Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a flow chart of a method for establishing a railway land management department model in an embodiment of the present invention, and as shown in fig. 1, the method for establishing a railway land management department model provided in the embodiment of the present invention includes:
and 110, building a multi-node tree model of the railway land management department according to the membership of the railway land management department.
Specifically, the railway land management is an important link of railway transportation work, and needs the cooperation of each management department of the railway to manage, and according to the membership of each management department, a multi-node tree model of the management department of the railway land can be built.
Fig. 2 is a structural model of a multi-node tree of a railway land management department in the embodiment of the present invention, as shown in fig. 2, node #001, node #011, node #012, node #013, node #021 and the like represent a railway management department mechanism, and as known from a tree structure model in the figure, node #011 is subordinate to node #001, so that node #011 is presented as a branch of node #001, and node #021 is subordinate to node #011, so that node #021 is presented as a branch of node # 011. And so on, according to the membership of each management department of the railway, a model of a multi-node tree of the land management departments of the railway is established as shown in fig. 2.
And 120, if at least two first child nodes of different parent nodes exist in the multi-node tree model, reserving the first child node corresponding to any parent node and all descendant nodes of the first child node, and deleting the rest of the first child nodes corresponding to the parent nodes and all descendant nodes of the first child node to obtain the multi-node tree trunk model.
Specifically, as shown in fig. 2, an upper node of each node in the multi-node tree model is used as a parent node of the node, for example, an upper node of a node #011 is a node #001, then the node #001 is the parent node of the node #011, and the node #011 is a child node of the node # 001; meanwhile, the node #011 is also an upper node of the node #021, so that the node #011 is also a parent node of the node #021, and the node #021 is a child node of the node # 011. In fig. 2, except for the node #001, the rest nodes are all nodes in the subtree rooted at the node #001, and then except for the node #001, the rest nodes are all descendant nodes of the node # 001. From this, it is clear that the parent nodes of the node #012 are two, i.e., the node #001 and the node #013, and the offspring nodes corresponding to the node #012 are the node #022, the node #023, the node #033, the node #034, the node #035, and the node #036.
The table 1 is a conventional data structure storage table, as shown in the table 1, the data corresponding to the rows with serial numbers of 6-12 and 14-20 in the table are identical, that is, because the node #012 has two different parent nodes, namely the node #001 and the node #013, the node #012 and all corresponding offspring nodes are stored twice to correctly establish the parent-child relationship, the conventional multi-node tree model is established by adopting the method, the same department node is stored for multiple times, the storage space is occupied, the method can cause a plurality of node IDs, the data is disordered, and great difficulty is brought to the subsequent data merging, classifying and the like.

In the embodiment of the invention, if at least two first child nodes of different parent nodes exist in the multi-node tree model, the first child node corresponding to any parent node and all descendant nodes of the first child node are reserved, and the other first child nodes corresponding to the parent nodes and all descendant nodes of the first child nodes are deleted, so that the multi-node tree trunk model is obtained. As shown in fig. 2, the node #012 has two different parent nodes, namely a node #001 and a node #013, so that the node #001 or a child node #012 corresponding to the node #013 is reserved, for example, the child node #012 corresponding to the node #001 is reserved, and all the child nodes corresponding to the child node #012 are reserved, namely, the data with serial numbers of 6-12 rows in the table 1 is reserved; and deleting the child node #012 corresponding to the node #013 and deleting all descendant nodes corresponding to the child node #012, namely deleting the data with the sequence numbers of 14-20 rows in the table 1. As shown in table 2, the data model object table in table 1 passes through the child node #012 corresponding to the reserved node #001 and all the offspring nodes corresponding to the reserved child node #012, and simultaneously deletes the child node #012 corresponding to the node #013 and deletes all the offspring nodes corresponding to the child node #012, so as to obtain the data model object table in table 2, and the data model object table is used for storing basic data. Therefore, in table 2, child node #012 and all corresponding child node data are saved only once, so that the storage space is saved.
It can be understood that the child node #012 corresponding to the node #001 and all the descendant nodes corresponding to the child node #012 may be deleted, and meanwhile, the child node #012 corresponding to the node #013 and all the descendant nodes corresponding to the child node #012 are reserved, so that the structural relationship of each node, that is, the railway management department, can be flexibly changed and configured.

As shown in table 3, in step 120, since the child node #012 corresponding to the node #013 and all descendant nodes corresponding to the child node #012 are deleted, in order to correctly establish the parent-child relationship of the tree structure, the table 3 is used for recording the mounting relationship between the child node #012 and the node #013, where the mounting object is the node #013 and the mounted object is the child node #012.
It can be understood that if the child node #012 corresponding to the node #001 and all the descendant nodes corresponding to the child node #012 are deleted in step 120, and the child node #012 corresponding to the node #013 and all the descendant nodes corresponding to the child node #012 are reserved, the mounting relationship between the node #001 and the child node #012 can be recorded in table 3, and the method provided by the embodiment of the present invention not only can save storage space, but also can flexibly change the structural relationship of the railway management department. For example, if the post maintenance is required, a child node #012 needs to be added under the node #011, then only the mounting relationship between the child node #012 and the node #011 needs to be added in the table 3 mounting record table, and this way is simpler and more flexible, so that the railway land is in accordance with the under-line management mode, and the post data maintenance is easy.
