaining a directory operation request of the terminal.
in this step, the server 200 may obtain a directory operation request of the terminal 100, where the directory operation request may be initiated by the terminal 100, and the terminal 100 may generate a directory operation instruction according to an actual operation requirement, where the instruction is mainly used to refer to the server 200 performing a corresponding operation on a directory, and the operation on the directory may be to add data in the directory, modify data in the directory, query data of the directory, delete data of the directory, and the like, and a specific operation may be set by a user, for example, if the user needs to add some data in the directory, the content that needs to be added may be input to the terminal 100, and then the terminal 100 generates a directory operation instruction according to the content that needs to be added. Next, the terminal 100 further needs to obtain a current operation serial number, where the current operation serial number is mainly used for identifying an operation serial number that needs to be currently operated on the directory. In practical applications, a string of numbers such as 102 may be used as the current operation serial number, or a combination of a primary and a secondary numbers such as a102 may be used as the current operation serial number. Each time the terminal 100 needs to operate the directory, a directory operation instruction may be generated and a current operation serial number may be obtained, then the directory operation instruction and the current operation serial number may be converted into a directory operation request according to a specific communication protocol, the directory operation request may be sent to the server 200, and after the server 200 obtains the directory operation request, the directory operation instruction and the current operation serial number may be extracted from the request.
and step S102, acquiring a history operation serial number prestored locally.
The step is mainly that the server 200 obtains a historical operation serial number pre-stored locally, where the historical operation serial number is generated when the server 200 operates the directory last time. The server 200 may perform operations on the directory, such as deleting data of the directory, modifying data of the directory, and the like, and each time the server 200 performs a corresponding operation on the directory, an operation serial number may be generated, and before a next directory operation instruction comes, the operation serial number may be stored locally in the server 200 as a historical operation serial number. When the next directory operation instruction comes, that is, after step S101, the server 200 may obtain the historical operation serial number, where the historical operation serial number is used to identify the operation serial number of the server 200 that has last operated on the target, and the server 200 needs to obtain the historical operation serial number first before operating on the directory each time, as a reference for comparing with the current operation serial number of the terminal 100, so as to determine whether to operate on the directory.
step S103, the current operation serial number and the historical operation serial number are subjected to difference processing, and the difference value between the current operation serial number and the historical operation serial number is obtained.
in this step, after obtaining the current operation serial number and the historical operation serial number, the server 200 may perform a numerical difference between the current operation serial number and the historical operation serial number to obtain a difference between the current operation serial number and the historical operation serial number. Specifically, if the current operation serial number is 103 and the historical operation serial number is 102, the difference between the current operation serial number and the historical operation serial number is 1; if the current sequence number is a103 and the historical operation sequence number is a102, only the numerical value parts of the sequence numbers, namely 103 and 102, can be subtracted to obtain a difference value of 1.
And step S104, if the difference value is the same as the set serial number increment, executing corresponding operation on the directory according to the directory operation instruction.
the sequence number increment may be preset in the server 200, and is mainly used for updating the historical operation sequence number each time the server 200 successfully operates the directory, and the sequence number updating operation is incremental, that is, the sequence number increment is added to the original historical operation sequence number to form a new historical operation sequence number. For example, the original historical operation serial number is 101, and the serial number increment is 1, then after the server 200 successfully operates the directory, if the data deletion succeeds, 1 is added on the basis of 101, so as to obtain a new historical serial number 102 to replace the original historical operation serial number. Before the server 200 operates the directory, it needs to first determine whether the directory operation instruction carried in the directory operation request is an effective operation instruction, and for an ineffective operation instruction, the server 200 does not execute a corresponding operation on the directory, that is, the server 200 only executes an operation instruction meeting a certain requirement. Specifically, the server 200 compares the difference between the current operation serial number and the historical operation serial number with a preset serial number increment, and if the difference is the same as the serial number increment (if the difference is 1, the serial number increment is also 1), it may be determined that the directory operation instruction conforms to the operation order of the directory, that is, it may be determined that the directory operation instruction is an effective operation instruction, so that the server 200 may perform a corresponding operation on the directory according to the directory operation instruction; however, if the difference is different from the sequence number increment (for example, the difference is 2, and the sequence number increment is 1), it indicates that the directory operation instruction may have a problem of cross-order operation, if such an operation instruction is executed, data of the directory may be misoperated, there is a risk that the data being modified is modified into other data, and the like, so that an invalid operation instruction is determined when the directory operation instruction is executed, the server 200 may not execute corresponding operation on the directory, thereby ensuring that the operation executed on the directory can be executed according to a certain order, avoiding the problem that the directory operation order is disordered to generate the misoperation, and the directory needs to be repeatedly operated for many times, and improving the efficiency of operating the directory.
In one embodiment, if the difference between the current operation serial number and the historical operation serial number is not the same as the set serial number increment, the server 200 may also transmit its stored historical operation serial number to the terminal 100. If the difference is different from the serial number increment, it indicates that the directory operation instruction sent by the terminal 100 cannot be executed by the server 200, and therefore the directory operation instruction is an invalid instruction for the terminal 100, and the terminal 100 needs to generate a directory operation request again to allow the server 200 to execute the directory operation request to meet the operation requirement of the terminal on the directory. The invalid operation instruction is caused by an error of the current operation serial number when the operation instruction is invalid, that is, the terminal 100 generates an operation serial number which does not meet the requirement, so that the server 200 may transmit the stored historical operation serial number to the terminal 100 when the instruction is invalid, so that the terminal 100 may regenerate the current operation serial number based on the historical operation serial number. Specifically, if the current operation serial number generated by the terminal 100 for the first time is 102, and the historical operation serial number stored by the server 200 is 103 and the serial number increment is 1, a difference value-1 different from the serial number increment 1 is obtained, and at this time, the server 200 may feed back the historical operation serial number 103 to the terminal 100, so that the terminal 100 regenerates the operation serial number 104 according to the historical operation serial number 103, and the requirement of the terminal 100 for operating the directory is met.
when the server 200 operates on the directory, two directory operation results may be obtained, one is successful operation, and the other is failed operation. The two operation results are described by taking the directory modification as an example, when the server 200 modifies the directory, two results of successful modification and failed modification may be obtained, if the server 200 modifies the data a in the directory, the server 200 may first query whether the data a exists in the directory, and in the case that the data a exists, the server 200 can modify the data a, which indicates that the modification is successful; if the directory does not contain the data a, the server 200 cannot modify the data a, and the server 200 obtains a directory operation result of which the modification fails.
Based on this, in some embodiments, the server 200 may obtain a directory operation result of operating the directory after performing a corresponding operation on the directory according to the directory operation instruction, and perform subsequent processing based on the directory operation result.
If the directory operation result is successful, the server 200 needs to update the historical operation serial number by using a serial number increment, for example, before the operation is successful, the historical operation serial number is 102, and the serial number increment is preset to 1, after the operation is successful, the historical operation serial number is updated from 102 to 103, and the updated historical operation serial number is sent to the terminal 100, so that the terminal 100 can regenerate the current operation serial number when the directory is operated next time based on the updated historical operation serial number.
If the directory operation result is an operation failure, the server 200 needs to obtain a prompt message of the reason of the operation failure. The reason prompt information is mainly used for prompting the reason causing the operation failure, for example, when the data a of the directory is modified, if the data a does not exist in the directory, the reason prompt information of the operation failure may be "data a does not exist in the directory". Then, the server 200 may feed back the prompt information of the reason of the operation failure to the terminal 100, and at the same time, the server 200 may also send the stored historical operation serial number and the prompt information of the reason of the operation failure to the terminal 100, so as to facilitate the user to check and correct the error, and facilitate the terminal 100 to resend the directory operation request to the server 200.
the directory operation method comprises the steps of obtaining a directory operation request of a terminal, wherein the directory operation request carries a directory operation instruction and a current operation serial number, then obtaining a locally pre-stored historical operation serial number, subtracting the current operation serial number from the historical operation serial number to obtain a difference value, then comparing the difference value with a set serial number increment, and if the difference value is the same as the serial number increment, executing corresponding operation on a directory according to the directory operation instruction carried by the directory operation request. According to the scheme, when a directory operation request is received, the current operation serial number carried by the directory operation request is firstly differed with the historical operation serial number, so that the difference value of the directory operation request is obtained, if the difference value is the same as the set serial number increment, the directory operation instruction can be judged to be an effective operation instruction, then corresponding operation can be executed on the directory according to the directory operation instruction, the operation sequence of the directory can be consistent with the management sequence of the request, the problem that the directory operation sequence is disordered to generate misoperation, the directory needs to be repeatedly operated for many times is avoided, and the efficiency of operating the directory is improved.
It is understood that what operations the server 200 performs on the directory mainly depends on the directory operation instructions, and the specific form of the directory operation instructions may be various. In one embodiment, the directory operation instructions may include directory lookup instructions, directory modification instructions, directory add instructions, and/or directory delete instructions. The directory query instruction can be used for querying the nodes of the directory, the directory modification instruction can be used for modifying the nodes of the directory, the directory addition instruction can be used for adding the nodes of the directory, and the directory deletion instruction is used for deleting the nodes of the directory.
In one embodiment, the directory in which the server 200 needs to operate may be a tree directory, which is a type of directory that enables efficient organization and management of data. In this embodiment, the directory that the server 200 needs to operate may include a plurality of data nodes and a plurality of relationship nodes, where the plurality of data nodes are configured in the directory according to a set hierarchical relationship, and the relationship nodes are generally used for recording an association relationship between the plurality of data nodes. The server 200 may operate on the data nodes and the relationship nodes in the directory based on the directory operation instruction, and the server 200 may perform different operations according to the directory operation instruction and the nodes of the directory that need to be operated.
Specifically, when the directory operation instruction is a directory query instruction, the step of the server 200 performing corresponding operation on the directory according to the directory operation instruction may include: and acquiring node information of the node, and sending the node information to the terminal. The node may be a data node or a relationship node, and a data leaf node may also be provided below the data node, and the data leaf node may be used to link and describe a specific data resource, and in the case of having a data leaf node, the relationship node may also record an association relationship between each data leaf node. When the server 200 needs to perform the query operation, since the node does not need to be changed and is information of the query node, the server 200 may determine which node the terminal 100 needs to query according to the directory query instruction, extract attribute information (creator, modification time, and the like, which may be customized by a user) from the node, and after obtaining the node information of the node, send the node information to the terminal 100 to complete the query processing.
when the directory operation instruction is a directory modification instruction, the step of the server 200 performing corresponding operation on the directory according to the directory operation instruction may include: if the node is a data node, updating node information of the data node according to the modification content carried by the directory modification instruction; and if the node is the relational node, determining the associated node according to the modification content carried by the directory modification instruction, judging whether the associated node exists, and if so, updating the node information of the relational node according to the node information of the associated node. Specifically, when the server 200 needs to modify a node of the directory, the corresponding modification operation needs to be performed in conjunction with the specific type of the node. If the node that the server 200 needs to modify is a data node, the server 200 may obtain the modification content carried by the directory modification instruction sent by the terminal 100, and update the node information of the data node according to the modification content, where the modification content may also be a content that updates the node information of a data leaf node under the data node, and in this case, the server 200 may update the node information of the corresponding data leaf node. If the server 200 needs to modify the relationship node, since the relationship node records the association relationship between two nodes, and modifying the relationship node can be regarded as modifying the association relationship between some two nodes recorded by the relationship node, when modifying the relationship node, the server 200 can extract specific modification content from the directory modification instruction, where the modification content may be associating the data node X with the data node Y in the relationship node, and associating the data node X with the data node Z, so that after obtaining the modification content, the server 200 can determine whether the association node needing to be modified exists in the directory, for example, modifying the data node X with the data node Y to associate the data node X with the data node Z, and then it needs to determine whether the data node X and the data node Z exist in the directory, if so, updating the node information of the relation node, namely updating the original node information 'association between the data node X and the data node Z' into 'association between the data node X and the data node Z', and finishing the modification operation of the relation node; if data node X or data node Z does not exist in the directory, information of operation failure may be fed back.
When the directory operation instruction is a directory add instruction, the step of the server 200 performing corresponding operation on the directory according to the directory operation instruction may include: if the node is a data node, newly adding the data node in the directory by using newly added data node information carried by the directory adding instruction; if the node is a relationship node, judging whether the corresponding associated node exists in the directory according to the information of the newly added relationship node carried by the directory adding instruction, and if so, newly adding the relationship node in the directory. Specifically, when the server 200 receives a directory addition instruction, a corresponding node may be newly added in the directory according to the instruction. If the node to be newly added is a data node, the server 200 may determine the position of the data node to be newly added in the directory according to the information of the newly added data node (such as information of a position of the newly added node, a creator of the newly added node, a node creation time, and the like) carried in the directory operation instruction, then newly add the data node at the corresponding position in the directory and give the data node related node information; if the node needing to be added is the relationship node, the information of the added relationship node carried by the node needing to be added is extracted from the directory adding instruction, for example, the added relationship node is used for describing the association relationship of the nodes, and the like, and then whether the corresponding association node exists in the directory is further judged, if so, the relationship node is added in the directory, and if not, the information of operation failure can be fed back.
When the directory operation instruction is a directory deletion instruction, the step of the server 200 performing corresponding operation on the directory according to the directory operation instruction may include: if the node is a data node, judging whether a related node associated with the data node exists in the directory by using the relational node, and if not, deleting the data node; and if the node is the relation node, deleting the relation node. Specifically, if the directory operation instruction received by the server 200 is a directory deletion instruction, the server 200 may perform deletion processing on nodes in the directory according to the instruction. If the node to be deleted is a data node, the server 200 needs to determine whether an associated node associated with the data node to be deleted exists in the directory by querying a corresponding relationship node, and if so, the server 200 cannot execute the deletion instruction; if there is no associated node, the data node can be correctly deleted by the server 200. For the relationship node, after the server 200 receives the directory deletion instruction, the position of the relationship node to be deleted may be determined, and then the relationship node may be deleted from the directory without checking.
in an embodiment, when the directory operation instruction is a directory modification instruction, a directory addition instruction, or a directory deletion instruction, the server 200 may obtain and store corresponding operation information (e.g., information about what a specific operation instruction is, what a specific operation object is, etc.). The server 200 may also store the directory information of the directory at certain operation intervals (e.g., every two operation intervals), and store the number of times the directory has been changed, which may be compared with the number of recording operations in the memory directory to ensure consistency of storage. The whole data catalog is existed in the memory and the disk storage at the same time, and only the operation of changing the catalog is sent to the disk storage.
In one embodiment, the directory in which the server 200 needs to operate may be a tree directory for managing government affairs data.
when government affair data is managed, a database is mainly used for managing the government affair data in the traditional technology, and when the government affair data is managed in the database mode, only special fields can be set to mark the owner of each entry, or the data is divided into a plurality of tables according to the organization level for storage and management. When the government affair data is more, the added fields occupy extra storage space, the performance of multi-table query is greatly influenced by massive data tables, and the database scheme is a flat method, has fewer layers, is difficult to manage the access authority of the government affair data resources and is not beneficial to maintaining the government affair data resources.
The embodiment manages government affairs data by adopting a tree directory, and the tree directory can comprise a plurality of data nodes and relationship nodes. The data nodes are configured in a tree-shaped directory according to the hierarchical relationship of the organization, and can also be provided with data leaf nodes which are mainly used for linking and describing government affair data; and the relationship node is used for storing the constraint relationship of any two data leaf nodes. The scheme of the embodiment can use the tree structure to organize the government affair data resources according to the logic of the government affair organization, has clear hierarchy, is convenient for business processing, and is convenient for the work of data management and development based on the business in the future.
In an example application, there is provided a catalog management system, which can be used for managing government affairs data, and referring to fig. 3, fig. 3 is a block diagram of a structure of the catalog management system in an embodiment, which can include: the device comprises an operation distribution module, a directory operation module, a storage module, a log module and an exception handling module; the directory operation module can comprise a relation node operation module and a data node operation module; the storage module may be used for operation storage and directory storage. The application example can manage the government affair data resources by using a tree-shaped directory, data nodes in the tree-shaped directory represent the levels of organizations on the actual business or the levels of affairs, data leaf nodes under the data nodes link and describe the government affair data resources, the directory further comprises a class of nodes as relationship nodes, and the relationship nodes can store the constraint relationship of some two data leaf nodes, for example, when a certain data leaf node or a parent node thereof is deleted, whether the data leaf node has the constraint relationship with other data nodes or not is checked in the relationship nodes.
Referring to fig. 4, fig. 4 is a flowchart illustrating a process of the directory management system in an embodiment, where the specific data process flow is as follows:
In step S201, for a directory management request (for adding, deleting, modifying or querying a data node, a data leaf node or a relationship node), the operation allocation module allocates the requests to the corresponding directory operation modules for processing, and the allocated directory operation modules are recorded by the log module. For the directory management request which can not be processed by finding the corresponding method, an operation exception will be generated, and the exception information will be recorded by the log module.
In step S202, the directory operation module performs corresponding operations on the directory according to the operation instruction carried in the previous directory management request, where the directory operation module is divided into a data node operation module and a relationship node operation module, which include sub operation modules for respective types of nodes.
Specifically, when querying the relationship node and querying the data node, the attribute information in the corresponding node is extracted. When the data nodes are added, the positions, names and other specific attributes of the nodes are set according to the operation instructions carried in the request; when the relationship node is added, the node with the constraint relationship is checked to check whether the node with the constraint relationship exists in the directory, if so, the relationship node is added, otherwise, the operation abnormity can be generated. When the data node is modified, the position of the data node to be modified is determined according to the instruction carried by the request, and the information of the data node is updated; when the relationship node is modified, the position of the relationship node to be modified is determined according to the instruction carried by the request, the information of the node is updated, before the update, whether the associated node exists needs to be checked, and if the associated node exists, the information of the node is updated. When deleting a data node, firstly checking whether the node and child nodes thereof exist and whether constraints exist, and only the nodes which do exist and have no relation node constraints can be correctly deleted; when the relation node is deleted, the relation node is directly removed from the directory without checking.
The above directory operations such as addition, deletion and modification involve the change of the directory, and in order to ensure that the directory operation sequence is consistent with the sequence of the management requests, an operation power of the directory (i.e. the directory operation sequence number) is set, and is increased by 1 every time the directory is successfully modified, and each directory management request involved in the directory modification must have an operation power, and the directory operation module only operates the management requests with more than one operation power than the current operation power.
